Answer:
The theory of evolution basically serves to explain the biological evolution of living beings. The theory of evolution basically serves to explain the biological evolution of living beings. This results in the appearance of new species different from the previous ones.
Answer:
The correct answer is - natural selection process does not move simply to an optimized endpoint.
Explanation:
Natural selection is a process of evolution that helps in evolving populations that are adapted to successfully reproduce and survive according to the environment.
Natural selection does not march simply to an optimized endpoint. Natural selection works upon individual organisms that have advantageous characteristics in specific environments. If the environment changes the advantages can become disadvantageous.
Thus, the correct answer is - natural selection process does not move simply to an optimized endpoint.
The moon is abiotic because it is a non living thing
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.
