Answer:
-Prophase.
Explanation:
Cell cycle involves a series of events that leads to formation of two daughter cells by division of a parent cell. It can be divided into two phases, interphase and mitotic phase (M phase)
The M phase involves division of nucleus and cytoplasm to produce two daughter cells. It is divided into prophase, metaphase, anaphase, telophase and cytokinesis.
Hence, the first stage of M phase is prophase, in which condensation of chromosomes begins, nuclear membrane disintegrates, and nucleolus starts to disappear.
Thus, the correct word to be fill in the blank is 'prophase
B. By increasing the activation energy of the reaction
C. By decreasing the activation energy of the reaction
D. By increasing the energy of the products of the reaction
E. By decreasing the energy of the products of the reaction
Answer:
Enzymes help to carry out biochemical reactions C). By decreasing the activation energy of the reaction
Explanation:
Enzyme catalysis An enzyme catalyzes a biochemical reaction by binding a substrate at the active site. After the reaction has proceeded, the products are released and the enzyme can catalyze further reactions.
cell membrane
B.
nucleus
C.
chloroplast
D.
chromosome
Answer:
Explanation:
The prokaryotic cell or prokaryotes are single celled organisms that do not posses organelles or membrane bound structures hence they do not have a nucleus but they posses single chromosome which is a piece of circular double-standard DNA in the nucleoid.
where plants, animals, landscape and climate all interact.
where plants, animals, landscape and climate are all independent of each other.
where organisms are independent of each other.
Answer:
Multiply dna
Explanation:
So they can be genetically identical
