Select the correct statement from the following.

A If blisters are formed due to severe burn, they should be immediately pricked and vinegar should be applied on the burnt area.
B Toothpaste should be applied to the skin area where the snake has bitten and the victim should be positioned such that the bitten part lies above the level of heart.
C If a person is bleeding through nose he should be made to lie down flat on ground with head held back.
D Both A and B


Ans 1:

Class : Class 6
In option c, the person must bend head forward to let blood darin out through nose and not down the throat. So option c is wrong.Also sitting is better than lying, as if nose is above heart that reduces the pressure, so option C is terribly wrong

When the bar magnet moves, it is able to drag the match box along. What is most likely to be found in the matchbox?

A Marble

the match box should certainly contain something magnetic as, when the bar magnet is moved then the match box is also dragged along with it .

Ans 5:

Class : Class 7
