Explanation:
The end result is glucose, with oxygen being the waste product. The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart.
The Lannister’s family went to bed one frigid winter night and were found deceased the next day. A squirrel’s nest was found in their chimney. What happened to the Lannisters?
Answer:
They died due to suffocation.
Explanation:
The whole Lannister’s family died due to the shortage of oxygen in the room because of squirrel’s nest in the chimney. Chimney is the only way for the removal of toxic gases and smoke produced from the burning of wood. The squirrel’s nest block the passage and the smoke and toxic gases stay in the house which causes suffocation and the whole Lannister’s family died.
How osmosis works in the three fluid compartments of the body
Answer:
Explanation:
In the body, water moves through semi-permeable membranes of cells and from one compartment of the body to another by a process called osmosis. Osmosis is basically the diffusion of water from regions of higher concentration to regions of lower concentration, along an osmotic gradient across a semi-permeable membrane.
help asap giving branlist plsss helppp
Answer:
except option 2 all of them are applied
Explanation:
If each NADH generates "3 ATP" molecules and each FADH2 generates 2 ATP molecules, calculate the number of ATP molecules generated from one saturated 18 ‑carbon fatty acid.
Answer:
90 ATP
Explanation:
Every acetyl-CoA yields 3 NADH and 1 FADH2
18 carbon fatty acid is known to have 9 Acetyl CoA.
1 acetyl CoA produces a total of 10ATP.
Since the 18 carbon fatty acid has a total of 9 Acetyl CoA then the total number of ATP produced is 9* 10 which results in 90 ATP being formed when it passes through the various reaction mechanisms.

What are the five senses? Type your brainstorm
Answer:
Sense: Smell, Taste, Touch, Sight, Hearing
Explanation:
Answer:
touch, sight, hearing, smell, taste
Explanation:
Touch is thought to be the first sense that humans develop, according to the Stanford Encyclopedia of Philosophy. Touch consists of several distinct sensations communicated to the brain through specialized neurons in the skin. Pressure, temperature, light touch, vibration, pain and other sensations are all part of the touch sense and are all attributed to different receptors in the skin.
Sight, or perceiving things through the eyes, is a complex process. First, light reflects off an object to the eye. The transparent outer layer of the eye called the cornea bends the light that passes through the hole of the pupil. The iris (which is the colored part of the eye) works like the shutter of a camera, retracting to shut out light or opening wider to let in more light.
hearing sense works via the complex labyrinth that is the human ear. Sound is funneled through the external ear and piped into the external auditory canal. Then, sound waves reach the tympanic membrane, or eardrum. This is a thin sheet of connective tissue that vibrates when sound waves strike it.
Humans may be able to smell over 1 trillion scents, according to researchers. They do this with the olfactory cleft, which is found on the roof of the nasal cavity, next to the "smelling" part of the brain, the olfactory bulb and fossa.
The gustatory sense is usually broken down into the perception of four different tastes: salty, sweet, sour and bitter. There is also a fifth taste, defined as umami or savory. There may be many other flavors that have not yet been discovered. Also, spicy is not a taste.

Explanation:
Describe the biosynthetic pathway that produces catecholamines such as norepinephrine and epinephrine from amino acid precursors and explain how the lack of available amino acids precursors would impact homeostasis regulated by catecholamines.
Answer:
Tyrosine and phenylalanine are amino acids required for the synthesis of catecholamines
Explanation:
The catecholamines are hormones composed of a catechol ring group (benzene) and an amine lateral chain. One of the most common catecholamines is the neurotransmitter norepinephrine (noradrenaline). The biosynthesis pathway of the norepinephrine hormone includes the following steps: 1-tyrosine hydroxylase produces L-DOPA from tyrosine, 2-L-DOPA is subsequently tranformed into dopamine by the L-amino acid decarboxylase, and finally, 3-this chemical precursor is converted into norepinephrine by the action of the dopamine β-hydroxylase.
Phenylketonuria is a congenital metabolic disease associated with a decrease in the metabolism of phenylalanine (Phe), which is an amino acid residue that acts as a precursor of different catecholamines including dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline). Dietary restriction of tyrosine and phenylalanine is the most common treatment against phenylketonuria.

Some organisms are made of single cells and live in the hot acidic environment of deep ocean vents.
Some organisms are single cells and live one the surface of your skin.
And there are small multicellular organisms that make fuzzy circular growth on old bread.
And of course, roses with pretty flowers are organisms.
And whales.
That’s a lot of diversity. So let’s say I think those creatures are just so different that they just couldn’t ALL be related to each other. Using specific traits, convince me that all of these organisms can be traced back to a common ancestor. (At least 6 well-chosen traits required for full credit.)
Write your answer in the essay space.
Answer:
All organisms are composed of cells that share a structural organization and play roles in similar biological processes.
Explanation:
All living organisms can be grouped in terms of cellular organization, functioning, and structure. These features enable us to define them as “subjects” of life. Organisms share basic biological mechanisms such as, among others, growth, homeostasis, development, energy processing, reproduction, etc. Moreover, life is also defined by the presence of essential biomolecules such as DNA, RNA, proteins and lipids. Finally, the cell is considered to be the basic unit of every life form, and organisms may be formed by one (unicellular) or more cells (multicellular). The fundamental feature of the cell is the presence of a membrane that separates it from the external environment, thereby defining its internal environment.
You are a graduate student in the lab of a famous fly geneticist. You need to analyze a batch of mutant flies that were recently created in her laboratory to identify the single gene that is most likely mutated in each of the flies. Drag the mutations on the left to the appropriate blanks on the right to complete the sentences.
a. knirps (a gap gene)
b. hunchback (a gap gene)
c. hedgehog (a segment-polarity gene)
d. wingless (a segment-polarity gene)
e. kruppel (a gap gene)
f. even-skipped (a pair-rule gene)
1. Mutant fly F has predominantly lost abdominal structures, which is likely the result of a mutation in_____.
2. The wings are missing in mutant fly L, which is likely the result of a mutation in______.
3. Thoracic and abdominal structures are missing in mutant fly Q. The gene most likely responsible for this mutation is______.
4. Segment-sized sections of every other segment are missing in mutant fly Z. One likely candidate gene is_______.
5. Mutant fly X has lost the head and thorax. The gene most likely responsible for this mutation is_______.
6. The mutation observed in mutant fly O resulted in defects within the anterior or posterior regions of each segment. The gene that most likely caused this mutation is_______.
Answer:
knirps (a gap gene)
wingless (a segment-polarity gene)
kruppel (a gap gene)
even-skipped ( a pair-rule gene)
hunchback (a gap gene)
hedgehog (a segment-polarity gene)
Explanation:
The gap, segment-polarity and pair-rule genes play central roles in controlling embryonic development of arthropods. In the first place, the gap genes are associated with the formation of contiguous body segments, thereby mutations in these genes result in gaps in the normal body plan of the embryo. For example, in Drosophila melanogaster, mutations in the knirps, Krüppel and hunchback genes result in deletion of body segments. These genes are also known to regulate segment polarity genes, which determine the polarity of the embryonic parasegments by modulating Wnt and Hedgehog signaling pathways. Finally, the pair-rule genes work together with gap genes to control embryonic development of alternating body segments.
What would cause antibodies to attack the cells of the body?
Answer:
In autoimmune diseases, such as lupus, multiple sclerosis and rheumatoid arthritis, people produce antibodies that stick to their body's own proteins and attack healthy cells.
Explanation:
Which reason best explains why bacteria are good at causing infections in other organisms? It would not be able to divide. Bacteria are transmitted easily and reproduce quickly. Bacteria evolve slowly as they pass on genetic information. Bacteria are easily killed by a host’s immune system or antibiotics.
Answer:
Bacteria are transmitted easily and reproduce quickly
Explanation:
Bacteria are organisms that have a single cell. The process of reproduction of the bacteria is binary fission. The parent cell divides into the daughter cell. The DNA of the parent cell gets copied and gets divided by forming the identical daughter cells. Some bacteria have nutritional values in them while the others are infectious. They can divide at an alarming rate if they receive favorable conditions. Also, they are easily communicable and transmittable. It is because of this reason that the bacteria are good at causing infections in other organisms.
What is the allele frequency?
Answer:
Explanation:
Allele frequency is the how often or what's the percentage of a particular allele in a population. Allele is referred to as version of a gene that is located on the chromosome.
For example, a gene causing death in rats might have alleles, W and w. Each would be a separate allele and the frequency would be how often or what's the percentage of W or w that is present in the population.
Suppose we are trying to find frequency of W or w allele in a population then the formula is
Allele Frequency = [# of copies of certain allele (either W or w)] / [Total number of W and w alleles]
Now suppose we have 4 WW and 2 ww in a population.
First we count up W allele then we have (4 * 2)= 8 W (we multiplied by 2 because each organism has WW, 4 WW is short of of writing WW , WW, WW, WW)Same concept for 2ww, we have total w = 2 * 2 = 4wTotal alleles = W + w = 8 +4 =12
Allele Frequency for W = 8 / 12 = 66.67%
Allle Frequency for w = 4 / 12 = 33.33%

what is a type of emigration where offspring move
away from their parents.
Answer:Dispersal
Explanation: This refers to offspring moving away from their parents. This prevents the offspring from competing with the parents for resources such as light or water. For example, dandelion seeds have “parachutes.” They allow the wind to carry the seeds far from the parents

O A. A is better because it has more surface area.
The question is incomplete and the diagram is also not given. So the diagram is attached below and the complete question is as follows:
The following models show one large cell (A) and four small cells (B).
Which of the following states why one of the models is better for moving more nutrients in and out of the cell?
A. B is better because it has more surface area.
B. A is better because it has less surface area.
C. A is better because it has more volume.
D. B is better because it has more volume
Answer:
A. B is better because it has more surface area.
Explanation:
The movement of nutrients in a cell depends on the surface to volume ratio. More is the surface to volume ratio, better will be the movement of nutrients in and out of the cell.
In the given model, small cells (B) has more surface to volume ratio as surface area of B is larger, so, the model B is better for moving more nutrients in and out of the cell.
Hence, the correct option is "A".
Answer:
B has smaller cells but more surface area than A
Explanation:
B
Hypoxia induces transcription of a DNA methyltransferase, DNMT1. What does this suggest about the relationship between hypoxia and regulation of gene expression
Answer:
Hypoxia is defined as an inherent condition of tumors that causes cancer development.
Hypoxia induces transcription of DNA methyltransferase, DNMT1 which suggest that hypoxia and regulation of gene expression have epigenetic relationship that refers to inheritable mechanisms responsible for regulating gene expression without altering the sequence of DNA bases.
DNA methylation is main epigenetic mechanism of Hypoxia.
Briefly explain what was done in the experiment where pigeons could choose which button to peck in the Skinner box. How does this relate to self-control?
In this experiment, Skinner placed a pigeon inside a box that contained a button that when pressed released water or food. This pigeon went through periods of deprivation of water and food, but over time, he realized that when he pecked the button he had access to these two elements. Skinner called this behavior operant behavior, which is the behavior that occurs controlled by its consequences.
Although Skinner did not specifically study self-control, with this experiment, we can make a connection between operant behavior and self-control, since both are behaviors shown as a way to change the environment in which they are inserted, but this change also affects them.
Compare and contrast the contributions of Neel, Pauling, and Ingram to our understanding of the genetic and molecular basis of sickle cell disease (SCD).
He demonstrated that SCD and sickle cell trait were due to the presence of abnormal 8-globin polypeptides in red blood cells. He demonstrated that the electrophhoretic mobility of B-globin from patients with SCD was different from that of healthy individuals. He demonstrated that both parents of multiple patients with SCD had low levels of sickled red blood cells. He hypothesized that SCD was a recessive trait and that the parents of patients with SCD would be heterozygous carriers. He demonstrated that the difference between B-globin polypeptides in individuals who were healthy and those with SCD is an amino acid substitution. He performed a peptide fingerprint analysis on B-globin from individuals with 84 84 and 89 88, which identified the segment of B-globin that was changed by the BS mutation.

If a small drop of tiny particles such as pollen grains are dropped into a drop of water on a microscope slide, they will appear to vibrate and spread out. The primary reason for this is
Answer:
The primary reason is that the pollen grains are being struck by water molecules that move in different directions. These strikes fluctuate and sometimes are uneven.
Explanation:
This vibration and spread out of molecules in water is called Brownian Motion. It is the result of the collision of small particles of water with big particles of pollen. As the particles of water move randomly hitting different sides of the pollen particle, at times, there will not be a coordinated movement, but as the movement of water particles is random, there will be moments when one side of the pollen particle will collide with more water particles, when this happens there is an unbalanced force that makes the pollen particle moves in a direction.
Place in correct order the following steps in the process of appositional growth of cartilage. a: New matrix is produced and secreted. b: Chondrocytes differentiate, each in its own lacuna. c: Stem cells undergo mitosis. d: Committed cells differentiate into chondroblasts.
Answer:
c: stem cells mitosis stem.
d: the compromised cells differentiate into chondroblasts.
a: New matrix is produced and secreted.
b: Chondrocytes differ, each in its own gap.
Explanation:
The appositional growth of cartilage occurs in an appositional order, thus generating these cartilage structures to give future bone structures or mature cartilages themselves.
In the cartilage of growth of long bones this process happens.
Chondroblasts are differentiated cells that can form the extracellular matrix, and chondrocytes would be the mature form of these that are submerged in their MEC once they reach the secretion limit.
The constant cartilage of cellular, mineral and organic structures, with organic compounds predominating (almost 80 percent are collagen fibers, proteoglycans and glycoproteins), that is why this tissue has a certain elasticity.

The muscle that originates on the sacrum and transverse process of each vertebra and inserts on the spinous process of the third or fourth more superior vertebra is the ________ muscle.
Answer:
The muscle that originates on the sacrum and transverse process of each vertebra and inserts on the spinous process of the third or fourth more superior vertebra is the Longissimus muscle
Explanation:
The Longissimus is a group made of three muscles: longissimus capitis, longissimus cervicis and longissimus thoracis. It has the length of the vertebral column.
It is placed in the back, and as the statement says, it originates on the sacrum and transverse of each vertebra. Each of them originates at the transverse elements and insert in the costal ones.
How do the products of meiosis compare to the original cell?
Answer:
Meiosis is the type of cell division in which a parent cell divides into four daughter cells. Meiosis generally occurs in the gamete or sex cells. The haploid cells are produced by the meiosis.
The original cell is diploid that contains the chromosome number (2X). The original is divided into the four daughter cell. The daughter cells produced by the meiosis contains the half chromosome number as compared with original cell (X). The crossing over occurs in meiosis and the daughter cells are quite different from the original cells.
Explanation:
Coal and petroleum products (fossil fuels) are a powerful resource of ___________ and energy. Following _________ plants and animals are buried and "stored" underground for millions of years leading to the formation of these byproducts.
Answer:
Carbon AND
DEATH
Explanation:
Carbon containing organic molecules derived from the remains of dead plants and animals on the earth million of years ago, buried deep under the sediment and rock layers are called Fossil fuels. Coal,oil,and natural gas are examples.
These underground deposits were formed million of years ago,due to the chemical reactions between relatively underground water molecules on one hand,and the earliest mic organisms viz algae,bacteria which inhabited the earth other hand.These decomposition occurred around 540 to 65milion years ago.
However,some million of later chemical reactions in the soil leads to compression of these remains underground.The degradation leads to formation of the fossil fuel precursor called Kerogen. With time Geothermal heat transforms the kerogen precursor to fossil fuel. some other kerogens are transformed to other natural gas,coal etc.
