A small number of finches live in a protected bird area they are given as much food as a need to have and have plenty of space why would natural selection not occur in this population? A. There is not genetic variation in the finches B. The population has not reached carrying capacity C. There is not reason for genetic mutation to occur D. The birds compete for limited resources

the correct answer is:

a population changes in response to a change in the environment.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
