Answer:

Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys. Calcium is essential to all living things, particularly for the growth of healthy teeth and bones. Calcium phosphate is the main component of bone. The average human contains about 1 kilogram of calcium.

What are two ways scientists get information about the evolutionary history of a species
Serggg [28]
One way is by comparative anatomy. Comparing the similar bone structure of animals gives more proof of this theory. Also, the location of some animals compared to other animals of similar species is very convenient, and supports the theory of natural selection.

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children
vova2212 [387]

Answer:

He should request type O on his dating survey.

Opine's blood type must be AO to have a higher probability of producing O offsprings.

Explanation:

O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.

O blood type results are possible thanks to OO genotypes.

If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.

As regards the mother, her blood type should be OO.

We can see this more clearly in Punnet Square.

<u> ║ A ║O</u>

<u>O║AO║OO</u>

<u>O║AO║OO</u>  

There is a 50% of probability of having O offsprings with AO and OO.

  <u>║ A ║A</u>

<u>O║AO║AO</u>

<u>O║AO║AO </u>

With AA and OO, the probability is 0%

 <u>║ A ║O</u>

<u>A║AA║AO</u>

<u>O║AO║OO</u>

With both parents having AO, blood the probability of having a OO offspring is 25%.

In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.
