Answer;

-Because the chemical groups that form hydrogen bonds are in the wrong positions.

Explanation;

-A base pair is any of the pairs of nucleotides connecting the complementary strands of a molecule of DNA or RNA and consisting of a purine linked to a pyrimidine by hydrogen bonds.

-The base pairs are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA or in hybrid DNA-RNA pairing. A mutation in the sequence of DNA that makes an adenine to be paired with a cytosine results to an unstable interaction because the chemical groups that form hydrogen bonds are in the wrong positions.

1. A caelifera, or more commonly known as the grasshopper belongs in the animal kingdom. Grasshoppers are a leafy green and can be found in a variety of habitats. They can be found in lowland tropical forests or grasslands. Higher classification for the grasshopper would be Orthoptera. Grasshoppers are jumping insects that belong to the arthropod phylum.

Strong, long hind legs that help them jump. This adaptation helps them get away from harm and jump higher.

3. I said some in the first paragraph.

4. Important in grassland ecosystems and play a role in the nutrient cycling.
