Mountain chains match up where South America collided with Australia to form Pangaea.
Answer:
In sexual reproduction, two parents are required to produce a new organism. Most plants and animals, including human beings, reproduce sexually
2. the production of new organism by combining genetic information from two individuals of different types (sexes). in most higher organisms, one sex (male) produces a small motile gamete which travels to fuse with a larger stationary gamete produced by others (female).
<span>grass → rabbits → snakes → hawks. This chain supports the assumption that each population supports the next tropic level
because it tells about the next tropic level and flow of energy from one to the next
so correct option i conclude is A
hope it helps</span>
The purpose of MHC molecules is to bind and display pathogen-derived peptide fragments on the cell surface so that the relevant T lymphocytes can recognise them.
<h3>What are MHC proteins, or major histocompatibility complex proteins?</h3>
MHC, or the major histocompatibility complex, is a set of genes that produce proteins located on the cell surfaces and that aid the immune system in identifying foreign objects. In all higher vertebrates, MHC proteins are present. The complex in humans is also known as the HLA (human leukocyte antigen) system.
<h3>What exactly are MHC proteins, and why are they crucial?</h3>
The major histocompatibility complex (MHC) is a collection of genes that code for cell surface proteins that play a significant part in the immune response. MHC molecules have a major role in how they display antigens.
