Explanation:
Nuclear fusion is a process in which two small nuclei combine together to result in the formation of a larger nuclei.
In Sun, the first step of hydrogen fusion includes combining of two hydrogen nuclei to result in the formation of a deuterium, positron and neutrino.
The nuclear fusion reaction inside the sun is as follows.
Thus, we can conclude that products of step 1 of the hydrogen fusion process in the Sun are isotope of hydrogen, a neutrino, and a positron.
The directional selection is the type of natural selection, in which an extreme phenotype is promoted due to the changes in the environment. This causes the changes in the allele frequency and the shifting of the phenotype in a particular direction. In this condition, one of the extreme phenotypes are promoted, which result in the shifting of genotypic frequency either of the homozygous characteristics.
Glucose is different from glycogen as Glucose is used immediately for energy in the cell while glycogen is stored in the liver for later use as energy. Thus, the correct option is A.
<h3>What is Glycogen?</h3>
Glycogen may be defined as the reserved form of glucose that is constructed up of many interconnected glucose molecules.
When the cell needs immediate energy to accomplish metabolism, they directly use glucose for it, but while energy is not needed by the cell, then glucose is stored in the liver and muscles in the form of glycogen.
Therefore, Glucose is different from glycogen as Glucose is used immediately for energy in the cell while glycogen is stored in the liver for later use as energy. Thus, the correct option is A.

Answer:
Parasites are organisms that infect the body of another living being and live off their hosts to survive. While some parasites create no symptoms in their hosts, others can cause severe illness. Parasitic infections occur when parasites grow, reproduce, or invade organ systems that make their hosts ill.
