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.
You are driving in the left lane on a four-lane freeway and have to take the exit on the right. you should change one lane at a time to be in the exit lane.
There are every type of rules are for driving, so that what you should do in any situation. If everyone follows those rules and guidelines, the percentage of accidents became very low.
The main source of heat energy in the earth's inner core is radioactive decay, and the radiogenic heat producted by the radiogenic decay of isotopes in the mantle and crsut. I hope this helped

Explanation:
Meiosis is a type of cell division in which the ploidy of the organism reduces to half in the daughter cells.
Meiosis produces 4 daughter cells from 1 parent cell with a different combination of the genetic material but haploid chromosomes.
The meiosis process takes place in two stages in which during the first stage, the homologous chromosomes separate reducing the chromosome number to half that is from diploid chromosomes of parents to haploid in daughter.
Since the process of meiosis form haploid gametes in both male and female therefore after fertilization restores the diploid chromosomes of the parent cell and form a diploid structure.
