1. The cell-mediated immune response is associated with B-cells.

Explanation

The cell-mediated immune response is not associated with B-cells. B-cells are responsible for the humoral immune response, which involves the production of antibodies. The cell-mediated immune response, on the other hand, is primarily carried out by T-cells, which directly attack infected cells. Therefore, the correct answer is False.

2. Class 1 MHC molecules are to cytotoxic T-cells as Class 2 MHC molecules are to ______.

Explanation

Class 1 MHC molecules are responsible for presenting antigens to cytotoxic T-cells, which are involved in cell-mediated immune responses and target infected or abnormal cells for destruction. Similarly, Class 2 MHC molecules are responsible for presenting antigens to helper T-cells. Helper T-cells play a crucial role in coordinating and regulating the immune response by activating other immune cells, such as B cells and cytotoxic T-cells. Therefore, the correct answer is helper T cells or helper T-cells.

3. What is the main idea in the antibody-antigen relationship?

Explanation

The main idea in the antibody-antigen relationship is that antibodies sacrifice themselves to protect the body from antigens. This means that antibodies bind to antigens and neutralize them, but in the process, the antibodies themselves are destroyed. This self-sacrifice is crucial for the immune system to eliminate harmful antigens and maintain overall health.

4. How many types of T-cells are there?

Explanation

There are four types of T-cells. T-cells are a type of white blood cell that play a crucial role in the immune response. The four types of T-cells are helper T-cells, cytotoxic T-cells, memory T-cells, and regulatory T-cells. Helper T-cells assist other immune cells in recognizing and attacking pathogens. Cytotoxic T-cells directly kill infected cells. Memory T-cells "remember" previous infections to mount a faster response in case of reinfection. Regulatory T-cells help to suppress the immune response and prevent excessive inflammation.

5. Which of the following are barriers in the innate immune system? (Select all that apply)

Explanation

The innate immune system is the body's first line of defense against pathogens. Skin acts as a physical barrier, preventing the entry of microorganisms. Mucus traps pathogens and prevents them from reaching the body's tissues. Oils, produced by the skin, contain antimicrobial properties that help protect against infections. Tears contain enzymes and antibodies that can kill pathogens. Therefore, skin, mucus, oils, and tears are all barriers in the innate immune system.
