hichkok12 [17]

Answer:

C. is unstable, with a short half life

Explanation:

Paracrine hormones are the hormones that act on neighboring cells only. These hormones or chemicals are largely unstable and have a brief life as do not visit the distantly placed target cells. For instance, somatostatin is secreted by D cells of the pancreas. It acts in a paracrine manner and inhibits the discharge of hormones from the neighboring beta and alpha cell.

Likewise, one of the functions of unstable NO gas is to serve as a vasodilator. It is released by epithelium cells and serves to dilate arterioles and relax precapillary sphincters. Then it is degraded.

Vika [28.1K]

Answer:

The correct option is C: "Oxygen levels would be higher, but carbon dioxide levels would be the same".

Explanation:

The sealed aquarium is paced near a window which means they have access to sunlight, and hence, can photosynthesize. As the plants use up carbon dioxide during the day and give out oxygen during this process, they also respire during the night, a product of which is carbon dioxide. This is why the levels of carbon dioxide will remain the same and level of oxygen will rise because they are photosynthesizing for a longer period during the day than they are respiring during the night.

Hope that answers the question, have a great day!
