Why is mitosis important to unicellular organisms?

a. Mitosis is the way in which cells become larger in size.

b. Mitosis is the way in which two cells come together to form daughter cells.

c. Mitosis is the way in which different types of cells are created.

d. Mitosis is the way in which new cells are created.

D

Explanation:

you can't take one type of cell and create a brand new one. This gets rid of C

the only cell that increases in size is fat cells, this gets rid of A

Mitosis is for all cells, except sex cells. Daughter cells relate more to sex cells than other cells. Sex cells go through meiosis to create daughter cells. This also gets copies DNA. This gets rid of B

Basically: Mitosis is how we make new cells from the original cell (Think Zygote cell)

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
