The correct answer is A.

Both plants ‘c’ and ‘d’ bear fruits. This means they are flowering plants as only flowers change into fruits. Plant ‘c’ grows in water i.e., it is an aquatic plant but plant ‘d’ does not grow in water thus, it is a nonaquatic plant. Hence 'W' and 'X' represent plant ‘c’ and ‘d’ respectively.

How can a liquid be equal to a battery and another liquid be equal to *its* cell?

Ans 2:

Class : Class 8
Yes.. Tightness is not mentioned.

Ans 3:

Class : Class 8
It’s not mentioned about tightness of the circuits.

Ans 4: (Master Answer)

Class : Class 1

The correct answer is B

In given figures, both the circuits are tightly connected and both the liquids conduct electricity because both the bulbs are glowing. The bulb in the set up P glows more brightly as compared to that of the set up Q might be because of any of the two possibilities:

1. The liquid in Q may have small conductivity. 

2.  Liquid in P is equivalent to a battery while liquid in Q is equivalent to a cell of the battery of liquid P

Ans.- (A) The buggy pulls the horse as backward just as hard the horse pulls the buggy forward. According to the IIIrd law of NLM( Newton's Laws of Motion), the action and reaction force takes place in two different bodies, in different direction , but of the same magnitude.

Ans 6:

Class : Class 8
Answer A will be correct if you take newtons third law of motion into consideration

Ans 7: (Master Answer)

Class : Class 1

The correct answer is B.

In the given Venn diagram X, Y and Z represent vitamin D, vitamin E and vitamin K, respectively. Deficiency of vitamin A causes night blindness and deficiency of vitamin C causes scurvy. Pellagra is caused by deficiency of vitamin B3. Vitamin B is a group of several vitamins like B1, B2, B3, B6, B12 and folic acid and is known as vitamin B complex.
