2: C, I don't think insulin gene expression is regulated by the amount of trimmed/untrimmed insulin within the cell. Other pathways are involved in that function. Insulin simply isnt usable by the body until it has been properly processed within the cell.

3: D, This can happen in cancer.

Answer:

C. "Because you have had one child with Tay-Sachs, you must each carry the allele. Any child you have has a 25% chance of having the disease

Explanation:

Tay-Sachs disease is an autosomal recessive disorder that means a child will acquire the phenotype or we can say disease only when both the alleles which cause disease are present in the child.

Here, in this condition neither parent has Tay-Sachs but they gave birth to a child who is suffering from the disease then it simply means that both the parents are carrier of this disease i.e. they both are heterozygous.

The cross and probability of healthy and diseased child is shown as under:

                          Mother        Father

Parents                    Tt               Tt

                              /        |          |     \

Off-springs         TT      Tt       Tt      tt

<u>Out of these 4 probable off-springs only 3 with genotype TT, Tt & Tt  will be healthy while the 1 with genotype tt will be diseased.</u><u> </u><u>So, the probability of diseased child is 1/4 which is 25%. </u>

Also, the birth of children is an independent event so if one child has already been born with this disease then it doesn't mean that the next 3 children will be healthy for sure i.e. birth of first child cannot influence the next child. In short we can also say that in the next birth, there is still 25% chance of the child being born with this disease because previous birth has nothing to do with next birth.

I believe you mean mid-ocean ridge?

If so, true.

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.

This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.
