Question 1: In terms of NPP, which three biomes contain the least complicated interactions within food webs and nutrient cycling and what factors (temperature, rainfall or nutrients) limit the productivity of these biomes? Question 2: What implications do these data have for agricultural practices in different parts of the world (i. e. an area of rainforest is converted to farmland)?

In familial hypercholesterolemia individuals homozygous for the allele causing the disorder completely lack receptors on liver cells that take up cholesterol from the blood stream. heterozygous have one-half the number of receptors while individuals homozygous for the normal allele are phenotypically normal. this is an example of a.epistasis b.complete dominance c. incomplete dominance d. codominance

Animal bodies (and even plant bodies for that matter) are complex enough that life couldn't exist without enzymes. enzymes are usually large, complex biological catalysts that are expensive to make. enzymes speed up the rate of chemical reactions without being used up during the reaction (they can be reused many times). they are highly specific in the reactions they regulate. knowing what enzymes are and how they function, why does this explain why complex life forms could not exist if there were no enzymes.

A(n) is a molecule influences the way that a molecule reacts.
