Class : Class 1

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.

It’s not mentioned about tightness of the circuits.

Ans 4: (Master Answer)

Admin from revisewise, Noida
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.
