I believe that the answer is (A) , cause if their hetero then it could be a 50/50 chance so if its not (A) then it might be (D)
forgive me if i am wrong, have a nice day! :)
Answer:
They look like X's (X shape)
Explanation:
The X shape are replicated chromosomes and are called the sister chromatids.
The answer is C. nitrogen.
Plants are main producers in ecosystems so, primary productivity of ecosystems depends on them. Carbon is necessary for plants, but it is widely present in plants. On the other hand, calcium and sodium are not as essential. However, nitrogen is important for plants because it is necessary to make proteins. Proteins take part in many different processes such as photosynthesis (this is actually primary productivity). But, nitrogen is not available to plants, they cannot absorb it simply from the air but rely on some symbiotic bacteria which are able to.
Answer:
36 chromosomes in each cell
Explanation:
Mitosis is an equational division which means that it does not reduce or change the number of chromosomes in the daughter cells. Mitosis in a single parent cell produces two daughter cells each having the same DNA content and the number of chromosomes is present in the parent cell. Each chromosome after the S phase has two sister chromatids that separate from each other and are segregated to the opposite poles of the cell during anaphase of mitosis. Therefore, a cell with 36 chromosomes will form two daughter cells after one round of mitosis. Each daughter cell would have 36 chromosomes.
