Directions : In the following questions a statement of assertion (A) ...
Assertion (A): Pathogens are disease-causing organisms.
Reason (R): Salmonella typhi is a pathogenic virus causing tuberculosis.
Explanation:
- Pathogens: Pathogens are disease-causing organisms, such as bacteria, viruses, fungi, or parasites, that can invade the body and cause infections or diseases. They can disrupt the normal functioning of the body and lead to various symptoms and health issues.
- Salmonella typhi: Salmonella typhi is a bacterium that causes the infectious disease known as typhoid fever, not tuberculosis. Tuberculosis is caused by another bacterium called Mycobacterium tuberculosis. Both Salmonella typhi and Mycobacterium tuberculosis are pathogenic organisms, but they cause different diseases.
Analysis of Assertion and Reason:
- The assertion states that pathogens are disease-causing organisms, which is true.
- The reason states that Salmonella typhi is a pathogenic virus causing tuberculosis, which is incorrect. Salmonella typhi causes typhoid fever, not tuberculosis.
Conclusion:
- The assertion is true as pathogens are indeed disease-causing organisms.
- However, the reason is false as Salmonella typhi does not cause tuberculosis. Therefore, the correct answer is option 'C' - Assertion (A) is true, but reason (R) is false.
