The infectious stage of plasmodium that enters the human body is:
1. Sporozoites
2. Female gametocytes
3. Male gametocytes
4. Trophozoites
Statement I: | Autoimmune disorder is a condition where body defense mechanism recognized its own cells as foreign bodies |
Statement II: | Rheumatoid arthritis is a condition where body does not attack self cells |
1. | Acquired immunity is non-specific type of defense present at the time of birth. |
2. | Primary response is produced when our body encounters a pathogen for the first time. |
3. | Anamnestic response is elicited on subsequent encounters with the same pathogen. |
4. | Anamnestic response is due to memory of first encounter. |
