Fragile x syndrome is a sex-linked disorder found mostly in boys, characterized by mental impairment, large ears, a long face, heart defects, and flat feet. it is caused by a mutation to the gene shown in the picture above. the codon cgg is abnormally repeated many times, causing the cell to inactivate the gene. such a mutation is known as a(n) a) insertion. b) inversion. c) deletion. d) duplication.

Correct D). Duplication

It is a disease that is caused by the repetition of codon for many times, which will lead to inactivation of gene that is required for the proper function of brain and other body functions. It is a sex linked genetic disorder, which is caused to to lengthening or expansion of genes.

In these disease the codon triplet CGG is repeated several times, which causes mutation in the gene CFR1. The main symptoms of this disease is mental impairment and heart problem etc.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
