AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Context**: The question asks about a substance that helps insects track others of their kind and raise alarms during dangerous situations. 2. **Understand Pheromones**: Pheromones are chemical messengers released by animals and insects. They carry information to others of the same species and can influence their behavior. 3. **Recognize the Function of Pheromones**: Pheromones help in communication among insects. For example, ants use pheromones to create a trail that others can follow, which is essential for finding food or navigating. 4. **Alarm Response**: In addition to tracking, pheromones can signal danger. When an insect detects a threat, it can release pheromones that alert others in the vicinity to the danger, prompting them to take action. 5. **Eliminate Incorrect Options**: The other options mentioned (Thyroxine, Calcitonin, Tri-Iodo Thyronine) are hormones that act as chemical messengers but are released inside the body and do not serve the same purpose as pheromones in communication among insects. 6. **Conclude with the Correct Answer**: The correct answer to the question is "pheromones," as they are the substances that help insects track their kind and raise alarms during dangerous situations. **Final Answer**: Pheromones help these insects to track more of their kind and to raise alarms during dangerous situations. ---

Akhtar, Kiran and Rahul were riding in a motorcar that was a high velocity on an expressway when an insect hit the windshield and got stuck on the windscreen . Akhtar and Kiran started pondering over the situation. Kiran suggested that the insect suffered a greater change in momentum as compared to the change in momentum of the motorcar (because the change in the velocity of the insect was much more than that of the motorcar). Akhtar said that since the motorcar was moving with a larger velocity, it exerted a larger force on the insect. And as a result, the insect died. Rahul while putting an entirely new explanation said that both the motorcar and the insect experienced the same force and a change in their momentum. Comment on these suggestions.

Read the following passage and answer the item that follow. PASSAGE-II On a surface which is free from obstacles, such as a clear road or a path, only two or three species of snakes can hope to catch up with a human being, even if they are foolish to try. A snake seems to move very fast but its movements are deceptive. In spite of the swift, wave-like motions of its body, the snake crawls along the ground at no more than the speed of man's walk. It may, however, have an advantage inside a jungle, where the progress of a man is obstructed by thorny bushes. But in such places, the footsteps of a man are usually more than enough to warn snakes to keep away. Although they have no ears of the usual kind, they can feel slight vibrations of the ground through their bodies, and thus get an early warning of danger. What helps the snakes to receive advance warning is their sensitivity to :
