Answer:

gametes are reproductive cells such as sperm and eggs. as gametes are produced the number of chromosomes must be reduced by half.

Explanation: why? the zygote must contain genetic information from mother and from father cells so the gametes must contain half of the chromosomes found in normal body cells.

In the interview with CHLOE ESTEROL, O2 says that if glucose can't enter The Cell, then cellular respiration would be affected.
mrs_skeptik [129]

Answer:

I and V

Explanation:

All living organisms undergo the process of CELLULAR RESPIRATION, which is the metabolic process of breaking down glucose in order to release the stored energy in its bonds and convert them in usable form by the cell (ATP). Cellular respiration can be aerobic (presence of oxygen) or anaerobic (without oxygen). This process involves Glycolysis which is an initial step undergone by all organisms because it does not require oxygen. Glycolysis occurs in the cytoplasm of living cells in both prokaryotes and eukaryotes.

Aerobic cellular respiration further contains Kreb cycle and Oxidative phosphorylation which occurs in the mitochondria of eukaryotic cells. In a nutshell, glucose is broken down to produce ATP which the organism uses to power its life processes. water and Carbondioxide (CO2) are also released as byproducts.

The General equation for aerobic cellular respiration is as follows:

C6H12O6 + 6O2----> 6CO2 + 6H2O + ATP

A mother's body undergoes many changes to accommodate the developing fetus during pregnancy. Most doctors blame this discomfort
hoa [83]

Answer:

1. Integumentary System

2. Digestive System and Endocrine System

Explanation:

An organ system combines multiple organs to perform one or more biological functions.

The integumentary system which human skin, is an organ system that protects the outer body. So the stretch marks women experience during pregnancy are evident on the skin, and since it was mentioned in the question that "A mother's body undergoes many changes to accommodate the developing fetus during pregnancy" it can be concluded that the skin stretched due to fetus development.

The digestive system here, the liver, can get disordered by a liver disease known as Cholestasis, which alters the flow of bile produced by the liver for digestion and can lead to bilirubin buildup poisoning blood and causing itchiness that can be experienced during pregnancy.

The Endocrine system is the Hormone center of the body, it affects the mood, and can cause itchiness too.
