Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:

58% Answer Correctly

1 m/s to a mass of 1 kg

1 m/s2 to a mass of 1 kg

1 mph to a mass of 1 kg

1 m/s2 to a mass of 1 kg/s2
Solution

Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.

Regulation of heart rhythm occurs in:

61% Answer Correctly

medulla

nerves

cerebellum

cerebrum

76% Answer Correctly

46

23

2

4
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.

5
