Answer #1

Solution).NK (Natural Killer)cells would be most effective at fighting this pathogen because like cytotoxic T-cells, NK cells also play a role in destroying cells infected with intracellular pathogens.But unlike cytotoxic T-cells, NK cells kill targets in antigen non-specific manner. Therefore, NK cells can destroy this new pathogenic bacterium has been discovered -- an intracellular parasite that can prevent MHC molecules from being properly made in infected cells.

    Adaptive Immunity: Second Line of Defense—Cellular Defenses The T-cell receptors and CD4 and CD8 molecules interact with major histocompatibility complex (MHC) proteins. MHC proteins are found on most cells of the body. There are two variations, or classes, of MHC proteins. MHC class I is expressed on the surface of most cells of the body such as skin cells, liver cells, and others. Should a cell become infected with a virus, viral antigens are processed in the cells and expressed...

Answer: Beta cells (β cells) are a type of cell found in pancreatic islets that synthesize and secrete insulin and amylin. Beta cells make up 50–70% of the cells in human islets. In patients with type I or type II diabetes, beta-cell mass and function are diminished, leading to insufficient insulin secretion and hyperglycemia. The pancreas is...

In that population a mutation results in a parasite resistant genotype that spreads through the population through natural selection. A subsequent mutation in the parasite results in a genotype that is unaffected by the newly evolved resistant guppy genotype. What is the name of the hypothesis that explains this host parasite “arms race”.? 1b) What is this name...
