1

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

58% Answer Correctly

1 m/s2 to a mass of 1 kg

1 mph to a mass of 1 kg

1 m/s 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.

2

The energy posessed by a ball on the window ledge of a tall building is an example of what kind of energy?

66% Answer Correctly

inherent

potential

kinetic

gravitational
Solution

Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.

3

Gametes have how many pairs of chromosomes?

76% Answer Correctly

23

2

4

46
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.

4

The __________ nervous system controls voluntary actions.

52% Answer Correctly

central

autonomic

peripheral

somatic
Solution

Part of the peripheral nervous system, the somatic nervous system is made up of nerve fibers that send sensory information to the central nervous system and control voluntary actions.

5

During continental drift, the drifting plates move across which of the following?

50% Answer Correctly

fault lines

liquid mantle

sediment

water
Solution

The crust and the rigid lithosphere (upper mantle) is made up of approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.
