1

During digestion, the kidneys filter substances from the blood. Which of the following is not filtered by the kidneys?

73% Answer Correctly

minerals

fats

water

salt


Solution

Chemical waste like excess water, minerals, and salt are filtered from the blood by the kidneys and secreted into the urine. Urine is transported from the kidneys to the bladder through ureters.


2

Acceleration is the rate of change of velocity per unit of time. Which of these is the formula for acceleration?

59% Answer Correctly

\(\vec{a} = { \Delta \vec{v} \over t }\)

\(\vec{a} = { \vec{v} \over t }\)

\(\vec{a} = \Delta \vec{v} t \)

\(\vec{a} = { t \over \Delta \vec{v} }\)


Solution

Acceleration is the rate of change of velocity per unit of time. In physics, the delta symbol (\(\Delta\)) represents change so the formula for acceleration becomes  \(\vec{a} = { \Delta \vec{v} \over t }\)


3

50°F is how many °C?

72% Answer Correctly

-10

122

58

10


Solution

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (50 - 32)\)

\(C° = {5 \over 9} (18)\)

\(C° = {90 \over 9}\)

\(C° = 10\)


4

Traits represented by genes may be which of the following?

82% Answer Correctly

dominant

recessive

expressed

all of these


Solution

The traits represented by genes are inherited independently of each other  (one from the male and one from the female gamete) and a trait can be dominant or recessive.  A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.


5

Antigens in the blood determine:

52% Answer Correctly

blood type

Rh factor

negative or positive status

blood oxygen capacity


Solution

Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.
