Answer:
If I were to choose a plant or animal which is interesting, I'd choose the "cactus."
Explanation:
A "cactus" is truly a splendid plant owing to its <em>ability to survive in the desert </em>or<em> periods of drought.</em> Growing them is also not that challenging or difficult. However, this plant is prone to certain threats that may lead to its extinction.
- One of these threats is the <em>"over-collection of cacti." </em>Due to its versatile use, the cactus is often sold as an ornamental plant.
- Another threat is the number of pests, such as <u>snails</u> and<u> slugs</u>, that attacks it yearly. It is a delicious food for<em> mealy bugs, red spider mites, gnats, flies, etc.</em>
- People often misunderstand the <u>cactus' water level need</u>s. Some people over-water the plant and this often results to the bacteria, virus and fungi being attracted to it.

Answer:B.) Substitution
Explanation: Mutations are permanent changes in the nucleotide sequence of a DNA molecule. Substitution leads to a point mutation if only one nucleotide is replaced by another.
A substitution mutation occurs when one or more nucleotides in a DNA sequence is replaced by another nucleotide.
Example of substitution is in sickle cell hemoglobin in which valine replaces glutamate at position six in the two beta chains of hemoglobin. In a normal hemoglobin, the two beta chains of hemoglobin have glutamate at the sixth position but in a sickle cell hemoglobin, valine is found at position six on the two beta chains. This is also an example of a point mutation.
