Answer:
A. In plants, a new cell wall forms to split the cell
Explanation:
In animal cells, they don't have a cell wall. During mitosis, they just split the cell membrane in order to create 2 new cells. In plant cells, they have cell walls. During mitosis, they create a new cell wall and place it in-between the 2 cells to create 2 new cells.
I think option B
Explanation:
Because earth tetonic plates
<h2>A) is the correct option </h2>
Explanation:
Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
- In the given example of rabbits, those that strictly eat grass will even survive after drought because plants will try to keep themselves green and there will be no production of berries and flowers hence these rabbits will shift their food source to green plants and will be favored
- But those rabbits those that strictly eat berries and flowers will not be able to survive because they were strictly dependent on berries and flowers for their food as a result they will be unfit and natural selection will be against those rabbits
Answer:
b. the activity of lipoprotein lipase.
Explanation:
Lipoprotein lipase (LPL) is considered or known to be a rate-limiting enzyme that hydrolyzes circulating triglyceride-rich lipoprotein such as very low density lipoproteins and chylomicrons.
It is known that the Lipoprotein lipase is activated by glucagon and adrenaline. And this why the activity of LPL increases in muscle tissue and decreases in adipose tissue, during fasting while , its activity decreases in muscles tissue and increases in adipose tissue.
It is known that, it plays an important role in breaking down fat in the form of triglycerides, which are carried from various organs to the blood by molecules called lipoproteins.
In conclusion, women fat cells in the breasts, hips, and thighs produce abundant LPL, storing fat in those body sites , while in men, fat cells in the abdomen produce abundant LPL.
