Explain how respiration occurs in plants. Someone please answer
Answer:
Respiration is the process includes plants,receive their energy for a chemical chain system is called respiration.
Explanation:
Respiration is the biochemical process , is the external environment the cell,special living a tissues.
Respiration is the process plants oxygen gas inhaled and the carbon gas exhaled out the plants.
During the respiration is the gas exchange process different parts of the plants:-ROOTS, STEMS, plants exchange respiration easily.
Roots are the underground part of the plant and present in the soil particles, and the night the respiration plants is prominent.
Respiration in stems air the diffused the various parts of the cell for passes respiration.

g The pH of the space between the inner and outer mitochondrial membrane is ______________ the pH of the mitochondrial matrix.
Answer:
lower than
Explanation:
The protons obtained from the spit of hydrogen atoms, to protons and electrons, (which was transported to the Matrix of the mitochondria by NADH and FADH2 ) are pumped by PMF into the intramembrane space.
The constant pumps by the PMF,due to the electron transport chains set up high concentration of Hydrogen ions in the intramembrane space.If pH is -log[H+] then the high the number of H+/protons,the stronger the acidity,and lower the pH of the medium.
This set up higher electrochemical gradient compare to the matrix.Thus H+ diffuses down the gradients into the matrix.
This generate energy needed for the synthesis of ATPs by ATPase synthase in the matrix
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.
The diagram shows animal and plant cells placed in 3 different types of solutions.
a) Name the 3 types of solutions taking inference from the picture above and explain the process taking place in A
b) When plant cell is placed in solution C, which part prevents it from bursting and how?
c) Name the process by which Amoeba obtains its food
This diagram shows vegetal and animal cells placed in solutions of different concentrations.
a)Solution A is called hypertonic because it has a higher concentration than the cell's cytoplasm. In the animal cell, it causes the water to diffuse out through osmosis. In the plant cell water is lost through the same process but the cell wall remains intact while the membrane reduces in volume.
Solution B is called isotonic because it has around the same concentration as the cytoplasm of the cell. It does not influence the volume of the cell.
Solution C is called hypotonic because it has a lower concentration than the cytoplasm. In the animal cell, it causes the cell to fill with water until it bursts(this process is called cytolysis). In the plant cell water diffuses through the membrane, but the cell doesn't burst.
b)Plant cells have a strong cell wall made of cellulose, hemicellulose and, lignin that prevents cytolysis.
c)Amoeba obtains its food through a process called phagocytosis in which the solid material is engulfed in a vesicle that enters the cell.
Plant cells have a strong cell wall made of cellulose, hemicellulose and, lignin that prevents cytolysis.
What do you mean by cytolysis?Cytolysis, or osmotic lysis, occurs when a cell bursts due to an osmotic imbalance that has caused excess water to diffuse into the cell. Water can enter the cell by diffusion through the cell membrane or through selective membrane.
Cytolysis or osmotic lysis occurs in animal cells and certain bacteria, especially when the cells are exposed to a hypotonic environment, causing the water to move into the cell, thereby increasing or expanding the cell.
When cells burst and die, their contents are released, causing inflammation. Every day, more than 50 billion cells die in our bodies. These are not random events, but part of a finely tuned biological mechanism called programmed cell death.

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.
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.
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.
Describe the flow of energy from a glucose molecule to ATP during respiration, and compare this to the flow of energy from glucose to acids and alcohols during fermentation. Specifically, what carries the energy from glucose to ATP - what energy conversions must occur during the process. Compare the ATP production during respiration with ATP production during fermentation.
Answer:
Glycolysis is the first step of the cellular respiration in an organism which is metabolic pathway that is completed in the cytosol of the cell that leads to the converting glucose to the pyruvate in order to produce energy in form of ATP:
1. Glucose-6-phosphate is ---> fructose-6-phosphate
2. fructose-6-phosphate ---> fructose-1,6-biphosphate
3. fructose-1,6-biphosphate ---> glyceraldehyde-3-phosphate(GAP) and dihydroxyacetone phosphate (DHAP).
4. GAP is oxidised ----> 3-bisphosphoglycerate + NADH
5. 3-bisphosphoglycerate ----> 1,3-bisphophoglycerat
6. 1,3-bisphophoglycerate ----> 3-phosphoglycerate
7. 3-phosphoglycerate ----> 2-phosphoglycerate
8. 2-phosphoglycerate ----> phosphoenolpyruvate (PEP)
9. phosphoenolpyruvate to ADP ----> pyruvic acid + ATP
Formation of ATP occurs in both pathways or process that are respiration and fermentation. Fermentation is a catabolic pathway leads to the degradation of sugars (partial) that result in the gain of energy and this energy are absorbed in ATP. There are difference of the amount of energy or ATP produce in these process in respiration 38 ATP are produced whereas during fermentation only 2 ATP are produced.
the white wallaby in this image has a mutition thatgives it a white colorng. how could this coloring affect its survival in its environment
Answer:
When changes happen in an environment. Many things can and will happen. If there was a gene mutation for the color of beetles, then that would affect their survival because the old color could have helped them hide and be camouflage. (however you spell it) If that is changed it could make them more out in the open, so predators could get them easier. Which would result in less beetles and more predators. Some examples are like the white wallaby, because of its environment it changes color to blend in and survive.
Explanation:
Posted on Brainly before.
When environmental changes occur. Many things are possible and will occur. The survival of beetles would be impacted if there was a gene mutation that changed their color because their previous color may have helped them blend in.
What white wallaby has a mutation that gives it a coloring?The population of white wallabies will become more vulnerable to predators as a result of a mutation that alters their color pattern, and as a result.
There will be a modest drop in the overall number of white wallabies in the environment. In other words, the mutation decreases their chances of surviving.
The young, known as joeys, are nurtured in a pouch by all wallabies, which are marsupials. Their tails, which are not prehensile or grasping like those of kangaroos, are long, strong, and useful for balance.
Long jumps can be made by wallabies using their robust hind legs. The feet of rock wallabies are uniquely adapted to help them grip the rocky environment in which they inhabit.
Therefore, As its name implies, Nail-tail Wallabies have a pointy growth at the end of their tails.

compare the innate and adaptive responses to repeated challenge with the same antigen by sketching the immune response curve over time
Answer:
Innate immunity is defined as the first line of defense against infections and faster than adaptive immunity while adaptive immunity is second or third line of defense mediated by the T and B lymphocytes.
Adaptive immunity forms memory cells for the same antigen while innate immunity do not.
As shown in the graph below, when an antigen enter in the body for the first time, our immune system response with innate immunity and response immediately with several symptoms such as sneezing, swelling or redness et-cetra. Then after few days adaptive immunity forms which is mediated by the T and B lymphocytes by forming against the antigen.
Now if the body exposed to the same antigen again (Secondary exposure), the immune system shows amplified response as it has already formed memory cells against the antigen.

The cardiac tissue has fewer T tubules and store less calcium than skeletal muscle. What is the outcome of these two traits
Answer:
The slow arrival of contraction or the slow onset of contraction.
Explanation:
The T tubules function in the transformation of the action potential from the sarcolemma to the sarcopasm reticulum.
In the skeletal muscles, it is located at the junction of the A and I bands but in the cardiac muscles, it is located only at the z discs thus giving rise to to T tubules.
The cardiac muscles also do not possess as much calcium as the skeletal muscles thus, its calcium ion must come from outside producing the slow arrival of contraction or the slow onset of contraction.
The cardiac tissue has fewer T tubules and stores less calcium than skeletal muscle, thereby the onset for muscle contraction is SLOWER in the heart than in skeletal muscle.
The sarcolemma is the plasma (excitable) membrane of muscle cells, which are surrounded by endomysial connective tissue.The T-tubules are invaginations of the sarcolemma that enter into the muscle cell in order to form interconnected networks.These tubules (T tubules) store intracellular calcium ions under the supervision of membrane depolarization through a voltage sensor channel (i.e., DHPR).In conclusion, the cardiac tissue has fewer T tubules and stores less calcium than skeletal muscle, thereby the onset for muscle contraction is SLOWER in the heart than in skeletal muscle.

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.

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.

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.
The cross AB/ab X ab/ab produces the following progeny: AB/ab 391, ab/ab 401, aB/ab 406, Ab/ab 386. From these data, one can conclude that the A and B loci assort independently.
A. True
B. False
Answer:
B
Explanation:
The two loci did not assort independently.
In order to check for independent assortment or otherwise of the result from the cross, Chi-square is used to see if the result conforms with that of Mendelian standard of 9:3:3:1.
Phenotype Observed f Expected f [tex]X^2[/tex] = [tex]\frac{(O - E)^2}{E}[/tex]
AB/ab 391 9/16 x 1584 = 891 [tex]\frac{(391-891)^2}{891}[/tex] = 280.58
ab/ab 401 3/16 x 1584 = 297 [tex]\frac{(401-297)^2}{297}[/tex] = 36.42
aB/ab 406 3/16 x 1584 = 297 [tex]\frac{(406-297)^2}{297}[/tex] = 40.00
Ab/ab 386 1/16 x 1584 = 99 [tex]\frac{(386-99)^2}{99}[/tex] = 832.01
Total [tex]X^2[/tex] = 280.58 + 36.42 + 40.00 + 832.01 = 1,189.01
Degree of freedom = 4 - 1 = 3
Tabulated [tex]X^2[/tex] at degree 3 freedom and 95% level = 7.815
The calculated [tex]X^2[/tex] value is more than the tabulated value. Therefore, we conclude that the outcome of the cross is not in agreement with Mendelian standard and hence, the A and B loci did not assort independently.
The correct option is B.
The medulla oblongs ya controls the contraction and relaxation of the blank causing the lungs to inflate and deflate during breathing.
Answer:
This question includes some errors, the question should be written as:
The medulla oblongata controls the contraction and relaxation of the ______ causing the lungs to inflate and deflate during breathing.
Although there are no options, the answer is generally RESPIRATORY MUSCLES i.e. diaphragm and intercostal muscles
Explanation:
Breathing is an involuntary action required to take place in order to get oxygen into the system and carbon dioxide out of the system. However, the process of breathing is neurally controlled by brain portion called RESPIRATORY CONTROL CENTERS.
The Medulla oblongata located in the hindbrain is one of the two respiratory control centers (the other being the PONS). The medulla sends nerve signals to the muscles responsible for bringing about the ventilation process i.e. the DIAPHRAGM and INTERCOSTAL MUSCLES.
This nerve impulse brings about the contraction of the diaphragm, which is the major respiratory muscle, and intercostal muscle causing the lungs to inflate and allow the entry of oxygen-containing air. On the other hand, it also brings about the relaxation of these muscles causing the lungs to deflate allowing the expelling of air.

Steroidal hormones enter the cell directly and interact with DNA inside the nucleus. These hormones change gene expression, affecting the RNA that is produced and the proteins that are translated in a cell. Nonsteroid hormones do not enter the cell. Instead, they bind to specific receptors on the outside of the cell membrane. This triggers molecules called secondary messengers, such as cAMP, to begin their work of relaying information in the cell, where other chemicals, messengers, and proteins are involved to create a cellular response.
