1

Poor balance could indicate an issue with which part of the nervous system?

64% Answer Correctly

spinal cord

cerebrum

medulla

cerebellum


Solution

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


2

Convert 0C° to F°.

72% Answer Correctly

-32

0

16

32


Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(0) + 32\)

\(F° = 0 + 32 = 32\)

 


3

The heart __________ blood.

61% Answer Correctly

filters

oxygenates

creates

deoxygenates


Solution

To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.


4

Materials like metals that transfer heat efficiently are called:

83% Answer Correctly

conductors

reflectors

refractors

insulators


Solution

Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.


5

Atoms of an element whose atoms can vary in the number of neutrons in their nucleus are called which of the following?

64% Answer Correctly

isotopes

ions

products

reactants


Solution

The atomic mass of an element listed in the Periodic Table represents the average mass of a single atom of that element and is measured in atomic mass units (amu). This number is an average as some elements have isotopes with atoms that vary in their number of neturons and, therefore, differ in weight.
