Question 129: If a specific reversible process reached equilibrium, what would happen if more reactants were added?
- The equilibrium would change in favor of the formation of additional products. (Correct answer)
- Nothing, because the reaction has reached equilibrium.
- The reaction would heat up
- The equilibrium position would move, resulting in the formation of more reactants.
Correct answer: The equilibrium would change in favor of the formation of additional products.
This scenario is described by Le Chatelier's Principle, which states that if a change of condition is applied to a system in equilibrium, the system will shift in a direction that relieves the stress. Adding more reactants is a stress, so the equilibrium will shift to consume these reactants. This results in the formation of additional products to re-establish equilibrium.
Question 130: Which of the following is not a property of water?
- Density of liquid form is less than solid form (Correct answer)
- Can absorb/release large quantities of heat without large temperature change.
- High surface tension
- High boiling point compared to other hydrogen compounds
Correct answer: Density of liquid form is less than solid form
The correct answer is that the density of liquid water is *greater* than its solid form (ice), which is an unusual property. Most substances become denser when they solidify. Water's unique hydrogen bonding causes ice to form an open, crystalline structure that is less dense than liquid water, allowing ice to float.

- The enzyme denatured due to pH change (Correct answer)
- The enzyme requires more water
- The substrate was used up
- The solution was too basic
Correct answer: The enzyme denatured due to pH change
Enzymes are highly sensitive to changes in environmental conditions like pH and temperature because these factors can alter their specific three-dimensional structure, particularly the active site. When the pH changes drastically, the enzyme can denature, meaning its shape is altered, rendering it unable to bind to its substrate and function effectively.
Question 161: Which of the following is the closest definition to the word postulate?
- Claim (Correct answer)
- Disagree
- Gather
- Move
Correct answer: Claim
To 'postulate' means to suggest or assume the existence, fact, or truth of something as a basis for reasoning, discussion, or belief.

If a patient is having respiration issues, they are experiencing difficulty with breathing. This can manifest as shortness of breath, wheezing, or other respiratory distress.
Question 186: Divide and simplify: ÷ \/
- 2 2\/8
- 12 2\/3
- 16
- 2 1\/4 (Correct answer)
Correct answer: 2 1\/4
To divide fractions, you multiply the first fraction by the reciprocal of the second fraction. Assuming the fractions are 9/10 and 2/5, the operation becomes 9/10 * 5/2. Multiply the numerators (9*5=45) and the denominators (10*2=20) to get 45/20. Simplifying this improper fraction gives 9/4, which converts to the mixed number 2 1/4.
Question 187: Which conclusion is best supported by the discovery of fossils with similar bone structures in different species?
- They have identical DNA
- They live in the same environment
- They share a common ancestor (Correct answer)

Question 191: A passage states: 'Nosocomial infections affect approximately 1.7 million patients annually in the United States, resulting in 99,000 deaths per year.' Based on this information, which conclusion is most accurate?
- Nosocomial infections are a significant cause of morbidity and mortality (Correct answer)
- Hospitals are unsafe places for patients
- Most hospital patients will develop nosocomial infections
- All nosocomial infections are preventable
Correct answer: Nosocomial infections are a significant cause of morbidity and mortality
The statistics support that nosocomial infections are a significant cause of morbidity (1.7M affected) and mortality (99,000 deaths), without overgeneralizing beyond the data.
Question 192: Each pound has 453.59 grams. 6,577 grams is the weight of a baby. In pounds and ounces, how much does the baby weigh?
- 35 lb 8 oz
- 12 lb 5 oz.
- 14 lb 8 oz. (Correct answer)
- 17 lb 8 oz.
Correct answer: 14 lb 8 oz.
First, convert the baby's weight from grams to pounds by dividing 6,577 grams by 453.59 grams/pound, which yields approximately 14.5 pounds. Next, separate the whole pounds (14 lbs) and convert the remaining decimal (0.5 lbs) into ounces by multiplying by 16 ounces/pound (0.5 * 16 = 8 ounces). Thus, the baby weighs 14 pounds and 8 ounces.

- 2 17\/21 (Correct answer)
- 7 5\/13
- 2 8\/10
- 7 8\/10
Correct answer: 2 17\/21
The question 'Subtract 2/ - 6/' is incomplete, but assuming it refers to a subtraction of mixed numbers that results in 2 17/21, the general process involves finding a common denominator for the fractions, converting mixed numbers to improper fractions if necessary for borrowing, and then subtracting the numerators and whole numbers. For example, if the problem was 6 1/7 - 3 1/3, you would convert to 6 3/21 - 3 7/21, then borrow to get 5 24/21 - 3 7/21, resulting in 2 17/21.
Question 198: Subtract: 3 1 \/ 2 - 2 2\/3
- 5\/16
- 6\/5
- 5\/6 (Correct answer)
- 1 1\/5
Correct answer: 5\/6
To subtract mixed numbers, first convert them into improper fractions. 3 1/2 becomes 7/2 and 2 2/3 becomes 8/3. Find a common denominator, which is 6, so 7/2 becomes 21/6 and 8/3 becomes 16/6. Subtracting these gives 21/6 - 16/6 = 5/6.
Question 199: What is the primary function of transfer RNA (tRNA) during translation?
- Delivering amino acids to the ribosome (Correct answer)

Correct answer: Containing pus
'Purulent' comes from the Latin 'pus,' meaning pus. Purulent drainage is thick, opaque, and often yellow or green, indicating infection at the wound site.
Question 202: What is the meaning of incision?
- Cut (Correct answer)
- Injection
- Closure
- Fracture
Correct answer: Cut
An 'incision' is a surgical cut made in skin or flesh, typically during an operation or medical procedure. It is a precise opening created by a surgeon's instrument. Therefore, 'cut' is the most direct and accurate definition of an incision.
Question 203: Using the Lewis-dot structure model, how many dots would carbon have?
- 2
- 8
- 4 (Correct answer)
- 6
Correct answer: 4
The Lewis-dot structure model represents an atom's valence electrons as dots around its symbol. Carbon is in Group 14 of the periodic table, meaning it has 4 valence electrons. Therefore, carbon would have 4 dots in its Lewis-dot structure.
Question 204: What does it mean to draw an inference?
- Form a conclusion based on information (Correct answer)
- Make a guess with no basis
- Identify the author's name
- Rewrite the text
Correct answer: Form a conclusion based on information
To draw an inference means to form a conclusion or make an educated guess based on the information explicitly provided in the text, combined with one's own prior knowledge and reasoning. It involves 'reading between the lines' to understand implied meanings or consequences that are not directly stated by the author. This skill is crucial for deeper comprehension and critical thinking.
Question 205: How many ounces are in 8 1\/4 pints?
- 2.25 oz
- 132 oz (Correct answer)
- 128 oz
- 136 oz
Correct answer: 132 oz
To convert pints to ounces, you use the standard conversion factor where 1 pint (pt) is equal to 16 ounces (oz). First, convert the mixed number 8 1/4 pints to a decimal or improper fraction (8.25 pints). Then, multiply 8.25 by 16 to find the total number of ounces. This calculation yields 132 ounces.
Question 206: According to the instructions, you must dilute a powder in 3 quarts of water. You only have a container with a liter marking on it. To dilute the powder, how many liters would you use?
- 6.75 liters
- 5 liters
- 2.88 liters (Correct answer)
- 100 liters
Correct answer: 2.88 liters
To convert quarts to liters, use the conversion factor that 1 US liquid quart is approximately 0.946 liters. Therefore, 3 quarts * 0.946 liters/quart equals approximately 2.838 liters. Given the options, 2.88 liters is the closest value, suggesting a slightly different conversion factor (e.g., 1 quart ≈ 0.96 L) or rounding was used.

Question 286: Convert 0.60 to ratio in simplest form
- 2:6
- 1:6
- 3:5 (Correct answer)
- 2:50
Correct answer: 3:5
To convert the decimal 0.60 to a ratio, first express it as a fraction: 60/100. Next, simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 20. This results in 60 ÷ 20 = 3 and 100 ÷ 20 = 5, giving the simplified fraction 3/5, which is written as the ratio 3:5.
Question 287: How far does a runner run (in kilometers) in a 1,000 meter race?
- 0.10 km
- 1\/2 km
- 3 km
- 1 km (Correct answer)
Correct answer: 1 km
To convert meters to kilometers, you need to know that 1 kilometer (km) is equal to 1,000 meters (m). Therefore, to find how many kilometers are in a 1,000-meter race, you divide 1,000 by 1,000. This calculation results in 1 kilometer.
Question 288: During final exams 172 students visited the math lab in total. If 4 out of 11 were male what is the percentage of female students who visited the math lab? (Round to the nearest tenth). a. 63.6%\t
- 63.64%
- 63.6% (Correct answer)
- 62.5%
- 63%
Correct answer: 63.6%
If 4 out of 11 students were male, then the remaining students are female. This means 11 - 4 = 7 out of 11 students were female. To find the percentage of female students, divide the number of female students by the total number of students in the ratio (7/11) and multiply by 100%. This calculation yields approximately 63.636%, which rounds to 63.6% to the nearest tenth.
Question 289: In an exothermic reaction, what happens to energy?
