Which of the following actions involves voluntary muscle movement?
Answer:
what are the options?
Explanation:
Voluntary muscles require a lot more energy than involuntary muscles and remain relaxed when you're not moving, such as when you're asleep.
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
In imaginary fruit, white fruit color (W) is dominant over yellow fruit color (w) and disk-shaped fruit (D) is dominant over sphere-shaped fruit (d). If a plant true-breeding for white, disk-shaped fruit is crossed with a plant true-breeding for yellow, sphere-shaped fruit, what will the phenotypic ratios be for: Show all work
Answer:
See the answer below
Explanation:
Genotype of a true-breeding white, disk-shaped fruit = WWDD
Genotype of a true-breeding yellow, sphere-shaped fruit = wwdd
Crossing the two:
WWDD x wwdd
WwDd
All the offspring (100%) will have the genotype WwDd with white, disk-shaped phenotype.
Assuming the cross is advanced to F2:
WwDd x WwDd
W_D_ 9 White, disk-shaped (9/16)
W_dd 3 White, sphere-shaped (3/16)
wwD_ 3 Yellow, disk-shaped (3/16)
wwdd 1 Yellow, sphere-shaped (1/16)

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.

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

What should you tell her?Do you think it is a good option for her?What has research shown out black as a preventive treatment for diabities?where could she find evidence based information about this?
Answer:
You should be advised to use it as a complementary natural treatment in addition to insulin or oral hypoglycemic, since it must be based on quality scientific evidence.
For this you can search in search sources such as PUBMED.
Explanation:
Some research maintains that black tea is responsible for stimulating the secretion of insulin by the beta cells of the pancreas
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.
Mitochondrion; crista Mitochondrion; crista Mitochondrion is a constituent part of crista. Crista is a constituent part of mitochondrion. Mitochondrion and crista are separate structures with no particular relationship to each other.
1. Mitochondrion; crista:
a. Mitochondrion is a constituent part of crista.
b. Crista is s constituent part of mitochondrion.
c. Mitochondrion and crista are separate structures with no particular relationship to each other.
2. Gobi complex; nucleus
a. Goo complex is a constituent part of nucleus.
b. Nucleus is e constituent part of Gobi complex.
c. Goo complex and nucleus are separate structures with no particular relationship to each other.
Answer:
1. b. Crista is s constituent part of mitochondrion.
2. c. Gobi complex and nucleus are separate structures with no particular relationship to each other.
Explanation:
The crista is an integral part of the mitochondria. As you already know, mitochondria is a cytoplasmic organelle. it has two members that delimit it, the outer membrane is completely smooth, however the inner membrane is composed of numerous folds, that are called crista, and that spread through the interior of the mitochondria. These crista have as main function to increase the surface of the inner membrane.
The Golgi complex is a cytoplasmic organelle, as is mitochondria. The nucleus, however, is a cell structure, it is totally separated from the golgi complex and there is no particular relationship between these two structures.
The golgi complex participates in the storage and distribution of substances in the cell, while the nucleus is responsible for housing and protecting genetic information.
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.
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%

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.

A cylinder at left with balls evenly spaced throughout the cylinder has an arrow leading to a cylinder at right cylinder with balls stacked near its bottom. How is energy related to the change of state represented by the model? Atoms gain energy as a gas changes to a solid. Atoms gain energy as a gas changes to a liquid. Atoms lose energy as a gas changes to a solid. Atoms lose energy as a gas changes to a liquid.
Answer:
C. Atoms lose energy as a gas changes to a solid.
Explanation:
Physical changes of matter take place by adding or removing energy from the matter.
In the given images, The left cylindrical is showing gas phase while the right cylindrical is showing a solid phase.
The process of conversion of gas into solid is called deposition. Deposition process takes place when atoms lose their energy and have high kinetic energy so they directly convert into solid and not into liquid.
Hence, the correct option is "C".

History has demonstrated that the techniques employed in this laboratory exercise often overestimate an individual's actual resting tidal volume. List some reasons why these laboratory techniques might produce abnormally high values for resting tidal volume.
Answer:
See below
Explanation:
One possible reason here could be the fact that since the person is being watched while doing this exercise, they might tend to breather deeper than they normally do. Secondly, it may also be because the person is trying to make up for the spit filter and flow meter by breathing harder/sharper than they normally would.
Adaptive immunity comprises two branches: humoral immunity and cellular immunity. What are the characteristics of each of the two arms of the adaptive defense system
Answer:
Adaptive or acquired immunity is that we acquire throughout our lives through vaccines (active), breast milk (passive) or injection of specific artificial or natural antibodies to a certain pathogen (passive).
The two great arms of this immunity are the humoral and the cellular.
The humoral refers to the cytokines and immunomodulatory molecules that are responsible for transmitting fundamental messages between defense cells in order to coordinate the destruction of the pathogen between them.
Instead, cellular immunity speaks about cell lineage such as b, t, tcd4 lymphocytes, natural killers, plasmacytes, etc.
It can be said that the humoral factor is the one that coordinates the pathways and the relationships between the cells of the acquired immunity, both are important because the two need each other for adaptive immunity to work.
Explanation:
Examples of the humoral factor: pro and anti inflammatory cytokines, interleukins, complement chain, antibodies, TNF alpha, beta, etc.
Examples of cellular factor: plasmacyst, b lymphocyte, t lymphocyte, NT lymphocyte
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.

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.
