Genetic engineering is due to the human selection of desired phenotypes, whereas natural selection is a slow process of differential survival and reproduction.
<h3>What does natural selection mean?</h3>
According to the evolution theory, natural selection is a slow process of differential survival of the fittest organisms in a given environment.
Conversely, genetic engineering refers to the molecular biology techniques used in the laboratory to produce organisms expressing desired phenotypes.
In conclusion, genetic engineering is based on human molecular biology techniques, whereas natural selection refers to differential survival and reproduction in nature.

there are two distinctions of genders in humans, one is biological and the other is socially constructed.
biologically, man and women are distinguish by the gonads, such are men posses Penis and and women have Vaginas. secondly, through penis men produces sperm which is necessary for fertilization, while women have ovum which is serves as the carrier of sperm and produces a new young ones after , sperm meets egg.
socially men and women are constructed as men are to face the social world while women have to care for the family and house.
Vesicular breathing sounds are result from or are produced because of a person's need of breathing. In order for a person to breathe, gas exchange is needed to have an oxygen to breathe and to regulate the blood flow. To do this, the lungs is needed and with the help of their components namely the aveolar sacs, which enables to fill the air in the lungs, resulting to or producing vesicular breathing.
Materials that cannot be broken down by biological processes are known as non- biodegradable materials.
Such materials cannot be changed to a harmless natural state by action of bacteria. in other words, non biodegradable materials do not decay and are considered harmful to the environment.
Examples of non biodegradable materials include plastic products, electronic , construction waste. Common non biodegradable waste materials include plastic water bottles, tin cans, tires and computers. Such materials are discarded into landfills in an indiscriminate way, posing a major risk to the environment.
