Physics, Chemistry and Biology: Post your doubts here!

its of 2 marks so 2 points only to write
1. the sex of the fetus is determined by the 24th chromosome in the male gamete
2. if the gamete which fuses with femae gamete contain X chromosome so the fetus is female and if it contains Y so its male
( thx is cze female has XX chromosome and male have XY chromosome)

Thanks princess sofia

but why does the marking scheme say that this question is discounted

but why does the marking scheme say that this question is discounted

Because this question should have carried more marks. Like if it were for more marks, then you would have to discuss each and every case. However, they have only asked you a simple 2 mark question

q7 (a) how is it 4 V shdnt it b 6 V

Voltage is divided in a series circuit
Thus the current flowing is
12 = 6 * I
I = 2 A

The p.d across the 2 ohm resistor is
V = 2 * 2
V = 4V

Pholem perhaps!!!

Pholem perhaps!!!

No, it can't be phloem. Phloem is a living tissue that carries out active transport.
