Answer:
B. II only. Brain damage resulting from the bioaccumulation of heavy metals.
Explanation:
The mercury concentrated mine tailings dumped in the nearby water bodies undergo methylation process and is converted to methyl mercury by bacteria in the aquatic environment. The aquatic plants absorb this and when fishes eat these plants, they also get contaminated with mercury. This leads to bioaccumulation of mercury in the aquatic environment.
Mercury is a neurotoxin and contamination in humans by consuming mercury-contaminated fishes leads to neurological damage like memory impairment, decreased concentration and IQ, decreased motor skills or dexterity, tremors, movement disorders, depression, anxiety, or psychosis. Chronic mercury contamination can lead to neurological disorders like Alzheimer’s, autism, Parkinson’s etc.

Aneuploidy is a defect on the number of chromosomes a cell has. Human cells have 46 chromosomes, an additional chromosome (47) or a missing one (45) is an aneuploidy.

Answer:
A, These proteins are created in the body by condensation of amino acids under the influence of enzyme catalysts, using patterns or direction from the nucleic acids in the cells. The amino acid units in a protein molecule are held together by peptide bonds, and form chains called polypeptide chains.
