Answer:
In the 1960s, scientists found evidence that new material is indeed erupting along mid-ocean ridges. The scientists dived to the ocean floor in Alvin, a small submarine built to withstand the crushing pressures four kilometers down in the ocean. In a ridge’s central valley, Alvin’s crew found strange rocks shaped like pillows or like toothpaste squeezed from a tube. Such rocks form only when molten material hardens quickly after erupting under water. These rocks showed that molten material has erupted again and again along the mid-ocean ridge.
When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history. The last reversal happened 780,000 years ago. If the magnetic poles suddenly reversed themselves today, you would find that your compass needle points south.

Answer:
ADA is an enzyme that is used to breakdown the food chain.
Explanation:
ADA is also called adenosine deaminase. It is an enzyme. It is a purine metabolism. ADA is used to needed for the breakdown of the adenosine from the food chain. ADA is found in both small and large form. The enzyme presented in it has polypeptide chain. It is folded in eight strands.
The ADA contain zinc. It is found in deepest site and combined with five form such as 15, 17, 214, 295 and the substrate.
The ADA is is inversible dominates the adenosine. It is considered the key enzyme of the purine metabolism. ADA in human beings work for development and maintenance.
I Think the Answer
is D...Hopes this Helps <span />
Use binomial distribution with p=0.25, n=5, x=2
P(X=x)=C(n,x)p^x (1-p)^(n-x)
P(X=2)=C(5,2) 0.25^2 0.75^(5-2)
=10*0.0625*0.421875
=0.26367
So the probability of 2 of 5 children having type-O blood from these parents is 0.26367.
