FAQs on Role of Thyroxine in Metamorphosis Video Lecture - Zoology Optional Notes for UPSC
| 1. What is the role of thyroxine in metamorphosis? |  |
Ans. Thyroxine is a hormone that plays a crucial role in regulating the metamorphosis process in organisms such as amphibians. It controls the rate of metamorphosis by affecting the growth and development of various tissues and organs.
| 2. How does thyroxine influence the transformation of tadpoles into frogs? | |
Ans. Thyroxine stimulates the growth and development of tadpoles, leading to the transformation into frogs. It triggers the reabsorption of the tadpole tail, the development of hind limbs, and the remodeling of the digestive system.
| 3. What happens if there is a deficiency of thyroxine during metamorphosis? | |
Ans. A deficiency of thyroxine during metamorphosis can lead to developmental abnormalities in organisms. It may result in the incomplete transformation of tadpoles into adult frogs, causing issues with limb development and organ restructuring.
| 4. How does thyroxine production change throughout the metamorphosis process? | |
Ans. Thyroxine production increases significantly during the metamorphosis process, especially during the climax stage when the transformation from a larval form to an adult form occurs. This surge in thyroxine levels is essential for driving the rapid changes in the organism's body structure.
| 5. Can external factors influence the levels of thyroxine during metamorphosis? | |
Ans. Yes, external factors such as temperature, food availability, and environmental conditions can influence the levels of thyroxine during metamorphosis. These factors can impact the rate and success of metamorphosis in organisms by affecting the production and activity of thyroxine.
