Gametes have how many pairs of chromosomes?

76% Answer Correctly

	46
	23

Solution

Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.

As a cold front moves into an area, the heavier cool air __________ the lighter warm air that it is replacing.

65% Answer Correctly

	pushes above
	pushes under
	mixes with
	cancels out

Solution

A cold front is a warm-cold air boundary with the colder air replacing the warmer. As a cold front moves into an area, the heavier cool air pushes under the lighter warm air that it is replacing. The warm air becomes cooler as it rises and, if the rising air is humid enough, the water vapor it contains will condense into clouds and precipitation may fall.
