Groundwater may come out at some places to form water table. Select the incorrect option regarding this.

APrecipitate should be replaced with condense.
BCondenses should be replaced with evaporates.

IT IS 'D' BECAUSE AT COCOON STAGE THE CATERPILLAR PRODUCES SILK FIBRES AND KNOTS AROUND IT AND COVERS HIMSELF.AFTER SOME TIME THE SILK FIBRES GETS HARDEN DUE TO THE GUMMY SUBSTANCE WHICH THE CATERPILLAR PRODUCES............IT IS CALLED "FIBROIN" WHICH IS MADE UP OF PROTEINS.ON HEATING THE COCOONS IN WATER THE SILK AGAIN BECOMES SOFT AND IS EXTRACTED FROM COCOONS........THIS PROCESS IS CALLED "REELING OF SILK"

OPTION C

Ans 3:

Class : Class 8

Ans 4:

Class : Class 8

Ans 5:

Class : Class 7
ans:c,you may think d,but only in larval stage it produce silk in option d it is in a cocoon stage it cannot produce silk

Ans 6:

Class : Class 7
I thought the silk is obtained from the cocoon

Ans 7:

Class : Class 7
the answer is d only in the cocoon stage they are heated in the hot water so that the reproducing caterpillar will die and it will be very easy to extract silk fiber from it.

Ans 8:

Class : Class 8
as larva produces and when it is fully produced it forms a cocoon

Ans 9:

Class : Class 7
it is c because the silk has already started getting produces when it is larva

Ans 10:

Class : Class 8
No, the answer is 'C' only. In pupa stage the silk fiber is only obtained, but actually it is produced by larva and in question it is asked which stage produces fiber. Hence, the answer is 'C".

Ans 11:

Class : Class 7

Ans 12:

Class : Class 7
it must be c . at cocoon stage silk is already produced
