specific macrophage populations promote both cardiac scar deposition and subsequent resolution in adult zebrafish
vova2212 [387]

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.

TWENTY FIVE POINTS!! What do the variables in the Hardy-Weinberg equation represent? Match the tiles.
Tomtit [17]

The Hardy-Weinberg principle is used to characterize the distribution of the different genotype frequencies in a population which are not evolving. In the Hardy-Weinberg equation,

the frequency of the homozygous dominant genotype is denoted by p^{2};

the frequency of the homozygous recessive genotype is denoted by q^{2};

the frequency of the heterozygous genotype is denoted by 2pq;

the frequency of the recessive allele is denoted by q;

the frequency of the dominant allele is denoted by p.
