Answer:
C. Characters with little genetic variation will constrain the rate of natural selection
Explanation:
Natural selection can have an effect only as long as there are variations on characters on which it can select upon. Genetic variation is independent of the environment or the needs that a species may have to become better adapted to its changing environment. In other words, genetic mutations are the raw material on which natural selection can work. If there is a low rate for mutations to occur, then natural selection will proceed at a slow pace. The opposite is also true. Since mutation rate may be more frequent at some locations in a gene than at others, it can be predicted that the characters coded in that gene location will be more likely to be affected by natural selection and therefore what phenotype may be molded by natural selection.
The answer for this will be C an integration of organ systems this is because the endocrine system also works with the nervous system and immune system etc
C3H2H4- Imidazole-Organic compound
AlBr3-Aluminium bromide- Inorganic
C6H5F-Fluorobenezene-Organic
Cro3-chromic acid-Inorganic
H2O2-Hydrogen peroxide-Inorganic
C12H22O11-Sucrose- organic
Basically when a compound contains carbon atom in it its said to be organic.
<span>d. neither of these will cross a plasma membrane.
Glucose cannot diffuse across a plasma membrane as it is polar. Since the question doesn't specify the type of diffusion, simple diffusion is assumed.
If you count facilitated diffusion, then A is the answer.</span>
