Answer: The primary hypothesis for extinction of mammoth was considered to be hunting by humans. A group of scientist thought that mammoth did not had genetic diversity until it was prooved as one large homogenous group. Hunting by humans were kept on the first place leaving the other factors like climatic change and disease behind. But the reality was something else, mammoth were divided into two groups, out of these two one group died before the appearance of the humans.

1. With respect to oxygen requirements, an <u>aerobe </u>can use gaseous oxygen and possesses enzymes to process toxic oxygen products.

<h3>What are enzymes?</h3>

Proteins called enzymes aid in accelerating our bodies' chemical reactions, or metabolism. Some compounds are created, while others are broken down. Enzymes are a component of all life. Enzymes are created by our bodies spontaneously.

2. Expanding on this classification, an <u>obligate </u>aerobe cannot grow without oxygen.

3. Still other organisms, called<u> facultative anaerobes</u>, metabolize by aerobic respiration but can adapt to anaerobic environments.

A facultative anaerobic organism is one that can switch from aerobic respiration to fermentation in the presence of oxygen to produce ATP.

Compare the shapes of the organisms that have cell walls with those that do not have cell walls.

inna [77]

The best answer is A. The purpose of the cell wall is to hold the cell in a specific shape, usually rectangular or square. For example, a plant cell's wall keeps it rigid so that the plant can stand up.

If the cell does not have a wall, it can easily change shape to accommodate for things coming in and out of the cell.

Hope this helps!
