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

63% Answer Correctly

isotopes

products

reactants

ions


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.

What is the body's largest artery?

72% Answer Correctly

arteriole

vena cava

capillary

aorta


Solution

The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.

"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." This describes which of Newton's laws of motion?

64% Answer Correctly

first

second

fourth

third


Solution

Newton's second law of motion states that The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This law basically means that the greater the mass of an object, the more force is needed to overcome its inertia.


4

Leafy vegetables, beans, potatoes, fruits, and whole grains are good sources of:

82% Answer Correctly

unsaturated fat

saturated fat

protein

fiber


Solution

Fiber provides bulk to help the large intestine carry away waste. Good sources of fiber are leafy vegetables, beans, potatoes, fruits, and whole grains.


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.
