D i believe is the correct answer if i remember from my biology class
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.
Answer:
The given blank can be filled with thymus.
Explanation:
The secondary branch of immunological tolerance known as the peripheral tolerance occurs in the immune periphery, that is, post the maturation and exit of the B and the T cells from the primary lymphoid organs like thymus. The main objective of the mechanism is to make sure that the self-destructive B and T cells that managed to pass through central tolerance do not result in autoimmune disease.
This is false, DNA can duplicate it self
