Quiz Answer Key and Fun Facts

1. The sex chromosome of a human female is XY.

Answer: False

The sex chromosome of a human female is XX. The human male, on the other hand, has the sex chromosome of XY.

2. In kilohertz, what is the frequency of a wave traveling at 2.5 microseconds?

Answer: 400kHz

The frequency is the inverse of a time period in seconds. The inverse of 2.5 microseconds is written as (1,000,000/2.5), which is equal to 400,000Hz (or 0.4 Megahertz). One kilohertz is equal to 1000 hertz, so to convert to kilohertz, you divide 400,000Hz by 1000 to get 400kHz.

3. White blood cells carry oxygen.

Answer: False

White blood cells fight infection. Red blood cells are the ones that carry oxygen.
