Biology
1 answer:
Drupady [299]3 years ago

Answer:

It's important for a scientist to try to hold all variables constant except for the independent variable.

Explain the role of insulin in the homeostatic regulation of blood glucose levels
Xelga [282]

Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
