Answer:
we cant see the statement
Explanation:
<em>It’s one of the big mysteries of cell biology. Why do mitochondria—the oval-shaped structures that power our cells—have their own DNA, and why have they kept it when the cell itself has plenty of its own genetic material? A new study may have found an answer.</em>

Yes, it’s possible. The genetic that they give out to their children depends. If the parents gives out the genes for colorblind for the daughter but not the son, it’s possible.
It’s just like having a child with disabilities and another child that is perfectly healthy.
Answer:
D. A positive charge, because of a covalent bond with oxygen
Explanation:
A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.
