Adenine, Guanine, Cytosine, Thymine?
The right answer is C. (non sens mutation are the most harmful)
In genetics, a nonsense mutation is a point mutation in which a nucleotide of a codon is changed, inducing the replacement of a codon encoding an amino acid (UGU, cystein) by a stop codon (UGA). The resulting protein, truncated and therefore incomplete (because the translation ends prematurely, and therefore we will have a truncated protein), is generally non-functional.
A type of speciation that leads to rapid extinction
In general, plant sources of protein provide less absorbable forms of iron, zinc, and calcium as compared to animal protein sources.

2. Digestion, absorption, and elimination
6. Physical is when the food is physically broken down. (Chewing of the mouth) chemical is with the help of substances
