The correct Answer is:
To determine which statements are not incorrect, we will analyze each statement one by one: 1. **Statement (i)**: "Liver, the largest gland in our body secretes cholesterol, degrade steroid hormones, vitamins and drugs." - **Analysis**: This statement is true. The liver is indeed the largest gland in the human body and plays a crucial role in metabolizing and secreting cholesterol, degrading steroid hormones, and processing vitamins and drugs. 2. **Statement (ii)**: "Sebaceous glands eliminate certain substances like urea, sterols and sebum." - **Analysis**: This statement is also true. Sebaceous glands do produce sebum, which contains various substances including sterols, and they can eliminate some waste products, although urea is not their primary function. 3. **Statement (iii)**: "Sweat produced by sweat glands in an oily fluid containing NaCl." - **Analysis**: This statement is false. Sweat produced by sweat glands is primarily a watery fluid, not oily. It does contain NaCl (sodium chloride), but the description as "oily" is incorrect. 4. **Statement (iv)**: "In uremic patients urea and glucose can be removed by a process called hemodialysis." - **Analysis**: This statement is true. Hemodialysis is a medical procedure that removes waste products, including urea, from the blood of patients with kidney failure. In diabetic patients, glucose can also be present and can be removed during this process. Based on the analysis: - Statements (i), (ii), and (iv) are true (not incorrect). - Statement (iii) is false (incorrect). **Conclusion**: The statements that are not incorrect are (i), (ii), and (iv). **Final Answer**: The correct statements are (i), (ii), and (iv). ---

  • Read the given passage and answer the questions that follows: Rhodinus, a blood-sucking bug, shows five instars before it metamorphoses into an adult. It ahs a very long head with the brain located at tip and an organ called Corpora Cardiaca (C C) behind it. The hormone that ensures the continuum of the juvenile stages is called a juvenile hormone. Behind the head is a pro - thoracic gland, which gets triggered by the Pro - Thoracico - Tropic Hormone (PTTH) to release ecdysone required for molting into an adult. The following observations were made when the juveniles of this insect were subjected to various conditions : 1. Starved juveniles (any instar) when decapitated rarr remained juveniles and did not molt into adults. 2. Well-fed juveniles (any instar) when decapitated rarr molted into adults. 3. Starved juveniles (any instar) when partially decapitated to remove the brain cells rarr remained juveniles and did not molt into adults. 4. Well - fed juveniles (any instar) when partially deitated to remove the brain cells rarr did not molt into adults. Which of the following conclusions can be drawn from this data ? (i) Ecdysone hormone is produced irrespective of the level of feeding. (ii) C C is the site of production of juvenile hormone. (iii) PTTH is produced irrespective of the level of feeding. (iv) Increase in juvenile hormone is an important trigger for production of PTTH. (v) Absence of C C alone is a trigger for molting into adult form. (vi) Well-fed larvae in absence of juvenile hotmone can molt into adults.
