Answer:
B. R is dominant to r, and Rr individuals are red.
Explanation:
In genetics the dominant allele is represented by the uppercase letter and the recessive allele is represented by the lower case letter. A dominant allele always shows its dominance over the recessive allele. So in heterozygous condition dominant allele will reflects itself in the phenotype.
Here allele of red color allele is in capital letter and alleles of green color are shown in lower case which means R allele is the dominant allele and r is the recessive allele. Therefore R is dominant to r and in homozygous condition(Rr) red individual will be formed. So the right answer is B.
Explanation:
The collaboration of human beings began in the past especially to offer security for offspring. Families living in communities had prolonged life for offspring due to collective security for the benefit of the whole community. Even when some members of community went to hunt or gather food, they are assured to the security of their offspring living in the community. It is believed it is such acts of collaboration that evolved into the current social fabric of society.

Specific macrophage populations help by promoting both cardiac scar deposition and subsequent resolution in adult zebrafish. It is a correct statement.
<h3>What is the effect of macrophages on zebrafish?</h3>
There is an inflammatory response to tissue injury. It is an important part of the process of repair. Scar tissue deposition is a direct downstream consequence of this kind of response in several tissues including the heart tissue.
Adult zebrafish do not only have the ability to regenerate lost cardiomyocytes. They can also remodel and resolve a scar which is extracellular, in tissues like the heart. This resolution of the scar is a poorly understood process.
Therefore, specific macrophage populations help by promoting both cardiac scar deposition and subsequent resolution in adult zebrafish.
