Answer:
gain-of-function
Explanation:
Gain-of-function mutations represent a type of genetic change that may confer a new function to the gene that undergoes the mutation. In this case, a gain-of-function mutation conferred to the virus an adaptive advantage by allowing it to encode a new protein which is capable of attaching to the cell membrane of a new host. In this regard, it is important to note that loss-of-function mutations are quite common in nature, while gain-of-function mutations are relatively rare.
Answer: The correct answer is hormone
Explanation:
A hormone is a chemical substance produced by an organ (usually called gland) and on production is released directly into the bloodstream to be transported to another part of the body (usually called target organ) where its exert its function.
An example of hormone is thyroxine, it is produced by the thyroid gland in the neck and exert function on almost all cells of the body
Answer:
In incomplete dominance a heterozygous individual blends the two traits. ... With codominance you'll see both alleles showing their effects but not blending whereas with incomplete dominance you see both alleles effects but they've been blended.

Answer:
The correct answer is option a-"oceanic lowstand".
Explanation:
An oceanic lowstand is defined as a geological phenomenon at which the sea level is at a low point and the continents are mostly emergent. The Earth has been on onceanic lowstands historically. This has been identified by different evidence, including the Gulf Coast rivers formation of braided channels.
Answer: The oxygen content of the water decreases
Explanation:
The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, the oxygen content of the water decreases.
The temperature and the salt content of a body of water determines how much oxygen it can hold.
The oxygen content of warm water decreases because the temperature of the water causes the water molecules to move faster. This leads to the expulsion of oxygen from the water, making it contain less oxygen.
Also, salty water will lead to a decrease in oxygen because of the presence of sodium chloride ions.
Therefore, a warmer and saltier water will contain a less amount of oxygen.
