Answer:
The correct answer is - Honeycreepers arose from a single species that migrated to Hawaii and adapted to different niches over time.
Explanation:
All Hawaiian honeycreeper bird species share similar muscle and skeletal structures. This suggests that all Hawaiian bird species arose from a common ancestor and evolved due to different environmental conditions such as eating particular foods for particular species.
It is believed to be a single species of honeycreeper who migrated from the mainland to Hawaiin island and adapted to different niches over time by the process known as natural selection.
Answer:
Glucagon.
The receptor has seven transmembrane a helics secreted by pancreatic a cells.
Polypeptide.
Stimulate glycolysis and glycogenesis in the liver.
EPINEPHRINE.
Stimulated muscles cell to breakdown glucogen.
Amino acid derivative.
Released in response to stress.
EPINEPHRINE AND GLUCAGON.
Released in response to a drop in glucose levels.
Explanation:
Epinephrine is called adrenaline hormone, it is secreted by the medula of adrenal gland. It is an amino acid derivative, it stimulate muscles cells to breakdown glucogen. This hormone is released in response to body stress.
Glugagon is a peptide hormone that is secreted by alpa helics of pancreases. It prevent blood glucose from dropping. It stimulate the conversion of glucogen to glucose in the liver which is release to the blood stream.
The two hormones is released in response to drop in glucose levels to increase glucose concentration in the blood.
