( Am not completly sure, but i think this is the answer)
Answer:
Hail.
Precipitation is also known as rainfall and it is important as a way of balancing and regulating the earths atmospheric conditions. Precipitation could involve rainfall, snow or hail.
Hail is usually accompanied by a storm which produces precipitation in the form of ice particles. This happens when the dew point is below freezing which results in the formation of ice crystals.
Answer:
i believe the answer would be genetics since you are altering the DNA of the plants
Answer:
A person can have normal chromosomes in number and structure, but still have a disease or condition caused by a mutation in one or more of the genes on the chromosomes. A single gene defect usually does not cause the chromosome structure or number to be abnormal.
Explanation:
I'm not sure if this is correct but hope it helps.
Natural selection is nature’s way of keeping the best fit-to-live things alive, and so on continue to the next generations.
For example, if a rabbit has a limp, it is bound to be out run and eaten by a predator relatively early in its life (unless it is extremely lucky.) Because of this, it is unable to reproduce, and there genes that it contained to have its limp are unable to spread through inheritance. Natural selection goes both ways. For example, if a hawk has very god vision, it will be able to scope out its prey easily, so it will thrive. Therefore, when it produces offspring of its own, its trait of good eyesight will pass on to its offspring.
So, as enough time goes on, the bad traits will be weeded out and the good ones will remain.
