Anterior muscle is located near the front of the body. Of those listed, the quadriceps is the most anterior

So, the answer is option "d"

2. The lateral side of the right knee would be:

a. the kneecap
b. closest to the left knee
c. farthest from the left knee.
d. on the underside of the knee

Something that is lateral is toward the outer side of the body. The side of the right knee farthest from the left knee would fit this description

So here the answer is option "c"

3. The ovaries are part of the ________system.

a. skeletal
b. nervous
c. lymphatic
d. reproductive

The ovaries are the egg-producing reproductive organs

So here the answer is option "d"

4. The headrest on a car may prevent traumatic injury by limiting:

a. hyperflexion of the neck
b. hyperextension of the neck
c. vertebral compression
d. disc degeneration

The headrest prevents the head from moving too far backward or hyperextending the neck beyond its normal range

So here the answer is option "b"

5. In a whiplash injury, you might expect to see:

a. cardiopulmonary problems
b. side-to-side spinal curvature
c. eventual injury to ligaments
d. traumatic injury to ligaments

Because of the hyperflexion and hyperextension caused by such a collision, it is not uncommon to find tears or stretching of ligaments of the spine. The injury is front to back

So here the answer is option "d"

6. When a junked car is compacted, which statement is true?

a. it's mass increases
b. its mass decreases
c. its density increases
d. its density decreases

Since density = mass/volume, it should be obvious that the decrease in volume as a car is crushed should lead to an increase in density. Nothing happens to change the mass of the car.

So here the answer is option "c"

7. Which is an example of deductive reasoning?

A. Ten of the 100 applicants are left-handed; therefore 10% of the general population must be left-handed
B. I know several left-handed artists; therefore left-handed people must have the artistic aptitude
C. Left-handed people are artistic; Jon is left-handed. Therefore, John must be artistic.
D. I see that Jon is left-handed. Jon is a gifted artist. Therefore left-handed people must be gifted artists.

In deductive reasoning, a hypothesis follows from a set of premises. The premises may be true, in which case the reasoning is sound, or they may be untrue or at least dubious, as in this example.

so here the answer is option "c"

8. If gas A has four times the molar mass of gas B, you would expect it to diffuse through a plug:

a. at half the rate of gas B
b. at twice the rate of gas B.
c. at a quarter the rate of gas B.
d. at four times the rate of gas B
Set up as a simple equation if it helps - Suppose that gas A has a molar mass of M1 and gas B has a molar mass four times that M2. Now suppose that that M1 = 1, and M2 = 4. The square root of 4/1 = 2/1 so the rate of effusion for gas A is half that of gas B

So here the answer is option "a"

9. What is the percent by volume of ethanol in 120ml of a solution containing 35ml of ethanol dissolved in water?

a. 22.6%
b. 29.2 %
c. 35%
d. 41.1%
Essentially you are determining the concentration as if it were in a 100ml solution, which is what percent really means. You could set up the equation:
35/120 = x/100
3500/100x
x = 29.2

So here the answer is option "b"

10. Three students measured the mass of a product of combustion. They recorded measurements of 5.14g, 5.16g, and 5.17g. If the known mass of the product is 5.3g, the students measurements were _____________?

a. accurate
b. precise
c. both precise and accurate
d. neither accurate or precise
The student's measurements were precise in that they correspond closely with one another. However, since the true measurement differed from theirs by at least .13g, the measurements were not terribly accurate.

So here the answer is option "b"

11. Which would not be a likely component of quantitative investigation?

21. Which ion would you expect to dominate in water solutions of bases?

a. MgCl2
b. 2HCl
c. H+
d. OH-

As a general rule of thumb, for acid solutions [H+] > [OH-] for basic solutions [H+] < [OH-] and for neutral solutions or for pure water [H+] = [OH-]

So here the answer is "d"

22. Why doesn't a raindrop accelerate as it approaches the ground?

a. gravity pulls it down at a constant rate
b. air resistance balances gravitational force
c. it's mass decreases, decreasing its speed
d. objects in motion decelerate over distance

Gravity, in fact, causes acceleration making choice A incorrect, Unless air resistance counteracts that acceleration, which it may easily do for an object as small and lightweight as a raindrop. Raindrops may lose mass, but that would not decrease their acceleration. Choice D violates Newton's first law of motion

So here the answer is "b"

23. Which vehicle has the greatest momentum?

29. Which is a major difference between eukaryotic and prokaryotic cells?

a. eukaryotic have DNA and prokaryotic have RNA

b. Eukaryotes are animal cells, and prokaryotes are plant cells

c. Eukaryotes have nuclei and prokaryotes do not

d. eukaryotes house ribosomes and prokaryotes have no ribosomes

A good way to remember this is to know that karyose, meaning "kernel" is used to refer to the nucleus of a cell. Pro- means before, and eu- means true. So eukaryotes have a true nucleus and prokaryotes are supposedly an earlier form of cells, ones with no nucleus.

So here the answer is option "c"

30. One difference between DNA and RNA is that:

a. in RNA, adenine bonds with uracil
b. in RNA, guanine is replaced by adenine
c. DNA has three bases, whereas RNA has four
d. DNA lacks the hydrogen bonds found in RNA

As the DNA molecule is translated into RNA, the pairing of bases changes. Adenine no longer pairs with thymine, but rather with uracil

So here the answer is "a"

31. Which of the following steps follows hypothesis development in the scientific process?

a. problem identification
b. question formulation
c. data collection
d. revision and review
