Question 6:

Let's check each statement about viruses:

A. Viruses are only reproduced inside an infected living cell and can cause cell damage
✅ Correct — Viruses are obligate intracellular parasites; they must enter a host cell to replicate, and this often damages or kills the cell.

B. Viruses can reproduce in the bloodstream unaided
❌ Incorrect — Viruses cannot reproduce outside a living cell; even in the bloodstream, they must enter a host cell (e.g., white blood cells) to replicate.

C. Viruses reproduce outside the body before causing disease internally when a high viral load exists
❌ Incorrect — Viruses cannot reproduce outside a living host; no replication occurs outside the body.

D. Viruses self-replicate unaided throughout the body and cause disease by producing toxins
❌ Incorrect — Viruses do not "self-replicate unaided"; they rely on host cell machinery. Also, viruses generally do not produce toxins (that's bacteria); they cause disease by damaging cells or triggering immune responses.

Question 7:

Let's check the correct transmission routes:

• Malaria — Transmitted by the bite of an infected female Anopheles mosquito → animal vector

• HIV — Transmitted through body fluids (blood, semen, vaginal fluids, breast milk) → body fluids

Now match with the rows:

• A. Malaria → water ❌ ; HIV → airborne ❌ → incorrect

• B. Malaria → animal vector ✅ ; HIV → airborne ❌ → incorrect

• C. Malaria → animal vector ✅ ; HIV → body fluids ✅ → correct

• D. Malaria → water ❌ ; HIV → body fluids ✅ → incorrect

Question 8:

Checking the options:

• A. measles and malaria ❌ — Malaria is not droplet.

• B. HIV and gonorrhoea ❌ — Neither is droplet.

• C. tuberculosis and measles ✅ — Both spread by droplets.

• D. cholera and salmonella ❌ — Both are typically water/foodborne, not droplet.

Answer: C ✅

Question 9:

Let's match each lifestyle choice with its common disease:

• Excessive alcohol consumption → Liver diseases (e.g., cirrhosis, alcoholic hepatitis)

• Smoking → Cardiovascular diseases (e.g., heart attack, stroke, hypertension)

Now check the rows:

• A. Alcohol → cardiovascular diseases ❌; Smoking → liver diseases ❌ → swapped, incorrect

• B. Alcohol → liver diseases ✅; Smoking → cardiovascular diseases ✅ → correct

• C. Alcohol → cardiovascular diseases ❌; Smoking → bowel diseases ❌ (smoking increases risk of bowel cancer but not the most common link — CVD is primary)

• D. Alcohol → bowel diseases ❌; Smoking → liver diseases ❌ (smoking does not primarily cause liver disease)

Answer: B ✅

Question 10:

The sentence describes Salmonella, which is a bacterium.
The symptoms are caused by the bacteria themselves and the toxins they secrete.

• A. bacteria ✅ — Correct, as Salmonella is a bacterium.

• B. viruses ❌ — Salmonella is not a virus.

• C. antigens ❌ — Antigens trigger immune responses but are not the cause here in the way the sentence is structured.

• D. protists ❌ — Salmonella is not a protist.

Answer: A. bacteria ✅
