Which of the following cell types of the innate immune system does not perform phagocytosis? And Why?
Neutrophils, Basophils, Macrophages, Eosinophils
Answer:
Macrophage
Explanation:
Monocytes move from the systemic circulatory system into general connective tissues, where they differentiate into what phagocytic cell type?
I think...
Basophils are cells of the innate immune system that does not perform phagocytosis. These cells (basophils) release granules of enzymes to fight against harmful microorganisms and recruit other inflammatory cells.
When harmful microorganisms (e.g., bacteria) or potentially harmful particles enter the body, different cells of the immune system respond by trying to isolate and destroy them.
Phagocytosis refers to the biological by which phagocytic cells ingest/engulf other cells (e.g., bacteria) or harmful particles.
Phagocytic cells of the immune system include neutrophils, macrophages, and dendritic cells.
Basophils are white blood cells that are responsible for releasing granules of enzymes to fight against harmful microorganisms (e.g. bacteria) and recruit other inflammatory cells (e.g., macrophages, eosinophils) to the site of infection.

What is base pairing? (and Chargaff's rule)?
Answer:
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G).
Explanation:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

The children in a middle school classroom are all exposed to chicken pox one week. Among these students are John, who had chicken pox when he was much younger, and Sara, who has never had chicken pox. Which student do you expect would be less likely to become ill with chicken pox following this exposure and why? (5 points) John: he has naturally acquired active immunity to chicken pox from his previous exposure. Sara: she has naturally acquired passive immunity to chicken pox from exposure to other students. John: the pathogens that cause chicken pox will no longer be able to enter his body. Sara: since she has not suffered from chicken pox, her immune system is probably stronger than Johns.
Answer:
John: he has naturally acquired active immunity to chicken pox from previous exposure.
Explanation:
Your body naturally has some immunity to things that aren't you, but when you get sick with a specific pathogen, your body begins to make antibodies that specifically recognize that pathogen. Each antibody only recognizes one pathogen, and it floats around waiting to find it again so it can tell your body to kill it before you get sick again. This is why we become immune to chicken pox; after the first time you beat it, your body has the labeled antibodies and it can quickly destroy the pathogen before you get sick again.
Answer:
John: he has naturally acquired active immunity to chicken pox from his previous exposure.
