"<span>b. the liver is able to manufacture some amino acids from others."
The liver has the capability to transform some amino acids into others (called non-essential because they can be produced by the body and there is no need to get them from food). This is done by transamination.

The statement that best summarizes Darwin's theory of natural selection is D. Organisms best suited to their environment will survive and reproduce. This is becasue let's say some giraffes have short necks and some long necks and their food is leaves on high trees then the long necked giraffes will survive over short necked giraffes because short necked giraffes can't reach for their food and eventually there will be only long necked giraffes left and they will reproduce with other long necked giraffes and make long necked giraffes.
