Rise in the water level from X to Y in the given experimental set-up demonstrates

A

aerobic respiration

B

anaerobic respiration

C

photosynthesis

D

transpiration pull

Text Solution

Verified by Experts

The correct Answer is:
A
Oxygen required for aerobic respiration is taken up from the air of the apparatus. Carbon dioxide released during aerobic respiration is absorbed by potassium hydroxide (KOH). Therefore, a partial vacuum us created in the conical flask. This causes the rise of water in the bent tube. That oxygen is consumed during aerobic respiration can be tested by taking a burning splinter into the conical flask, which gets extinguished.

Read the paragraph and answer the following question: You must be knowing about the high and low tides that occur regularly in the sea. The level of the sea water at any given location along sea shore increase and decreases twice a day at regular intervals. High and low tides occur at different times at places. The level of water in sea changes because of the gravitational force exerted by the moon. Water directly under the moon gets pulled towards the moon and the level of water there goes up causing high tide at that place. At two places on the earth at 90^(@) from the place of high tide, the level of water is minimum and low tides occur there. How many times the sea level at the coast change?
