The correct answer is: D. Oxygen has more protons than hydrogen and water's shared electrons are drawn to it
In water (H2O), each hydrogen atom has one positively-charged proton surrounded by a 'cloud' of one negatively-charged electron. The oxygen atom has a nucleus with eight positively-charged protons, eight uncharged neutrons and eight negatively-charged electrons. Two electron pairs of oxygen are forming covalent bonds with hydrogen, while other two pairs are lone pairs. The eight positive charges in the oxygen attract electrons strongly and this leaves the hydrogen atoms partially positively charged, and the oxygen atom partially negatively charged.
The offsprings or children would be very similar to their parents.
Cross over involves the exchange of chromosomes segments between non-sister chromatids during the process of meiosis. It creates new combinations of genes in the gametes that are not found in either parent, a factor that brings about genetic variation or genetic diversity among individuals. Therefore, without crossover offsprings would be genetic similar with their parents.
Aldosterone is the right answer
