A response to a change in the environment.
2 of 11
Answer:
C Adapted to their environment
Explanation:
Regular bears don't have as thick of a coat as polar bears do because they haven't been in the cold habitat that polar bears have
Answer:
C. Adapted to their environment
Explanation:
Look at all of the different types of bears. Each had to adapt to survive in their given environment. Polar bears adapted to take on the cold which is why they have thick fur coats and also white fur to blend in to their environment.

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.

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.
