Describe how the food molecules that an organism eats can become part of that organism??

food molecules become digested once there is a concentration gradient to drive diffusion, the nutrients need a path across the membrane. fats and fat soluble nutrients can move directly across the lipid membrane. water, gasses ane other very small molecules can diffuse through the pores of the cell.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion
