Answer:
Myrmecophytes, otherwise known as ant-plants, share a mutualistic relationship with a colony of ants. This is when two organisms of different species each benefit from the activity of the other. There are over 100 different genera of myrmecophytes that can be found across the world's tropical regions
Explanation:
Answer:
CD4 on the surface of helper T-cells.
Explanation:
MHC class II ( major histocompatibility complex) molecules are processed from the exogenous source. The presentation of antigen on cells are important for the adaptive immune response.
MHC class II interact with CD 4 present on the surface of T helper cells. This interaction is important for the generation of an immune response. Helper T cells can release cytokines and can perform phagocytosis.
Thus, the correct answer is option (C).
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products. In a chemical reaction, only the atoms present in the reactants can end up in the products.
Hopefully this helps!
The primary difficulty is the fact that we do not know all of the organisms that currently exist in the world along with those that existed in the past.
