When during the cell cycle do chromosomes first become visible?

a.) during interphase
b.) during cytokinesis
c.) during prophase
d.) during the g1 phase

Answer;

C.) during prophase

Explanation;

-Prophase is the first phase of mitosis, the process of cell division in which a parent cell divides into two daughter cells that are similar to the parent cell, and is separated into four stages.

-During this phase of mitosis each chromosome becomes condensed and more visible, and there is the breakdown of the nuclear membrane and appearance of spindle fibers.

-Initially, prior to prophase, the chromosomes were long strands of DNA material called 'chromatin', which then curls up into tightly wound shapes called chromosomes.

the answer to you question is   jet streams

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
