Answer:
B. Smaller fragments travel faster and farther than larger fragments.
Explanation: Shorter molecules move faster and migrate farther than longer ones because shorter molecules migrate more easily through the pores of the gel. This phenomenon is called sieving. [2] Proteins are separated by charge in agarose because the pores of the gel are too large to sieve proteins.

Based on the carrying capacity of the habitat and the changes that occurred in number of the two snake species, correct option is They occupy the same niche and are competing fully for all resources; option D
<h3>What is carrying capacity of a habitat?</h3>
The carrying capacity of a habitat is the maximum number of species the available resources in that habitat can sustain.
The data given of the species of snakes, Species A and Species B, indicate that they are both present in the habitat after a change occurs in the habitat.
Since the population of Species A became zero after Species B was introduced in the habitat, they occupy the same niche and are competing fully for all resources.
In conclusion, the competition between the species of snakes is responsible for the decline in Species A.
