Answer: The father determines the biological sex of a baby
Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.
What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.
Answer:
A warm front is moving towards South Carolina bringing rainy conditions
Explanation:
From this weather map, we can see that South Carolina will soon be under the influence of a warm front. The warm front is moving towards this state, and it is coming from southeastern direction, thus it has been formed over warm waters. Because it has been formed over warm waters, this front is warm and very moist which will result in lot of rainfall once it comes upon a natural barrier to cause condensation, and the Appalachian Mountains will do just that, thus South Carolina will receive a lot of rainfall.
