Answer:
The consumption of mosquitoes by bats and the control of flooding provided by tropical forests in mountainous areas of central america are examples of <u>ecosystem services</u>.
Explanation:
Ecosystem services can be described as the functions performed by parts of the ecosystem which benefit in regulating the ecosystem. These services offer a huge help to humans without the humans having to perform any work. For example, in the above question, humans are naturally getting rid of mosquitoes because the mosquitoes are being consumed by the bats. The floods in Central America are also being controlled by the tropical forests and humans have no work in it. Hence, both these examples show ecosystem services.
Answer:
Presence of specific antigen receptors on the surface of Immunocompetent B and T cells make them to generate immune response against specific antigens only.
Explanation:
The cellular and antibody-mediated immune responses are specific in nature. This means these immune responses are generated for particular foreign molecules or antigens only. These immune responses include B and T lymphocytes. Before T cells leave the thymus or B cells leave the red bone marrow, they develop immunocompetence. Immunocompetence is the ability to carry out adaptive immune responses. During this process. B cells and T cells make distinctive proteins and insert them into their plasma membranes. Some of these proteins function as antigen receptors capable of recognizing specific antigens. This is why the B and T cell-mediated third line of defense are specific in nature.
For example, antibody-mediated immune responses generate the memory cells for most previously encountered antigens to ensure the generation of more rapid and vigorous response during any further encounter with the same antigen.
