Answer 13

STIMULATED

Question 14

Growth hormone carries out its direct actions by binding to receptors in some tissues, such as the liver, adipose tissue, and skeletal muscle.

Answer 14

Tyrosine kinases associated receptors

Question 15

Somatostatin is a (stimulatory/inhibitory) factor of growth hormone.

Answer 15

Inhibitory
