The pH of seawater is about 8.1, making it alkaline.
The average pH of sea water is about 8.1 but it can also range between the pH value 7.9 to 9.0 as the result of the various activities that happen in the water. At this pH range, HCO3 ions are the major ions that are present, but as the pH of the water increases, the carbonate ions levels also increases, thus, when carbon dioxide dissolves in water it makes the water to become acidic.

Answer:
There is a 25% probability that their child will have Tay-Sachs disease.
Explanation:
We know that:
People that are homozygous for the Tay-Sachs allele die, that means that the two copies of that allele are affected.
The members of the couple are both carriers, which means that they are both heterozygous for the Tay-Sachs allele, so they did not die because only one copy of the allele's pair is affected.
If we make a Punnet square where A stands for the affected allele and a for the normal one, we can see that both members of the couple are Aa and that there is only a 25% of probability that their child will have Tay-Sachs disease, as well as a 50% chance of being a carrier.

Environmental and Genetic factors are both incredibly complex structures, but all will create mutations of the species. The genetic variability created by mutations will be tested by natural selection, which can and will determine which characteristics are inherited in a population over time.
