The correct Answer is:
### Step-by-Step Solution: 1. **Identify the Organism**: The question refers to the female Anopheles mosquito, which is known to be a vector for malaria. 2. **Understand the Process**: When the female Anopheles bites a human, it injects saliva into the bloodstream. This saliva contains anticoagulants that prevent blood clotting, allowing the mosquito to feed more easily. 3. **Link to Malaria**: The primary reason for the mosquito injecting saliva is to facilitate the transmission of the malaria-causing parasite, Plasmodium. 4. **Transmission of Plasmodium**: The Plasmodium parasite exists in the mosquito's salivary glands in the form of sporozoites. When the mosquito bites, these sporozoites are released into the human bloodstream. 5. **Conclusion**: The purpose of the female Anopheles pouring its saliva while biting is primarily to release sporozoites into the human body, which is essential for the transmission of malaria. ### Final Answer: The female Anopheles pours its saliva while biting the skin of a man to release sporozoites, which are necessary for the transmission of malaria. ---

When a female Anopheles mosquito bites an infected person, the parasite enter the mosquitoes bodies in many forms. Which of these is the infective form for mosquito? (a) Sporozoite (b) Gamete form (c) Gametocyte (d) All of these

Study carefully the following stages of life cycle of malarial parasite i.e., Plasmodium. Arrange these stages in the correct sequence and select the correct answer. 1. Sporozoites leave the blood stream and enter the liver cells of man. 2. Sporozoites present in the salivary glands of female Anopheles mosquito are injected into the blood stream of man. 3. The parasite reproduces asexually in RBCs, resulting in bursting of RBCs and causing the cycles of fever, relased parasites infect new RBCs. 4. The parasite reproduces asexually in liver cells, ultimately causing the rupturing of cells. 5. Two types of gametocytes i.e., microgametocytes and macrogametocytes develop in the RBCs. 6. Female Anopheleles mosquito takes up the gametocytes with blood meal of an infected person. 7. Mature infective stage of the parasite i.e., sporozoites escape from intestine and migrate to the mosquito's salivary glands. 8. Fertilisation and developmental stages of the parasite take place in mosquito's stomach.

Assertion . Sporozoites of malaria parasite enter human body by biting of new born female Anopheles whose mother was carrier . Reason. Male and female gametocytes of malaria parasite develop in human intestine.

A 90-kg man runs up an escalator while it is not in operation in 10s . What is the average power developed by the man. Suppose the escalator is running so that the escalator steps move at a speed of 0.5m^-1 . What is then the power developed by the man as seen by the ground reference if he moves at the same speed relative to the escalator steps as he did when the escalator is not in operation?
