<h2>Peptidoglycan Cell Wall </h2>

Explanation:

A cell wall containing peptidoglycan and distinctive ribosomes
Bacterial cell dividers are made of peptidoglycan (additionally called murein), which is produced using polysaccharide chains cross-connected by irregular peptides containing D-amino acids
Gram-positive microscopic organisms have a thick cell divider containing numerous layers of peptidoglycan and teichoic acids
Ribosomes are small particles which is related proteins that capacity to synthesize proteins and comprising of RNA
Proteins are needed for many cellular capacities, for example, directing chemical procedures and repairing damage
Ribosomes can be discovered drifting inside the appended to the endoplasmic reticulum or cytoplasm

What was the first step of aerobic cellular respiration to evolve? What evidence is there to support this ?

kozerog [31]

The first step of aerobic cellular respiration to evolve is glycolysis, the evidence that there is to support this is with through the cytosol of the cytoplasm in which this stage takes place as this is the process where glucose has been split in two molecules by the enzymes.

Olympic athletes train in Colorado Springs, Colorado because this location is at high altitude and near the 14,000 foot Pikes Pe

Stels [109]

Answer:

A: Oxygen levels are low and, therefore, more red blood cells are produced, giving the athletes an advantage when competing at lower altitudes.

Explanation:

At high altitudes, the partial pressure of oxygen is lower compared to lower altitudes. The body system try to adjust to lower oxygen level by undergoing several physiological changes. Depending on the duration spent in high altitude, the body can either try to adjust in the short term or acclimatize for a longer term.

One of the processes the body undergoes during acclimatization is an increase in red blood cell production. The kidney secretes erythropotein in response to inadequate oxygen in body tissues, and this makes the liver to increase erythrocyte production.

The increase in red blood cell production correspondingly increases the oxygen-carrying capacity of the blood as a result of increased hemoglobin. This condition persists for a few weeks even after the body returns to lower altitude where oxygen is adequate. Increased oxygen capacity means the rate of energy production (through respiration) within the body will also increase

Hence, those who acclimatize to high altitude usually experience increased capillary density, tissue perfusion and improved athletic performance at lower altitudes.

The correct option is A.

When gametes combine to form a zygote, the chromosomes number of the zygote is now referred to as

pychu [463]

Answer:

When gametes combine to form a zygote, the chromosomes number of the zygote is now referred to as diploid.

Explanation:

The term diploid refers to the complete chromosome charge of a cell, in this case a somatic cell. Sex cells, or gametes, contain only half of the chromosome charge that each parent confers on their offspring, and are called haploid cells.

Two gametes, haploids, each contribute their half of the chromosome charge to form a diploid cell, the zygote.
