1

Meteoroids, meteors and meteorites are categorized based on which of the following?

45% Answer Correctly

their location

their size

their density

their temperature


Solution

Smaller rocks shed by asteroids and comets are called meteoroids. When these rocks reach Earth's atmosphere, they burn up in the mesosphere and become meteors. If a meteor manages to reach the Earth, it is called a meteorite.


2

Gametes have how many pairs of chromosomes?

76% Answer Correctly

23

46

4

2


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.


3

Which of the following is the correct order for types of radiation from lowest to highest frequency?

63% Answer Correctly

microwaves → radio waves → visible light

visible light → ultraviolet light → radio waves

infrared waves → microwaves → ultraviolet light

radio waves → visible light → gamma rays


Solution

The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation.  From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.


4

Which of these is important for the body's maintenance, growth, and repair?

88% Answer Correctly

fiber

carbohydrates

protein

fats


Solution

Found in both animal sources (meat, fish, eggs, cheese) and vegetables (beans, nuts, some grains), proteins are important for the body's maintenance, growth, and repair.
