6. What do the hair and mucus along the nasal cavity do?
Answer: c. They filter the dust and germs which enter the lower respiratory organ.
Explanation: The nasal hairs (vibrissae) and mucus trap dust, bacteria, and other particles, preventing them from entering the lungs.
---
7. Where does the exchange of gases take place?
Answer: b. lungs
Explanation: Gas exchange—oxygen entering the blood and carbon dioxide leaving—occurs in the alveoli of the lungs.
---
8. What do you call the female hormones?
Answer: b. estrogen
Explanation: Estrogen is the primary female sex hormone responsible for the development of female reproductive tissues and secondary sexual characteristics. (Note: Progesterone is another important female hormone, but "estrogen" is the best choice here.)
---
9. Which food waste contains bacteria, salt and undigested food?
Answer: a. Feces
Explanation: Feces are the solid waste material expelled from the body after digestion. It includes undigested food, bacteria, dead cells, and salts.
---
10. How are excess salts and minerals from the blood excreted?
Answer: d. by urination
Explanation: The kidneys filter blood and remove excess salts, minerals, and waste products, which are excreted as urine.
---
1. What are the main excretory organs of nitrogenous wastes?
Answer: Kidneys
Explanation: The kidneys filter nitrogenous wastes like urea from the blood and excrete them in urine.
---
2. What gas do you exhale?
Answer: Carbon dioxide
Explanation: During respiration, oxygen is taken in, and carbon dioxide—a waste product of cellular respiration—is exhaled.
---
3. What is a common ailment of the respiratory system caused by a virus tubercle bacilli?
Answer: Tuberculosis
Explanation: Tuberculosis (TB) is caused by the bacterium *Mycobacterium tuberculosis*, not a virus. (Note: There’s a small error in the question—it says “virus,” but TB is bacterial. However, the answer is still correct.)
