<u>Answer</u>:
Disruptive selection tends to increase genetic variation
<u>Explanation</u>:
Otherwise called as the diversifying selection, which further tell us the changes taken place in genetics population in which the extreme values for the trait are favoured over intermediate values. The variance of the trait that are increased and also the population which will be divided into two different groups. It is a natural selection which selects against the average individual in the population. It happens when the individuals mate and who survive the best.

Answer:
Explanation:
- Organisms contain the same unstable elements as those found in rocks. - Elements in rocks decay at the same rate as elements in the remains of organisms. - Rocks and organisms both have gases trapped inside that are measured to determine. age.
Answer:
All prokaryotic cells have a nucleoid region, DNA and RNA as their genetic material, ribosomes that make proteins, and cytoplasm that contains a cytoskeleton, which organizes and supports the parts of the cell.
1. The Burmese python is an invasive species in the Everglades ecosystem. This means its numbers increase dramatically due to lack of natural predators. The python is feeding on small mammals such as rodents that feed of egg of animals such as the turtles. This, therefore, causes a ripple effect on the food web in the ecosystem e.g dramatically increasing turtle population.
2. Due to the lack of natural predators in the ecosystem, the Burmese python causes an imbalance in the Everglade ecosystem. They reduce the biodiversity of the ecosystem hence diminishing the quality of natural resources.
3. The number of Burmese pythons can be regulated by introducing a predator in the Everglade ecosystem. Examples of animals that can prey on the snake are eagles, pumas, lions, crocodiles, cobras, and humans. This will reduce the numbers of the Burmese python and restore the balance in the ecosystem.
