There are many more examples of chemical digestion which takes place in the body. Chemical digestion is the breaking of larger more complex molecules into smaller, simpler ones that can be taken up by the cells more easily and readily by the use of chemical agents.. Chemical digestion is carried out primarily using biological molecules called enzymes. For example, the breakdown of starch is done by an enzyme known as amylase, which is present in the saliva.
Artificial selection is the type of selective breeding.
Selective breeding is process of breeding parents with distinct characteristics to produce offspring with more desirable characteristics.
Most of the time the breed of dogs were formerly selected for particular purposes, such as hunting or guarding which needs strong physical endurance. Hence, Selective breeding is evolved by human selection. For example racehorses, having particular traits are desirable in different breeds of dogs that compete in dog shows. Artificial selection, is selective breeding that is imposed by an selective process, in order to get the phenotype of desirable features.

Answer: The element with the greatest influence on cholesterol levels is the fat content of food. Not only the amount of cholesterol, but also the type of fat.
Explanation:
Cholesterol is a type of fat found in the body, which is used to make hormones and vitamin D. The liver makes cholesterol to handle these tasks, but cholesterol can also be incorporated into the body through foods such as meat, dairy, and poultry. If you consume a lot of these, the cholesterol levels could become too high.
There are two types of cholesterol:
- High-density lipoprotein (HDL) or “good cholesterol”. It transports the excess of cholesterol to be expelled so<u> it wont end up in the arteries. </u>
- Low-density lipoprotein (LDL) or “bad cholesterol”.<u> It transports cholesterol to the arteries, where it may collect in artery walls.</u> This could lead to a buildup of plaque known as atherosclerosis which can increase the risk of blood clots and if one of them breaks away and blocks an artery, it could cause a stroke or heart attack.
If there is a predominance of saturated fatty acids in the fat of the diet, a rise in serum cholesterol and LDL-cholesterol is caused. To lower the bad cholesterol, you should limit foods such as milk fats, fatty meats or sausage and include more fibre in your diet. On the other hand, <u>polyunsaturated fatty acids - for example, those present in seed oils or fish - produce their reduction. Monounsaturated fatty acids, such as those provided by olive oil, act like polyunsaturated ones and, in addition, tend to raise HDL-cholesterol, so their use entails a greater benefit.</u>
Answer:
The contractile ring shrinks through the center of the cell, evenly dividing the cytoplasm between the two halves. This indicates that cytokinesis is completed and the cell has been replicated.
