Cytokinesis occurs after but events leading up to it actually begin during a. anaphase; telophase b. telophase; anaphase c. telophase; prophase d. anaphase; prophase

B. telophase; anaphase

Explanation:

Cytokinesis is a process through which the cytoplasm of the mother cell gets divided and distributed equally in the daughter cells. In animal cells, this process begins in anaphase and continues till the end of telophase.

Mitosis basically comprises 4 stages :

(1) Prophase

(2) Metaphase

(3) Anaphase

(4) Telophase

Till prophase and metaphase most of the events that occur are concerned with initial changes in the nucleus like condensation of chromatin and lining up of chromosomes in the equatorial plate. But, as the mitosis proceeds further the events related to separation of chromatids and their movement towards opposite poles also gets completed till anaphase. So, the only major event left after that is cytokinesis which begins in the anaphase itself and gets completed by the end of telophase.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.

it's a.true. i'm kind of smart.
