Answer: Point mutation is easily reversible, thus non-lethal
Explanation:
Point mutation is caused by exchange of a single nucleotide for another. These change is called
1) Transition (when a purine base substitute another purine base, or pyrimidine bases substitute each other)
2) Transversion (when a purine base substitute a pyrimidine base).
However, note that a point mutation can be easily reversed by another point mutation; so, the claim that a nucleotide difference in the Hsr12 gene caused the human disease is inaccurate
Unfortunately this question is incomplete as no options are provided. IN actual fact,<span> four muscles are involved in mastication. Three of these are responsible for biting down, namely the masseter, the temporalis and the medial pterygoid, whereas one, the lateral pterygoid, is responsible for opening of the jaw</span><span>. All four muscles help to move the jaw laterally.</span>
The answer is <span>B. The type of fertilizer.</span>
<span>An independent variable is variable that is not affected in the
experiment. It is what experimenter controls. On the other side, a dependent
variable is called dependent because it depends on the independent variables.
It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of
fertilizer. So, the growth of pea plants is the dependent variable and different
type of fertilizer is the independent variable.</span>
Answer:
I have know idea sorry
Explanation:
um yeah ask like someone else lol
When a meteoroid passes through earth's atmosphere, it heats up due to air resistance. The heat causes gases around the meteoroid to glow. most meteoroids that enter earths atmosphere disintegrate before they hit the ground.
