The correct answer is option D, that is since genetic drift is random, it does not always favor the better or healthier organisms.
A mechanism of evolution in which the frequencies of alleles of a population change with generations because of sampling error is known as genetic drift. It takes place in all the populations of non-infinite size, however, its influences are strongest in small populations.
The green house effect refers to gases trapping the heat energy reflected from earth’s surface.
gases trapping heat energy reflected from the earth's surface.
<u>Explanation:</u>
It is the greenhouse effect that made earth a planet that supports life. if there was no green house effect the earth would have been too cold to live on. Sunlight contains rays like UV and infrared.
UV rays being harmful are blocked by the ozone layer in the stratosphere. Infrared rays that enter the earth’s atmosphere are trapped by the greenhouse gases like carbon dioxide, water vapour, methane etc. the trapped infrared rays help in providing warmth.
