Answer:
The answer is C.
A 5 percent increase in the reproductive success of some genotypes, but a 5 percent decrease in the reproductive success of other genotypes

Incomplete question, here is the full question: https://quizlet.com/153540854/biology-107-part1-flash-cards/
For the genetic structure of a population to change, we can either depend on natural selection or mutations but there has to be an imbalance.
The answers given in the options A and B are referring to changes in genotypes which surely affects the genetic structure of the population but the way these options are given is in equilibrium, meaning they create and imbalance but then counter that with something else.
In option C, some genotypes get a 5 percent increase while some get a 5 percent decrease in their reproductive success, which will most likely result in a change in the genetic structure of a population.
I hope this answer helps.
Answer:
a) Ribosomes
b) Please find the justification for the answer in (a) below.
Explanation:
According to this question, Hepatitis C is a virus that causes liver disease by attacking the liver. However, a REDUCTION IN ALBUMIN, which is a protein that regulates oncotic pressure of blood in humans- a process necessary for the regulation of fluids in vessels of the body and tissue repair, has been found to have to do with liver disease.
Since ALBUMIN is a protein produced by the liver, which when diseased causes a reduction to the blood-albumin level, the organelle in liver cells that is most likely being affected by hepatitis C is the RIBOSOME. This is because the RIBOSOME is the organelle/site for PROTEIN SYNTHESIS in any cell. Hence, the ribosome organelle of the liver cells are responsible for synthesis of Albumin protein.
Hence, a diseased liver due to attack by Hepatitis C virus means an attack on the RIBOSOMES of the liver cells producing the protein.
Answer:
Option-E
Explanation:
The phospholipid bilayer is the layer which forms the outer membrane of the cell.
The phospholipid layer is amphipathic as it contains both the hydrophilic and hydrophobic portions.
The phospholipid is composed of the glycerol attached to phosphate groups which form head or hydrophilic region and the 3 fatty acid tails which form the hydrophobic portion.
The head or hydrophilic portion is arranged in the layer facing the outer external portions and the inside of the cytoplasm as the lipid layer exist in the bilayer.
Thus, Option-E is correct.
Receptors within the highlighted area provide the sense of HEARING.
The highlighted section of the ear is the organ of Corti. The organ of corti is the sensory receptor inside the cochlea, which holds the hair cells, which are the nerve receptors for hearing.
