The cell cycle is the period of time from the beginning of one cell division to the beginning of the next.

The cell cycle is the series of biological events which cells go through as they grow and divide. The cell cycle has two phases.

(i)                  Mitosis

(ii)                Interphase.

Interphase is broken down to G1 which is growth phase, S which is Dna synthesis phase and G2 which is growth phase again. In Mitosis it consists of anaphase, telophase, prophase, and metaphase.

The cell cycle begins in cytokinesis and ends in Mitosis. Mitosis cannot start before interphase ends because mitosis requires a lot of energy and nutrients to go through the process.Since interphase is the beginning of G1,Dna synthesis and G2 comes to play, it helps to create nutrients and energy.

Let’s have an example of a menstrual cycle. You bleed at the beginning of a cycle not at the end. The first day of your period is the menstrual cycle.

Cell respiration begins with
irinina [24]

Answer:

Cell respiration begins with Glycolysis .

Explanation:

Glycolysis  is the first and initial step in the cellular respiration. Cellular respiration is the anaerobic process, which takes place in cytosol of the cells. Two molecule of pyruvate(CH3COCOO-) are formed from 1 molecule  of  glucose(C6H12O6)through glycolysis. The  NADH and  ATP are high energy molecules formed when the free energy are released. It is the process which takes place through a series of ten enzyme catalysed reactions. 10 enzymes are required to break down the sugar molecule. It occurs in cytoplasm.

Bingel [31]

The correct answer is:  d) begins later in life

Eggs or female reproductive cells are formed well before birth in a huge number (primordial oocytes). But, the number of oocyte decreases after birth constantly (there are 2 million oocytes at birth and 40,000 of them in puberty). At menopause, no egg cells are left.

On the other hand, the first sperms are formed only from puberty, but the production of those cells never stops.
