What is the difference between a species and a population? a species includes only one type of organism, while a population includes many types of different organisms. a species includes only organisms that can reproduce together, while a population includes groups of organisms that cannot all reproduce together. organisms of the same species must live in similar climates, while organisms of the same population can live in different ecosystems with different climates. organisms of the same species can live in different areas, while organisms of the same population live in only one area.

What do nitrifying bacteria convert

If a strand of dna has 35% thymine. what is the percentage of cytosine, adenine, guanine?

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).
