The question asks to identify the non-alcoholic beverage known as the 'Queen of Beverages'. This is a general knowledge question related to common cultural epithets given to popular beverages.
Correct Option: B) Tea
Tea is often referred to as the 'Queen of Beverages' due to its immense popularity, diverse varieties, rich cultural history, and widespread consumption across the globe. It is the second most consumed beverage in the world after water.
This question tests general knowledge about sports trophies and the sports they are associated with. To answer correctly, one needs to recall the specific sport linked to the Ibrahim Rahimtoola Cup.
Correct Option: C) Badminton
The question asks for the instrument used to measure blood pressure. This is a direct knowledge-based question related to common medical instruments.
Correct Option: C) Sphygmomanometer
A sphygmomanometer is a medical device used to measure blood pressure. It consists of an inflatable cuff, a measuring unit (mercury manometer, aneroid gauge, or electronic sensor), and a mechanism for inflation (a bulb and valve). It measures both systolic and diastolic blood pressure.
The question asks about the consequences of deforestation. We need to evaluate each given option to determine if it is a direct or indirect result of deforestation.
D) All the above — Deforestation has multiple severe environmental impacts, including reduced rainfall leading to droughts, increased surface runoff causing floods, and the loss of protective vegetation leading to soil erosion. Therefore, all the listed options are correct outcomes of deforestation.
The question asks about the element whose excessive intake leads to bone deformities. We need to identify which of the given options is known to cause skeletal problems when consumed in high amounts.
Correct Option: D) Fluorine
This question asks for the full form of the acronym "IOC". This is a factual recall question related to common abbreviations of Indian public sector undertakings or well-known entities.
Correct Option: B) Indian Oil Corporation
The question asks about the general direction of cyclones formed in the Bay of Bengal. This relates to the typical tracks of tropical cyclones in the Northern Hemisphere, influenced by global wind patterns and the Coriolis effect.
Correct Option: A) East to West
Cyclones in the Bay of Bengal, being tropical cyclones in the Northern Hemisphere, are primarily steered by the easterly trade winds in their initial stages. This results in a general movement from east to west, often towards the Indian subcontinent.
The question asks to identify a parasitic plant from the given options. A parasitic organism lives on or in another organism (its host) and benefits by deriving nutrients at the host's expense. We need to evaluate each option to determine if it fits this description.
Considering the options, while mushrooms are fungi and not true plants, they are the only option that exhibits a parasitic mode of nutrition among the choices provided, making them the most appropriate answer in this context.
C) Mushroom — Mushrooms are fungi. Fungi are heterotrophic organisms, meaning they cannot produce their own food through photosynthesis. Many fungi are saprophytic (decomposers), but a significant number are parasitic, deriving nutrients from living hosts. Therefore, a mushroom (representing fungi) can be parasitic.
The question asks about the byproduct released during photosynthesis. To answer this, we need to recall the overall chemical equation for photosynthesis and identify the substances produced.
Correct Option: A) Oxygen — During photosynthesis, plants take in carbon dioxide and water, and in the presence of sunlight, produce glucose (food) and oxygen. The oxygen is then released into the atmosphere.
To find the speed of the current, we first need to calculate the speed of the boat upstream and downstream. We will use the formula: \(\text{Speed} = \frac{\text{Distance}}{\text{Time}}\). Once we have these speeds, we can use the formulas for upstream and downstream speeds to find the speed of the current.
Calculate Upstream Speed:
Given: Distance upstream = 2 km, Time upstream = 10 minutes.
Convert time to hours: \[10 \text{ minutes} = \frac{10}{60} \text{ hours} = \frac{1}{6} \text{ hours}\].
Upstream speed (\(S_u\)) is:
\[ S_u = \frac{\text{Distance}}{\text{Time}} = \frac{2 \text{ km}}{\frac{1}{6} \text{ hr}} = 2 \times 6 \text{ km/hr} = 12 \text{ kmph} \]Calculate Downstream Speed:
Given: Distance downstream = 2 km, Time downstream = 6 minutes.
Convert time to hours: \[6 \text{ minutes} = \frac{6}{60} \text{ hours} = \frac{1}{10} \text{ hours}\].
Downstream speed (\(S_d\)) is:
\[ S_d = \frac{\text{Distance}}{\text{Time}} = \frac{2 \text{ km}}{\frac{1}{10} \text{ hr}} = 2 \times 10 \text{ km/hr} = 20 \text{ kmph} \]Calculate Speed of the Current:
Let \(V_b\) be the speed of the boat in still water and \(V_c\) be the speed of the current.
We know that:
Upstream speed: \(S_u = V_b - V_c\)
Downstream speed: \(S_d = V_b + V_c\)
To find the speed of the current (\(V_c\)), we can subtract the upstream speed from the downstream speed and divide by 2:
\[ V_c = \frac{S_d - S_u}{2} \]Substitute the calculated values:
\[ V_c = \frac{20 \text{ kmph} - 12 \text{ kmph}}{2} = \frac{8 \text{ kmph}}{2} = 4 \text{ kmph} \]Correct Option: A) 4 kmph
