The best answer to this question is c because a chemical change is when the original substance is changed into something else. If you boil water, it is still water. If you melt an ice cube, the water that made the ice cube is still water. Dissolving 10 grams of salt into changes the water and salt into a combined new solution. Splitting water into hydrogen and oxygen still gives you the original substances that made up the water molecule, so there was not any chemical change. 

Your answer should be:
C. dissolving 10 grams of salt in water

frosja888 [35]

Answer;

-Zygote

When sperm and ovum unite at conception, a zygote results.

Explanation;

-Conception occurs when a sperm cell from a fertile man swims up through the vagina and into the uterus of a woman and joins with the woman's egg cell (ovum) as it travels down one of the Fallopian tubes from the ovary to the uterus.

-A zygote is the union of the sperm cell and the ovum. Also known as a fertilized ovum, the zygote begins as a single cell but divides rapidly in the days following fertilization. After this two-week period of cell division, the zygote eventually becomes an embryo.
