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.
<u>║ A ║ a</u>
<u>A ║ AA ║Aa</u>

Sterile powdered agar with nutrients can be mixed with water, heated and then poured into empty petri plates or ready-to-use dishes can be purchased. The undigestible agar is a gelatin-like substance with a semi solid surface on which the bacteria can grow while they consume the added nutrients (like sheep's blood).
Light speed in water is 2.25 times 10^5 m/s so the index of refraction is higher than the index of refraction of light in a vacuum which is 1.0. (speed in vacuum for light is 300,000 km/s)
Index of refraction of light in water is 3.0 time 10^5 m/s divided by 2.25 times 10^5 m/s = 1.33.
Hope this is what you wanted.
