Q #1: Which of the following chemicals is released by one type of immune cell to directly activate another type of immune cell?

A. Lysozymes

B. Perforin

C. Cytokines

D. Granzymes

Answer Explanation

Cytokines are small proteins that act as chemical messengers between different types of immune cells. They can stimulate or inhibit the activation, proliferation, differentiation, and migration of immune cells. For example, interleukins are a type of cytokine that is produced by one type of white blood cell and can affect the behavior of another type of white blood cell. Lysozymes, perforin, and granzymes are all molecules that are involved in killing pathogens or infected cells, but they do not directly activate other immune cells.
Q #2: Which of the following reasons explains why it is important for new scientific findings to be published?

B. This prevents other scientists from performing similar tests.

C. Scientists will get paid if their findings are published.

D. Other scientists can validate or disprove the findings.

Answer Explanation

One of the essential aspects of scientific inquiry is the communication of results to peers and the public. Publishing new scientific findings allows other scientists to review, replicate, or challenge the methods and conclusions of a study. This way, science can advance by building on previous knowledge and correcting any errors or inconsistencies.
