The relationship below explains a type of symbiosis. read the paragraph, and then answer the questions that follow.

a clown fish lives in and around the sea anemone. the clown fish has a protective mucous coating, which prevents it from being stung by the sea anemone. since the clown fish can not be harmed by the anemone, it gains protection by living in and around the anemone. the clown fish will in return ward off any predators of the anemone to protect it's home.

a. what is symbiosis?

b. what type of symbiosis is this example? explain why.

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).
