Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The HIV virus specifically targets and destroys CD4+ helper T cells, which are crucial for the immune system to function correctly.

Multiple choice

A virus that can reproduce without killing its host is called a

  1. Retroactive virus

  2. Lytic virus

  3. Virion

  4. Temperate virus
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Certain viruses, particularly bacteriophages, are called temperate (or latent) because the infection does not immediately result in cell death. The viral genetic material remains dormant or is actually integrated into the genome of the host cell.

Multiple choice

The functioning of which system of our body is damaged during the HIV infection.

  1. Nervous system

  2. Respiratory system

  3. Immune system

  4. Muscular system
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

HIV (Human Immunodeficiency Virus) specifically targets and destroys CD4 positive T cells, which are a crucial component of the human immune system. This leads to a weakened immune system, making the body susceptible to opportunistic infections.

Multiple choice

The AIDS virus does not spread through _________.

  1. infected mother to baby during pregnancy

  2. breastfeeding from an infected female

  3. blood to blood contact with infected person

  4. handshaking
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

HIV is not transmitted through casual contact such as handshaking, hugging, or sharing utensils.

Multiple choice

  1. Acquired infection disorder

  2. Acquired immunodeficiency syndrome

  3. Acquired immunodeficiency symptoms

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Acquired immunodeficiency syndrome

Multiple choice

The HIV virus mainly affects the

  1. Monocyte

  2. Basophile

  3. Neutrophil

  4. T-Lymphocyte

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

HIV (Human Immunodeficiency Virus) primarily targets and destroys CD4+ T-lymphocytes, which are essential components of the immune system.
