Answer:

The answer is A. Each couple has only two children

Explanation:

The replacement reproductionis inferred to the minimum reproduction that a closed population needs so that it remains endlessly in time without decreasing its volume. This value is around 2.1 children on average. This is understood that a woman must reproduce herself and her partner, the decimal is because there are women who have no children.

HELP PLEASE Sucrase, lactase, and maltase break down disaccharides into monosaccharides. Monosaccharides are transported to the
nalin [4]

Explanation:

In the given question, the digestion of monosaccharides has been discussed and the steps of digestion in the digestive system are:

1. The digestion of carbohydrates begins in the mouth where amylase breaks down the starch.

2. The sugars are not completely digested in the mouth therefore they travel from mouth to the stomach.

3. In the stomach, there are no enzymes to digest the sugars.

4. Then, food enters the intestine where intestinal secretions breakdown the sugars.

5. The intestinal juice breaks down the oligosaccharides into diassacharides and these disaccharides are further broken down by maltase, sucrase and lactase.

6. After this, the monosaccharides are formed and these are easily absorbed into the bloodstream.

7. Pancreatic amylase breaks down starch into monosaccharides.

This completes the digestion of the carbohydrates.

How does a plant obtain carbon dioxide for photosynthesis
icang [17]

Answer:

Plants get carbon dioxide from the air through their leaves. The carbon dioxide diffuses through small holes in the underside of the leaf called the stomata.  The lower part of the leaf has loose-fitting cells, to allow carbon dioxide to reach the other cells in the leaf.

Removal of phloem tissue leads to gradual death of the plant. Why does this happen?
pogonyaev
The phloem is essential for transporting sugars the plant has made to other areas of the plant, this is necessary as some areas of the plant cannot perform photosynthesis or perform it at a much slower rate. E.g. the roots can't perform photosynthesis to get the sugars it needs because they aren't exposed to light, but they still need energy to function and without sugar transport by the phloem they would not get this so areas of the plant would die
