Which of the following statements is supported by the information in the diagram?

A:The light mice are poorly adapted to survive in any environment. Because of this, fewer light mice were able to pass on their genes.

B:The dark mice all have identical genes. Because
f this, the dark mice were more likely to have a beneficial mutation and pass on their genes.

C:The dark mice are hard to be seen against the dark rocks. Because of this, the dark mice lived to reproduction age and produced more dark mice.

D:There are more light mice to begin with, making it hard for them to compete for resources. Because of this, there were fewer light mice in the next generation

One gene can influence trait(s). one trait can be determined by gene(s).

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).

What are antigens and antibodies? how are they involved in the body’s response to incompatible blood?
