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.
Plants release oxygen into the atmosphere during photosynthesis while respiration by plants and animals and the decomposition and decay of dead organisms releases carbon dioxide into the atmosphere. These three produce maintain a cycle in which plants and animals depend on and benefit from each other.
