How does the number of chromosomes in an organism's reproductive cells compare to the number of chromosomes in the organism's body cells? A.
The reproductive cells have the same number of chromosomes as the body cells.
B.
The reproductive cells have four times as many chromosomes as the body cells.
C.
The reproductive cells have half as many chromosomes as the body cells.
D.
The reproductive cells have twice as many chromosomes as the body cells.

answer is d

The reproductive cells of an organism also called the sex cells in either male or female undergo the process of meiosis to reduce the diploid number into a haploid number ie reduction into half the original number.

This is to ensure that during reproduction, with the coming together of haploid sex cells (both haploid sperm and the haploid egg cell). A diploid organism can be produced.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
