1

Which part of the respiratory system helps protect against infection?

53% Answer Correctly

epiglottis

trachea

nasal cavity

pharynx
Solution

After air enters through the nose, it passes through the nasal cavity which filters, moistens, and warms it. Further filtering takes place in the pharynx, which also helps protect against infection, and then in the trachea which is just past the epiglottis, responsible for preventing food from entering the airway.

What part of the brain is responsible for for balance, movement, and muscle coordination?

70% Answer Correctly

cerebrum

cerebellum

brainstem

Solution

The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.

3

Plant cells may generate energy through which of the following?

72% Answer Correctly

photosynthesis

aerobic respiration

anaerobic respiration

all of these
Solution

Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.

4

Which of the following describes the Earth's outer core?

45% Answer Correctly

solid

liquid

primarily solid

makes up most of the Earth's volume
Solution

The Earth's core is divided into the liquid outer core (1,430 miles or 2,300 km radius) and the solid inner core (745 miles or 1,200 km radius).

5

Which of the following represents the largest value?

61% Answer Correctly

1 mL

1 kL

1 cL

1 ML
Solution

Mega (M) is 106, kilo (k) is 103, centi (c) is 10-2, milli (m) is 10-3 so 1 ML represents the largest value.
