Hi there!!
The answer is C.
The smoke from a cigarette can paralyze or even kill cilia!! Also, when smoking burns little holes in the lungs, the overabundant mucus gathers there. Bacteria and viruses get caught in these pools, causing the smoker to cough forcefully to attempt to remove the excess mucus.
Hope this helps!!
<span>This is an example of genetic engineering, also known as genetic modification. Many different techniques may be employed depending on the ultimate goal of the gene transfer, and genetic engineering can be carried out in both plant and animal species. Genetic engineering can be used for many purposes, such as improving disease resistance or crop yields, enhancing specific characteristics or developing new medicines.</span>
