Answer:
Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations
Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
A subset of MHC molecules known as Class II of the Major Histocompatibility Complex (MHC) is often only found on specific antigen-presenting cells such as dendritic cells, mononuclear phagocytes, specific endothelium cells, thymic epithelial cells, and B cells.
<h3>Do macrophages contain MHC 2?</h3>
In order to deliver Listeria monocytogenes to T cells for phagocytic processing, class II MHC molecules are found in macrophage lysosomes and phagolysosomes.
<h3>Are macrophages MHC-positive?</h3>
Exogenous antigens can be processed by macrophages and displayed on MHC molecules.
<h3>Which cells possess MHC 1 vs. 2?</h3>
All nucleated cells contain MHC I glycoproteins. Specialized antigen-presenting cells are the only ones to contain lls.

<span>Some of the things that would make the experiment invalid would be, if there was a variation in the behavior of the class with respect to food - for example, if some people ate their breakfast earlier than the others. This then would mean that some students would have already digested their breakfast during the morning classes and the others would still be digesting. </span>
C. nucleic acids (consisting of genes which encode for specific proteins to be synthetized)
Answer:
C. Mitosis
Explanation:
Mitosis is a type of cell division in which a single parent cell is divided into two identical daughter cells. In mitosis, the parent cell is diploid i. e. double number of chromosomes. When replication of chromosome occurs, two identical copies of chromosome are made which is distributed to each daughter cell so the daughter cells are also diploid.
This type of cell division occurs in somatic cells or body cells which helps in the growth and repairing of the body.
