Nitrogen is fixed or combined, in nature as nitric oxide by lightning and ultraviolet rays, but more significant amounts of nitrogen are fixed as ammonia, nitrites, and nitrates by soil microorganisms.
The kind of molecule that is most likely to be injected into the mouse embryo is s known to be P4 injection as well as injection of estrogen.
<h3>How are they inserted into mice?</h3>
In the time after an ovariectomy is done to the mice, a continuous P4 injection (Progesterone Injection) is known to help keep the dormancy of the embryos for a lot of days.
There is also the act of Priming with the use of estrogen injection and this is often done at a high concentration ( that is about >10 ng/mouse).
Note that after this, a regular injection of estrogen is also done at a low concentration to be able to induce the transition process.
Hence, The kind of molecule that is most likely to be injected into the mouse embryo is s known to be P4 injection as well as injection of estrogen.

Answer:
The population of brown rabbit will be increasing because, they will thrive and reproduce, while that of white rabbits will be reducing because they will be dying.
Explanation:
The brown rabbits are easier to spot by the predators during the winter season,while the white rabbits are able to spot during non-winter seasons.
Therefore, when the warmer temperature last longer into the fall and the average temperature in the winter is getting warmer, there will be less snowfall in the winter, there is a an assumption or probability that the brown rabbits are less prone to predation, while the white rabbits are prone to predation.
In this sense,the population of the brown rabbit will be higher than the population of the white rabbits.
