CRISPR can be used in several ways to develop pigs for human transplant organs. In – , CRISPR can be used to allow pig organs to be transplanted. CRISPR must be used to mutate – genes and to manipulate production of – system proteins to avoid rejection. Another method uses CRISPR to grow human organs in pigs by first deleting genes that normally stimulate – and then inserting human – into the resulting pig embryo, allowing a pig to grow a human organ.

Epinephrine is a hormone released from the adrenal gland of the body, most often in a stressful situation. it is known as the "fight-or-flight" hormone. one way that it causes a response in the body is to activate receptors on muscle cells. where are these cellular receptors located? a. on the cell membrane b. in the nucleus c. on the cell wall d. around the mitochondria

Do you think the gene eef1 alpha1 supports cell theory? explain your response.
