Natural selection is an example of a mechanism of evolution. does this mechanism produce a change in individuals or populations? explain!

Yes, natural selection does produce a change in individuals as well as populations.

Explanation:

Natural selection is a process through which mother nature screens for the organisms that are best adapted to survive in a habitat. The theory of natural selection suggests that with time the organisms acquire those characteristics from their ancestors which allow them to be better adapted to a habitat. The other characteristics which are not needed to get extinct over a period of time. Hence, evolution changes individuals as well as populations.      

a. suckling by young

b. hypothalamus

c. dopamine

d. trh

e. anterior pituitary

f. mammary glands

g. milk production

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.
