Ans.
Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.

- <em>Neurons</em> are the cells of the nervous system that transmit and receive nerve impulses.
- The basic structure of a neuron consists of the <em>cell body, the axon, and the dendrites. </em>
- The<em> cell body</em> consists of the nucleus and thus contains the genetic material of the neurons. Emerging out from this are 2 types of extensions - dendrites and axon.
- The <em>dendrites</em> are involved in receiving messages from the other neurons whereas the <em>axon</em> is responsible for conducting the electrical impulses away from the cell body.
