The correct answer is C.

Ram and Achin made the correct statements. Divya made an incorrect statement as the antelope population will be much more than the lion population in order to support the energy needs of the lion population. Ritu also made an incorrect statement because without the grass population, both antelope population and lion population will be negatively affected as lion feeds on antelope and antelope feeds on grass.

The correct answer is A.

When food is taken in the mouth, it is chewed and gets mixed with saliva secreted in the mouth (R). Once swallowed, the food moves through the oesophagus into the stomach where churning and digestion of food with digestive juices occurs (Q). The semi-digested food then moves into the small intestine where complete digestion as well as absorption of nutrients occur (S). From the undigested food, the water is absorbed in the large intestine (P). After this, the undigested food is expelled through the anus in the form of faeces (T).

there is no necessity of mentioning the words: "descending order". This is contradictory to the statement: A>B>C>D. Hence the question is wrong.

The answer can either be B or D.

Ans 13:

That answer is D as b,a and b are the best conductors of heat so the heat would pass through b,a and b faster and it is balanced.Nice question.

I also didn't understand the question.

Ans 4:

Class : Class 6
Why is the answer D? This is because it says that woodlice are found typically under damp rotting leaves. For the test, Sanika kept rotting leaves on dry and damp soil. If you read the question carefully, you will find that Sanika had stated that woodlice needed a damp environment as a possible explanation as to why woodlice were found under damp rotting leaves. She even placed the woodlice pointing to the rotting leaves with damp soil under it. Based on this, she was most probably testing the 4th explanation she stated and so that, my friends, is why option D is the correct answer.
