Each cell only expresses a small portion of its genes at any given time. Not synthesizing unused proteins allows resources and energy to be conserved. This understanding best supports which of the following statements? Cells randomly express different genes
Gene expression is a regulated process
Cells cannot express certain genes
Unexpressed genes are never useful

(B)-Gene exspression is a regulated process

Explanation:

Its right I just took a test on it.

answer:

sequence 1- deletion

                  2- duplication

                  3- insertion

                  4- substitute

                  5- inversion

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
