Answer:
The correct answers would be maintain chromosome number through generations and cause genetic variations by recombination.
In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.
It helps in the formation of gametes in sexually reproducing organisms.
These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.
In absence of meiosis, the chromosomal number would have doubled after each generation.
In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.
During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.
Answer:
Because you need energy.
Explanation:
When you eat carbs before any event that consists of running or any other activities, the carbs will fuel you up. Carbohydrates give you energy for a long period of time.
Answer:
<em><u>Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.</u></em>
Explanation:
Glycolysis is an oxidation reaction in which glucose reacts with oxygen molecules and oxidized. By oxidizing glucose, it produces pyruvate, adenosine triphosphate (ATP) and nicotinamide adenine dinucleotides (NADH). Glycolysis has two phases. In the first phase, 2 ATP molecules are invested for the phosphorylation of glucose to break down into a simpler one. In the second phase of glycolysis, 4 ATP molecules are earned back with 2 NADH and a simpler form of glucose (6C) to pyruvate (3C) by oxidizing glucose.
