The compound action potential increases in amplitude with an increase in stimulation voltage is due to recruitment of small diameter axons followed by large diameter axons in the nerve.
what is axons?The part of a nerve cell (neuron) that transports nerve impulses away from the cell body is known as an axon. A neuron has one axon that connects it to other neurons, muscle cells, and gland cells.
What is compound action potential?Compound action potential measurement capabilities are built into cochlear implants and are used as objective measures during device setup and programming. Because the stimulus recruits many fibers simultaneously and synchronously, the response is called a compound action potential because it is the sum of the many potentials recruited.
The amplitude of the reaction is increased via summation and synchronous production, making detection possible. A variety of diagnostic methods include recording the electrical activity of peripheral nerve neurons. A second deflection will emerge in the displayed waveform when we gradually increase the stimulus voltage using the control knob on the stimulator.
hence, the correct answer is B.

7. Shawn plotted the data in a bar graph with two bars: one representing the number of bees per colony in the control cages and the other representing the number of bees per colony in the cages exposed to the fungicide. If the results support the hypothesis that fungicides harm bee development, what would you expect this bar graph to show? Describe the expected pattern in a few sentences.
Answer:
The first bar increases in length as compared to the second bar.
Explanation:
The length of the bar of control cages in graph increases because the number of bees per colony increases while on the other hand, the length of the bar of the cage that is exposed to fungicides decreases because the bees are negatively affected from the application of fungicides. They act abnormal in behaviour and adversely affected the reproduction of bees that greatly affected its population.

Solve the equation of mava=mbvb max5.0ml=5.2mlx0.10m
Answer:
0.104M
Explanation:
The following equation is given in this question:
mava=mbvb
Where;
ma = molarity of acid (M)
mb = molarity of base (M)
va = volume of acid (ml)
vb = volume of base (ml)
According to this inputted values;
max5.0ml=5.2mlx0.10m
ma = unknown molarity of acid
mb = 0.10M
va = 5.0ml
vb = 5.2ml

A degraded ecosystem is replaced with a different but productive ecosystem type, one that might even include some nonnative species. For example, a degraded forest might be replaced with a productive pasture.a. passive restoration b. remediation c. partial restoration d. rehabilitation e. complete restoration
Answer:
d. rehabilitation
Explanation:
Technology-associated rehabilitation is an ecological practice that allows a degraded area to be restored, rehabilitating all its degraded habitats. However, this restoration is not done naturally, but is caused by human intervention, which can cultivate the entire plant population in the area, even adding non-native species, which are selected to leave the productive area, but ecologically harmonious.

how is the oxygen cycle disturbed by deforestation
Answer:
If deforestation is disturbed then the photosynthesis cycle is disturbed, which results in the oxygen cycle being affected. With a decrease in trees, a decrease in photosynthesis occurs, which cause a decline in the oxygen cycle. A decline in the oxygen cycle results in more polluted air.
Explanation:
Without trees, humans would not be able survive because the air would be unsuitable for breathing. Due to deforestation, there would be fewer trees to "clean" the air. Deforestation is the action or process of clearing of forests, or the state of having been cleared of forests.
Trees and plants, in general, produce energy for growth using a process known as photosynthesis. Using light, water and carbon dioxide, a plant produces energy in the form of sugar and releases oxygen into the air.
Deforestation, as well as a rise in the emissions and our global temperature, affects the air that we breathe. This is because all trees take in carbon dioxide and other pollutants which are known to cause a lot of problems in the atmosphere and to humans. This inevitably results in people breathing dirtier and more polluted air that normally wouldn't happen.
Long-term exposure to polluted air can have permanent health effects such as: Accelerated aging of the lungs. Loss of lung capacity and decreased lung function. Development of diseases such as asthma, bronchitis, emphysema, and possibly cancer.
Trees are responsible for taking the carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly higher amounts of carbon dioxide in the air and lower amounts of oxygen. This bad quality air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide.
In addition to the decrease of oxygen in the atmosphere, it would allow excessive amounts of carbon dioxide to remain. In the short term, since CO2 is one of the major greenhouse gases, it will undoubtedly lead to higher global temperatures which, in turn, would quicken the melting of the polar ice caps.

Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.
Answer:
The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.
Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.
Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.

What is the principle of size exclusion chromatography?
Answer:
The underlying principle of SEC is that particles of different sizes elute (filter) through a stationary phase at different rates. This results in the separation of a solution of particles based on size.
hope it helped
Size exclusion chromatography (SEC) separates molecules based on their size by filtration through a gel.
What is size exclusion chromatography?
Size exclusion chromatography (SEC) splits molecules based on their size by filtration via a gel. The gel consists of spherical beads including pores of specific size distribution. Separation happens when molecules of various sizes exist included or excluded from the pores within the matrix.
Size exclusion chromatography exists named gel filtration chromatography because the gel effectively allows for the filtering of molecules from a sample based on molecular size. However, unlike other methods, the larger molecules elute first.
Size-exclusion chromatography (SEC), also understood as molecular sieve chromatography, exists a chromatographic procedure in which molecules in solution exist separated by their size, and in some cases molecular weight. It exists usually applied to large molecules or macro molecular complexes such as proteins and industrial polymers.

Answer:
A yellow lizard population living on an island with no predatorsA hawk was introduced to the habitat and starts preying on the yellow lizard because it is easier to see from the air Some of the lizards mutate their color from yellow to greyish brown so they can camouflageYellow individuals keep being hunted, while brown individuals get to survive The following generations of lizards will have a higher proportion of greyish brown individuals and just a few yellow individuals. Eventually, almost all of the lizards will be greyish brown individuals.Explanation:
The scenario is the following.
A population of yellow lizards lives on an island where there is no natural predator. Males of the species use the yellow color to attract females in reproductive seasons. The brighter the males are, the better their genetic quality is. Females are also yellow, but not as bright as males.
A new hawk species was introduced into the island to control some farm pests. But this hawk species prefer to feed on the lizards. The yellow color of these animals contrasts with the dark background and can be easily seen from the air. So the lizard population suffers from significant predation affecting its size sharply.
Some of the lizards then suffer from a mutation and change their color from yellow to greyish brown, which turns to be better to camouflage on the rocks and get to survive. Individuals with greyish brown color get to reproduce at a higher rate than yellow individuals, who keep being hunted by the hawk.
Eventually, after many generations, the yellow individuals decrease to near zero in the population, while greyish brown individuals increase significantly, with males still being brighter than females.
------------------------------------------------------------------------------------------------------
Natural selection is an evolutive force that can act favoring an allele or against it, according to how it affects the fitness of individuals. Natural selection selects beneficial alleles and increases their frequency in the population.
When many organisms in a population sharing the same trait die, it is because they did not have good fitness, so they were not adapted to the environment and its pressures. The alleles coding for that trait were not good for the fitness of the animals, so they do not get to survive.
These individuals die before reproducing, so they could not transfer their genetic charge to the following generation. Eventually, the alleles coding for the trait will decrease in the population, probably near zero. Natural selection is acting against this phenotype. Other alleles will be beneficiated, and their frequency in the population will increase.
This change in alleles frequency is what we call adaptation.
Natural selection results in adaptation, which means the increase of the aptitude phenotype. Aptitude is the contribution of each genotype to the next generation.
In many cases, adaptations can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
Let us remember that a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
So, in the exposed example, we are focussing on the lizards population.
• The selective pressure or modeling environmental factor is predation by the introduced hawk.
• The lizards´ response to predation is the survival of only those that carry mutations ⇒ greyish brown color
• Natural selection benefits these mutations.
• Greyish brown lizards survive and increase their fitness.

If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, will an action potential be produced?
Answer:
Yes
Explanation:
If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, the action potential will be produced. In a chemical synapse, an action potential in the presynaptic neuron is responsible for the release of a chemical messenger known as neurotransmitter. After this, the neurotransmitter diffuses across the synapse and binds to the postsynaptic cell so we can say that potential can be produced.
