Answer 1

Here are the answers with brief notes:

2) b) Cytokines — signaling proteins that coordinate immune cells.
13) b) Diabetes Type 1 — an autoimmune disease (immune attack on pancreatic β-cells).
14) d) All of the above — inflammation causes redness, swelling, heat (and pain).
15) b) Adaptive — slower to develop but antigen-specific and has memory.
16) b) Tears — contain chemical antimicrobials (e.g., lysozyme). (Mucus also has chemical antimicrobial components.)
17) b) B cells — part of the adaptive immune system (along with T cells).
