1

The large intestine does which of the following?

82% Answer Correctly

breaks down starches

breaks down proteins

processes the physical waste produced by digestion

breaks down fats


Solution

The large intestine (colon) follows the small intestine and processes the physical waste produced by digestion, absorbing water and minerials that remain back into the body. Solid waste is then stored in the rectum while liquid waste is stored in the bladder.


2

Someone who has Rh-factor __________ blood cannot receive blood with a __________ type.

57% Answer Correctly

positive, negative

negative, positive

antigen, negative

positive, antigen


Solution

Blood transfer is limited by the type and Rh factor of the blood. Someone who has Rh-factor negative blood cannot receive blood with a positive type but a person with Rh-factor positive type blood can receive Rh-negative blood. Type O negative blood is the universal donor because it can be given to a person with any blood type. Type AB positive is the universal recipient meaning someone with this blood type can receive any other type of blood.


3

Which of the following is the formula for power?

56% Answer Correctly

\(P = w t\)

\(P = {w \over t}\)

\(P = {\vec{w} \over t}\)

\(P = \vec{w}t\)


Solution

Power is the rate at which work is performed or work per unit time:  \(P = {w \over t}\)  and is measured in watts (W).


4

Which of the following describes the Earth's mantle?

81% Answer Correctly

makes up most of Earth's volume

all of these

dense

hot


Solution

Mantle makes up 84% of the Earth's volume and has an average thickness of approximately 1,800 miles (2,900 km). It is dense, hot, and primarily solid although in places it behaves more like a viscous fluid as the plates of the upper mantle and crust gradually "float" along its circumference.

"An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." This describes which of Newton's laws of motion?

73% Answer Correctly

third

fourth

second

first


Solution

Also known as the law of inertia, Newton's first law of motion states that An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
