Based on the illustration, what happens to most of the mass gained by the plant cell through photosynthesis? a) the mass is returned to the soil. b) the reactants of photosynthesis are used as the reactants of respiration. c) the products of photosynthesis are shuttled back into the photosynthesis reaction as reactants. d) the mass produced by the photosynthesis reaction is used by the plant to fuel respiration and is turned into carbon dioxide, water, and energy.

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.
