Genes<span> are made of a chemical called </span>DNA<span>, which is short for 'deoxyribonucleic acid'. The </span>DNA<span> molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase. The sides are sugar and phosphate molecules.</span>
Fungi has a cell wall, no chlorophyll in the cells (unlike plants), is multicellular, and eukaryotic
Its stabilising. Since the selection pressure is against the extremes which are the normal blood and the sickle cell anaemia.
Since fish feeds primarily on large amphipod,
therefore what we expect to remain to evolve on ponds containing fish would be
smaller amphipod or crustacean. Then correct answer to this question would be:
<span>“Ponds with fish should have smaller amphipods.”</span>
