The answer to the question: Class II MHC proteins are found on which of the following cell types, would be: on macrophages and lymphocytes, particularly T-Cells.
Explanation:
MHC, or Major histocompatibility complex, is a very important part of the immune response that the body gives against an invading pathogen, or other foreign substances. There are three types in the human body, Class I, Class II and Class III and each of them will play a role on the cellular membrance of different types of cells and mediate different types of responses. In the human body, this histocompatibility complex is best known as HLA, or human leukocyte antigen, and it will ensure the recognition, or non-recognition of substances, tissues, and other organisms, by the human immune system. Class II, as mentioned before, are most usually found on the immune cells macrophages and lymphocytes, and they are the ones responsible for presenting antigens to these proteinic antibodies so that the immune cells can initiate a proper immune response.
The reason why humming birds need long beaks is to be able to get the nectar from the flowers, kind of like how we need straws to drink out of to go cups. Humming birds also have very long tongues that also help this process. Since humming birds beaks help them get the food they need, it makes them more successful in their environment.
