A student observed the image and concluded that this image is depicting respiration in plants. Is the claim made by the student correct?
Yes; this structure is stomata, which helps the plant to take in oxygen from the soil
Yes; this structure is root hair, which helps the plant to take in oxygen from the soil
No; this structure is tracheae, which helps the earthworms to take in oxygen from the soil
No; this structure is a spiracle, which helps the cockroaches to take in oxygen from the soil
An experiment was conducted in a class where students were asked to blow air into a test tube containing lime water with the help of a straw. The observation of the experiment is shown in the image. What turns the lime water cloudy?
Reaction of oxygen gas present in the exhaled air with lime water
Reaction of all gases present in the atmosphere with the lime water
Reaction of nitrogen gas present in the atmosphere with the lime water
Reaction of carbon dioxide gas present in the exhaled air with lime water

Rib Cage
Diaphragm
Bronchi
Ramesh did a heavy exercise continuously for 3 hours, and then after sometime, he experienced muscle cramps. What could be the reason for experiencing cramps in muscles?
Temporary deficiency of oxygen in muscle cells
Permanent deficiency of oxygen in muscle cells
Temporary deficiency of carbon dioxide in muscle cells
Permanent deficiency of carbons oxide in muscle cells
The table shows the concentration of oxygen and carbon dioxide in the blood of two individuals. If the normal blood oxygen level varies between 75 and 100 mm of Hg, and normal blood carbon dioxide level varies between 38 to 42 mm of Hg, what can be said about the breathing rate of both individuals?
Individual A will breath faster than individual B
Individual B will breath faster than individual A.
Individual A and individual B both will breathe at the same rate
Individual A and individual B both will breathe at a slower rate
The percentage of carbon dioxide is higher in inhaled air in comparison to exhaled air.
True
False
Our muscle cells do anaerobic respiration only when there is temporary deficiency of oxygen.
True

People use different methods to get rid of nose hairs such as trimmers, waxing, and many more. However, some health specialists are against the idea of removing nose hair. What likely is the concern regarding the removal of nose hairs?
It may affect the sensitivity of the nose for odour.
The amount of inhaled oxygen will be affected.
Germs and foreign particles will get entry inside the body easily
It may lead to the production of mucous in excessive amounts inside the nose.

Whenever we feel drowsy or sleepy, we start yawning. Why?
When we feel the sleepy rate of respiration slows down. Because of this lungs will not get enough oxygen and we yawn.
Out of Syllabus
Yawning provides extra carbon dioxide to the body which helps us in staying awake
Yawning provides extra nitrogen to the body which helps us in staying awake
A food stall owner was preparing dough for making bhaturas. He added a pinch of yeast and sugar to the dough and left it in a warm place. After few hours, the dough had risen. There was a sour smell too. Why did the dough rise?
CO2 produced by yeast during respiration makes the dough rise
O2 produced by yeast during respiration makes the dough rise
Nitrogen produced by yeast during respiration makes the dough rise
Hydrogen produced by yeast during respiration makes the dough rise
