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.
The answer is <u>B: a mutation inhibiting human immunodeficiency virus from entering the host cell</u>
Answer:
Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible. For example, it has been estimated that an amount of water equivalent to roughly 100 times the volume of the cell diffuses across the red blood cell membrane every second; the cell doesn't lose or gain water because equal amounts go in and out. There are, however, many cases in which net flow of water occurs across cell membranes and sheets of cells. An example of great importance to you is the secretion of and absorption of water in your small intestine. In such situations, water still moves across membranes by simple diffusion, but the process is important enough to warrant a distinct name - osmosis.
Answer: Vacuole
Explanation:
Vacuole is a cell organelle that is lined with membrane and filled with cell sap that serves as a storehouse for many substances especially water. Hence, the cell membrane helps to remove excess water in cells
The correct answer is - A. Death rate.
We get the fertility rate from the birth rate and the death rate. More specifically, from the number of the children that are born in a given time frame (usually a year) we minus the number of the people that have died in the same time frame, so the difference between them gives us the fertility rate.
The fertility rate can be positive (in the difference is a positive number) and negative (if the difference is negative number).
