Answer:
option (a) because....,
Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). ... Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA)
option (b) not because,
Within that centrosome there are two centrioles. And centrioles are physical objects made up of things called microtubules.
option (c) not because....,
Centromere repeats in humans are made up of alpha-satellite DNA, a ∼171 bp sequence or monomer that is iteratively repeated. Alpha-satellite monomers are arranged head-to-tail and organized into repeated arrays called higher order repeats (HORs) that range from 0.2 to 5 megabases (Mb) and are chromosome specific.
not option (d) because...,

D. Watershed - a watershed is the area in which runoff, rivers, and streams run into a larger body of water
Assuming it is plain water and had normal air pressure it would stay 100 degrees Celsius having reached its latent heat of vapouristaion the extra energy added into the water in that 10min would go into turning the water into steam. Simplified: it would stay at the same temp
100 percent, because if both parents have the same genotype of Tt then most likely the child will have 100percent.
