I thought of B but after checking the solution I got it that it's A only, so the answer is A

Ans 4:

Class : Class 10
correct answer should be option B because there is no change in the current passing through lamp Y.

Ans 5:

Class : Class 9

I agree with omkar,maitri,abhid etc all who are saying option B because we can read that another bulb 'Z' is connected in "PARALLEL" and not in "SERIES" and as we know , if we connect many bulb with same battery in a parallel circuit , they will give same brightness if the one bulb was connected , but the consumption of battery will also increase.So, according to me , there will be no change in bulb y (NORMAL)ans should be : option "A"

I think (A) is the answer because the explanation in the solution makes complete sense but technically it could also be (B)

Ans 18:

Class : Class 7
it is b only not c pls report an error

Ans 19:

Class : Class 6
The correct answer is B as the bulb Y is in straight series and there is no change of current passing through it. And the curent gets equally divided among X and Y.

Ans 20:

Class : Class 6
Shouldn't the answer be option B, because it makes the most sense. No electricity or amps or power is taken away from bulb Y. Why is it answer A?

Ans 21:

Class : Class 6

Ans 22:

Class : Class 7
It should be B as no change of current is there in Y.

Ans 23:

The scientific name of WBC is leukocyte. There are 5 types of leukocytes namely: Basophils , Eosinophil, Neutrophil, Lymphocyte. The scientific name of red blood cells is erythrocytes. Maybe there is no scientific name for platelets or it may appear that I don't know it.

Hi all, The pathogens of disease can be transferred from infected mother to the foetus only through placenta. it is because all the nutrients are poured into the body of the foetus by placenta in the womb. Placenta is the only biological connection between the mother and the unborn baby in the womb. The foetus is not out of the womb of the mother to feed through her breast milk.
