Answer:

The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species  is called self pollination.

Generally, the transfer of pollen grains by wind,animals,and water  to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.

Therefore during self pollination, the same genes are distributed  from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain  a particular plant would always breed true.

Additionally it prevent  the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.

The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get  weak and prone to diseases and infection. Because of poor resistant from lack of variation.

yKpoI14uk [10]

This argument would not be valid because it fails to take into account the <u>mechanisms </u><u>through which </u><u>evolution </u><u>occurs</u> and misunderstands the <u>second law </u><u>of </u><u>thermodynamics</u><u>.</u>

The second law of thermodynamics states that the total entropy of a system must always increase. The argument stating that this law disproves evolution given that evolution can be considered as a <u>decrease in entropy</u>, fails to realize that the <em><u>second law</u></em> states that the <u>total entropy </u>must increase, this does not mean that entropy cannot decrease at one point, to then increase more so at another.

The other aspect of evolution that this argument fails to account for is that evolution is a chaotic process. Evolution, though having a final product that may be considered as increasing in organization, is at heart <u>a </u><u>chaotic process </u><u>caused by</u><u> random mutations</u><u> and the fragile process of </u><u>natural selection</u><u>.</u> Therefore, rather than disprove it, the<em><u> second law of thermodynamics</u></em> is actually the driving force behind continued evolution.

Answer: colostomy

Explanation:

Colostomy is a surgical procedure which is used to remove waste or feces from the body when the body is incapable of expelling out the waste. A stoma is the opening either created surgically or naturally present. It is the opening in the large intestine it allows the removal of the feces out of the body. The feces is drain through the rectum into the pouch of the collection device.
