One parent with A and another with B can produce a child with A, B, AB or O blood types.
If one parent has A and another has AB, they can either produce a child with A, B or AB blood types.

Explanation:
continues to exist on the surface of Earth because the planet is at a distance far enough from the Sun that it does not lose its water to the runaway greenhouse effect, but not so far that low temperatures cause all water on the planet to freeze.
The plates carry the continents which make up the ocean floor, floating like islands on the hot, taffylike rock below.
A s solution that has more OH- than H+ is known as a basic solution.
<h3>What is an hydroxide ion (OH-)?</h3>
A hydroxide ion is a chemical ion the contains ions of hydrogen and oxygen with - 1 as it's oxidation number.
When a compound that contains excess OH- is added to a solution it will cause an increase in the basic nature of the solution.
This is because the OH- has the ability to accept protons when in a aqueous solution thereby leading to the rise in pH of that solution.
Increase in pH of a solution signifies an increase in basic characteristics.
