Suppose that the number of newborns (n) in an insect population can be predicted from the number of adult insects (i) according to the following equation, where r and b are variables related to the rates of population growth: n=ri−bi2. calculate n if r=1.5, b=0.0015, and i=500. rounding to the nearest whole number, n equals which of the following?

a. 1880
b. 375
c. 188
d. 749

Which macromolecules are polymers made of nucleotides (a) fatty acids (b) nucleic acids (c) carboxylic acids (d) amino acides

True or false most plants are c3 plants, because they use molecules of carbohydrate known as g3p in their photosynthesis process.

Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.
