A snow crystal appears when water vapor in the air converts directly into ice without first becoming liquid water. ... The exact shape of the final snow crystal is determined by the precise path it took through the clouds. But the six arms all took the same path, and so each experienced the same changes at the same times.
Answer: D
Explanation:
Nothing is stopping the population
Convection is a type of heat transfer that occurs
in molecules. It refers to the collective movement of molecules within fluids
and rheids (non-molten solids). Convection happens through the process of
diffusion, advection, or the combination of both. Therefore solids cannot
undergo this process because bulk current flows and significant diffusion
cannot take place within the molecules of solids. Aside from this, solids have
bigger molecules that are too compact and cannot move freely unlike fluids do.

Convection can best be seen through an experiment
when a glass of water is exposed to a heat source. The change in temperature in
the glass causes warm fluid to move into cooler areas which causes it to boil
and bubble. </span>

Secretion hormone stimulates the release of pancreatic fluid.
Explanation:
Secretion is a digestive hormone secreted by the duodenum(upper part of small intestine) that stimulates the release pancreas fluid and regulates the water homeostasis thought out the body and around duodenum. Its also regulates pancreas, liver and stomach secretions.
