Answer:
Biologists can grow specific plants to detoxify an area contaminated with heavy-metal pollution using the method of <u><em> Bioremediation. </em></u>
To rid an area of mosquitoes, biologists introduced a species of fish into bodies of water that feed on the mosquito larvae. This method is an example of <em>Biological Augmentation.</em>
Explanation:
Bioremediation can be described as a process which uses plants or microorganisms to detoxify contaminants that are present in an area. The enzymes of a plant or animal tend to break down the contaminants and hence, we can make an area rid of contaminants in this way.
Biological augmentation can be described as a method by which organisms such as bacteria are introduced in an area to get rid of wastes.
Since color blindness is a sex-linked recessive genetic disorder, it is carried by a X chromosome. Males (XY) are affected if they get the affected X from their mother, since males only have one X, and it is therefore always expressed. Females (XX), however, get one X from their mother and the other from their father. So both parents have to pass a color blind X to be affected (both alleles, by the definition of recessive).
Even though the mother is not affected, she's carrying it because her father was color blind. And the father is not affected. However, in Turner's Syndrome, one X is destroyed after fertilization, so the other X is the daughter's primary (only remaining) X. Note: Turners only affects females. Therefore, this is a rare situation in which a daughter gets affected by an X-linked recessive condition.
