question 2
1 pts
which substance can destroy pathogens by lowering the ph to a level at which they cannot function?
hydrochloric acid
mucus
enzymes
sebum

Explanation:

• Question 1: Lymph nodes are part of the lymphatic system. Inguinal lymph nodes are located in the groin area. Axillary lymph nodes are in the armpit. Submaxillary and submental groups are related to the neck and chin regions.
• Question 2: Hydrochloric acid (stomach acid) has a low pH (high acidity). It can destroy pathogens that enter the stomach. Mucus acts as a physical barrier. Enzymes can break down substances but not mainly by pH - lowering in this context. Sebum is an oily substance on the skin that has some antimicrobial properties but not through significant pH - lowering like stomach acid.

Answer:

• Question 1: inguinal lymph nodes.
• Question 2: Hydrochloric acid.
