The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion (A)**: - The assertion states that a jar for nutrient solution culture has a split cover with holes that hold a bent tube for aeration. - This setup is typically used in hydroponics, which is a method of growing plants without soil, using a nutrient solution instead. 2. **Understanding the Reason (R)**: - The reason states that regular aeration of the culture solution is necessary for the proper growth and activities of roots. - Aeration is crucial because it allows for the exchange of gases, which is essential for root respiration. 3. **Analyzing the Assertion**: - The assertion is true. The design of the jar with a split cover and bent tube is indeed meant to facilitate aeration in hydroponic systems. - The holes in the cover allow air to enter the solution, which is vital for the health of the roots. 4. **Analyzing the Reason**: - The reason is also true. Roots require oxygen for respiration, which is necessary for their growth and metabolic activities. - Without sufficient aeration, roots cannot perform respiration effectively, leading to a lack of ATP production, which is critical for their survival and function. 5. **Connecting Assertion and Reason**: - The reason provided correctly explains why the assertion is true. The aeration system in the jar is designed specifically to ensure that the roots can respire properly, which is essential for their growth. 6. **Conclusion**: - Both the assertion and reason are true, and the reason provides a correct explanation for the assertion. - Therefore, the answer is: **Option 1 - Both assertion and reason are true, and the reason is the correct explanation of the assertion.**

A small aquatic plant was put in each of the petri dishes X and Y containing different culture solutions. After six weeks, the plant in dish X had the same number of leaves as earlier, and all leaves were small and yellowish. The plant in dish Y had more leaves of normal size and dark green colour. Which of the following set of elements would be missing in the culture of dish X ?

Which of the following statements regarding eutrophication are correct ? (i) Eutrophication is the natural ageing of a lake by nutrient enrichment of its water. (ii) Pollutants from human activities like effluents from the industries and homes can radically accelerate the aging process of a lake. This phenomenon is called as cultural or accelerated eutrophication. (iii) The plant nutrients responsible for eutrophication are nitrates and phosphates. (iv) These phosphates and nitrates accelerate the growth of algae, which utilise oxygen and may deoxygenate the water to kill the fish and other aquatic animals.

The system shown in the figure is in equilibrium, where A and B are isomeric liquids and form an ideal solution at TK . Standard vapour pressures of A and B are P_(A)^(0) and P_(B)^(0) , respectively, at TK . We collect the vapour of A and B in two containers of volume V , first container is maintained at 2 T K and second container is maintained at 3T//2 . At the temperature greater than T K , both A and B exist in only gaseous form. We assume than collected gases behave ideally at 2 T K and there may take place an isomerisation reaction in which A gets converted into B by first-order kinetics reaction given as: Aoverset(k)rarrB , where k is a rate constant. In container ( II ) at the given temperature 3T//2 , A and B are ideal in nature and non reacting in nature. A small pin hole is made into container. We can determine the initial rate of effusion of both gases in vacuum by the expression r=K.(P)/(sqrt(M_(0))) where P= pressure differences between system and surrounding K= positive constant M_(0)= molecular weight of the gas If vapours are collected in a container of volume 8.21 L maintained at 3 T//2K , where T=50 K , then the ratio of initial rate of effusion of gases A and B is given as
