Explanation:
The higher the altitudes, the lower the temperature.
At high altitudes, molecules tend to be more spread out, so the density of the molecules decrease.
Point mutations are the substitution of a single nucleotide, which creates a different codon and therefore a different amino acid. the incorporation of a different amino acid in the protein can completely disrupt the normal function of proteins.
Thanks to the presence of a nucleolus, cells can generate and interact with proteins that help them generate more cells and perform other complex tasks.
