Question

Metamorphosis of insects is regulated through hormone

• A. pheromone
• B. thyroxine
• C. eedysone
• D. all of these.

Answer 1

The Correct Option is C

The metamorphosis of insects is a crucial developmental process that is primarily regulated by specific hormones. Let's examine the options provided and identify which hormone plays a direct role in this process:

1. Pheromone: Pheromones are chemicals that insects and other animals use to communicate with each other. They influence the behavior of other individuals but are not directly involved in the regulation of insect metamorphosis.
2. Thyroxine: This hormone is primarily associated with the regulation of metabolism in vertebrates, including humans, and does not play a role in insect metamorphosis.
3. Eedysone (Ecdysone): Ecdysone is a steroid hormone that plays a pivotal role in regulating the molting and metamorphosis of insects. It triggers the process of shedding the old exoskeleton and transitioning through different life stages (e.g., larva to pupa to adult). This makes it the correct answer.
4. All of these: Since neither pheromones nor thyroxine are involved in insect metamorphosis, this option is incorrect.

Thus, the correct answer to the question is eedysone.

Ecdysone initiates and regulates the process of metamorphosis in insects, ensuring proper development through the various life stages. Its function distinguishes it from other hormones mentioned in the options.
