Answer:
A. Accurate but not precise
Step-by-step explanation:
The illustration given shows that the was far from each other which means it is not precise because precision is that the given data must be close to each other. However, it is accurate because the darts are closer to the bullseye which can still be considered as accurate. Therefore, I believe this is accurate but not precise.
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.

Answer:
'Cross experiments done by Morgan, illustrating the X-inheritance link of a mutation Thomas Hunt Morgan moved intensely in a program of breeding and crossing miles of fruit flies at New York University in a room that was renamed the Fourth of the Flies. He tried to mutate the flies with various means (X-rays, centrifuges, etc.) .The fruit fly which has 4 pairs of chromosomes. One of those pairs was identified as containing X and Y sex chromosomes. He applied Mendelian principles in flies. Morgan's inheritance study demonstrated inheritance linked to sex, and is one of the first evidences that confirm the chromosomal theory of cross-based inheritance. In 1909, Morgan detected a fruit fly (Drosophila melanogaster) with a strange mutation which he called "white eyes", due to the coloration of his eyes (contrary to normal, which is red). Analyzing this fly under the microscope Morgan discovered that it was a male, and could use it as a stallion so that he could observe how the new characteristic of white eyes would pass from generation to generation.All the offspring of this cross will have red eyes, which He made Morgan suspect that something strange had happened, since the color of the father's eyes could not have disappeared. He decided to take a couple of "daughters flies" and cross them together, just to see what happened. Morgan's surprise was very great, observing that among the "granddaughters" flies only males had white eyes. The problem then was to explain what had happened during the hereditary transmission for the color of the white eyes only the males possessed. .
molecules will gain energy, causing them to move faster and spread further from each other
