C. Nucleic Acids arranged in a double helix.
Explanation:
The structure of DNA is best described as a double helix. DNA has a sugar phosphate back and nucleotides connected by covalent bonds. Together, it looks like a twisted ladder which is also known the double helix.
Answer:
b. False
Explanation:
Angina pectoris is the medical term for chest pain that results from coronary heart disease.
It occurs when the heart muscle doesn't get as much blood as it needs and is usually caused by the accumulation of plaque on the inner walls of the heart’s arteries.
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.

NO, the ocean is salty because it is the place where many of the salt from lakes and rivers leave off in. If this doesn't happen, then there will not be any fresh water, there will only be salty rivers, very salty rivers, not so salty rivers, or so salty to the point you can't even drink it salty water (lol)
hope this helps
