NEW QUESTION # 33
What are the inherited factors transmitted in an organism from generation to generation called?
- A. Genotype
- B. Phenotype
- C. Heterozygote
- D. Homozygote
Answer: A
Explanation:
Inherited factors that are passed from parents to offspring are known as an organism's genotype. The genotype refers to the genetic makeup of an organism, including the specific alleles inherited for each trait.
Heterozygote and homozygote describe specific combinations of alleles but do not refer to inherited factors as a whole. Phenotype refers to the observable traits of an organism, which result from the interaction between genotype and environment. The NEX Science exam often tests the distinction between genotype and phenotype, emphasizing that genotype represents the genetic instructions while phenotype represents the physical expression of those instructions.

NEW QUESTION # 34
A symbiotic relationship where one organism benefits and the other is neither helped nor harmed is referred to as
- A. mutualism.
- B. commensalism.
- C. predation.
- D. parasitism.
Answer: B
Explanation:
Commensalism is a type of symbiotic relationship in which one organism benefits while the other is unaffected. An example is barnacles attaching to whales, where the barnacles gain transportation and access to food, while the whale is neither helped nor harmed. Mutualism benefits both organisms, parasitism benefits one while harming the other, and predation involves one organism killing another for food. Understanding ecological relationships is a key topic on the NEX Science exam, and recognizing the differences between types of symbiosis is essential.

NEW QUESTION # 35
A recipe for pancakes serves 4 people and requires 1.5 cups of flour.
If the cook wants to make enough pancakes to serve 8 people, how much flour is needed?
- A. 1.5 cups
- B. 3 cups
- C. 8 cups
- D. 5.5 cups
Answer: B
Explanation:
This is a proportional reasoning problem. If 4 people require 1.5 cups of flour, then doubling the number of people to 8 means doubling the amount of flour. Multiply 1.5 by 2:
1.5 × 2 = 3 cups.
Therefore, option D is correct. Option A is the original amount, not scaled. Option B greatly overestimates the amount. Option C results from incorrect multiplication. The NEX frequently includes scaling problems related to recipes, dosages, and supplies, so identifying when to multiply or divide is essential.

NEW QUESTION # 36
Reading Comprehension
Passage:
Stress can affect both physical and mental health. Short-term stress may improve alertness, but chronic stress can weaken the immune system, increase blood pressure, and contribute to anxiety and depression.
Which effect of long-term stress is mentioned in the passage?
- A. Improved concentration
- B. Stronger immune response
- C. Increased blood pressure
- D. Faster healing
Answer: C
Explanation:
The passage distinguishes between short-term and chronic stress. While short-term stress may increase alertness, chronic stress is associated with negative health effects. One of the effects specifically mentioned is increased blood pressure. Option C is therefore correct. Options A and D describe benefits not associated with chronic stress in the passage. Option B is incorrect because the passage states that chronic stress weakens, rather than strengthens, the immune system. The NEX exam often includes questions that test the ability to identify contrasting ideas within a passage, such as short-term versus long-term effects.

Which strategy is mentioned as a way to improve time management?
- A. Working without schedules
- B. Avoiding deadlines
- C. Studying without breaks
- D. Prioritizing tasks
Answer: D
Explanation:
The passage discusses several strategies that help improve time management, including creating schedules, prioritizing tasks, and setting realistic goals. Option B directly reflects one of these strategies. The other options contradict or ignore the recommendations in the passage. Avoiding deadlines and working without schedules would worsen time management, and studying without breaks is not mentioned. On the NEX exam, reading comprehension questions often focus on identifying practical strategies or recommendations explicitly stated in the passage. Selecting prioritizing tasks demonstrates accurate understanding of the author's suggestions.

NEW QUESTION # 39
Review the scatter plot of hours students studied for a test and their results.
What can you conclude from the graph?
- A. As hours studied increase, test scores tend to decrease.
- B. Test scores are higher when no hours are spent studying.
- C. As hours studied increase, test scores tend to increase.
- D. There is no relationship between hours studied and test scores.
Answer: C
Explanation:
This question tests interpretation of scatter plots and correlation. In the graph, the horizontal axis represents hours studied, and the vertical axis represents test scores. As the points move from left to right (indicating more hours studied), the points also tend to move upward (indicating higher test scores). This shows a positive relationship between the two variables. While not every point follows a perfect line, the overall trend clearly indicates that students who studied more hours generally achieved higher test scores. Option B correctly describes this positive correlation. Option A is incorrect because scores are not highest when no studying occurs. Option C is incorrect because there is a visible relationship. Option D describes a negative relationship, which is not shown. On the NEX exam, scatter plots are often used to test understanding of trends rather than exact values, so identifying the overall direction of the data is key.

The word"stable"most nearly means:
- A. Fragile
- B. Steady
- C. Changing
- D. Unpredictable
Answer: B
Explanation:
Stable describes something that is steady, consistent, or not changing. Option C best reflects this meaning.
NEX exams frequently use stability-related vocabulary in clinical scenarios.
NEW QUESTION # 41
A nutritionist recommends that a certain client getof his calories from fats,of his calories from proteins, and the remainder of his calories from carbohydrates.
What fraction of all calories should the client get from carbohydrates?
- A. 1/5
- B. 13/20
- C. 2/4
- D. 7/20
Answer: D
Explanation:
This problem tests fraction addition and subtraction within a real-world nutrition scenario, which is typical of the NEX Math Section. First, recognize that all calorie fractions must total 1 (or the whole). The client getsfrom fats andfrom proteins. To combine these fractions, find a common denominator. The least common denominator of 5 and 4 is 20. Convert the fractions:and. Add them together:. This represents the portion of calories from fats and proteins combined. To find the remainder from carbohydrates, subtract from 1:
Therefore, the correct answer is B. This type of problem reinforces careful fraction operations and understanding of "remainder" language on the NEX exam.

NEW QUESTION # 42
Five-eighths of a yard is the same as what percent of a yard?
- A. 37.5%
- B. 40%
- C. 62.5%
- D. 22.5%
Answer: C
Explanation:
This question assesses fraction-to-percent conversion. Start by converting the fractionto a decimal. Divide 5 by 8:
5 ÷ 8 = 0.625.
To convert a decimal to a percent, multiply by 100:
0.625 × 100 = 62.5%.
Therefore, the correct answer is C. The other options represent incorrect conversions: 37.5% equals, 22.5% is not a standard eighth fraction, and 40% equals. On the NEX exam, knowing common fraction-percent equivalents (such as 1/8 = 12.5%) can significantly reduce calculation time and improve accuracy.

NEW QUESTION # 43
The graph below shows the growth projections of four infants during their first year of life.
Based on these projections, how many weeks will it take for all infants to reach at least 30 pounds?
- A. 22 weeks
- B. 25 weeks
- C. 42 weeks
- D. 35 weeks
Answer: B
Explanation:
This question tests interpretation of a line graph, a common NEX skill. To answer, focus on the infant whose weight increases the slowest, becauseallinfants must reach at least 30 pounds. By examining the graph, Infant A has the lowest growth curve and reaches 30 pounds later than the others. Tracing horizontally from 30 pounds to Infant A's line and then down to the x-axis shows that this occurs at approximately 25 weeks.
Although some infants reach 30 pounds earlier, the question asks whenallinfants reach that weight, which is determined by the slowest-growing infant. Therefore, option D is correct. The NEX often includes graph- based questions that require identifying minimums or maximums across multiple data sets, so it is important to carefully read qualifiers like "all," "at least," or "no more than."

NEW QUESTION # 44
In which biochemical family do starch and glycogen belong?
- A. Proteins
- B. Nucleic acids
- C. Lipids
- D. Carbohydrates
Answer: D
Explanation:
Starch and glycogen are both polysaccharides, which are complex carbohydrates composed of many glucose units. Starch is the primary storage form of glucose in plants, while glycogen is the storage form of glucose in animals, particularly in the liver and muscles. Carbohydrates serve as a major energy source for cells. Nucleic acids store genetic information, proteins perform structural and enzymatic functions, and lipids are involved in energy storage and membrane structure. The NEX Science exam often tests classification of biomolecules and their functions, making carbohydrates the correct answer.

NEW QUESTION # 46
You are staining bacterial samples for identification and viewing them under a microscope.
Which bacterial shape do you observe in the sample?
- A. Vibrios
- B. Spirochetes
- C. Cocci
- D. Bacilli
Answer: D
Explanation:
This question tests knowledge of bacterial morphology, which is commonly assessed on the NEX Science exam. Bacteria are often classified based on their shape, which helps in identification and diagnosis. The image shows elongated, rod-shaped bacteria. This shape is characteristic ofbacilli. Bacilli are cylindrical or rod-like and are commonly found in many bacterial species, includingEscherichia coliandBacillus anthracis.
Cocci are spherical in shape, spirochetes are long and spiral-shaped, and vibrios have a curved, comma-like appearance. None of these shapes match the straight rod-like structures shown in the image. Identifying bacterial shape is an important first step in microbiology before further tests such as Gram staining or biochemical analysis are performed. The NEX exam frequently uses images or descriptions to assess whether students can correctly distinguish between cocci, bacilli, spirilla/spirochetes, and vibrios based on visual characteristics. Recognizing bacilli as rod-shaped bacteria is a key foundational concept.
NEW QUESTION # 47
When you increase the angle between your radius and humerus, the action is known as
- A. circumduction
- B. flexion
- C. retraction
- D. extension
Answer: D
Explanation:
Extension is the movement that increases the angle between two bones at a joint. When the arm straightens at the elbow, the angle between the radius and the humerus increases, which is extension. Flexion decreases the angle between bones, circumduction is a circular movement, and retraction refers to pulling a structure backward. Understanding anatomical movement terms is essential for the NEX Science exam, especially in questions related to joints and motion.

NEW QUESTION # 48
Reading Comprehension
Passage:
Sleep plays a critical role in memory consolidation. During certain stages of sleep, the brain processes and stores information learned throughout the day. Lack of sleep has been linked to impaired judgment, slower reaction times, and decreased academic performance.
Which conclusion is best supported by the passage?
- A. People can function normally without sleep
- B. Memory formation is affected by sleep
- C. Academic success depends solely on sleep duration
- D. Sleep is only important for physical health
Answer: B
Explanation:
The correct answer must be directly supported by the information in the passage. The passage clearly explains that sleep helps the brain process and store information, which is essential for memory consolidation. It also states that lack of sleep negatively affects cognitive abilities such as judgment and reaction time. Therefore, the conclusion that memory formation is affected by sleep is well supported. Option A is incorrect because the passage emphasizes mental and cognitive effects, not just physical health. Option C is directly contradicted by the passage's mention of impaired functioning due to lack of sleep. Option D exaggerates the information; while sleep affects academic performance, the passage does not claim it is the sole factor. On the NEX exam, supported-conclusion questions require selecting an answer that is neither too extreme nor unsupported by the passage.

NEW QUESTION # 50
A financial counselor is reviewing the annual tax refunds received by a group of clients. The refunds are shown below:
$500, $857, $1,500, $500, $6,753, $2,500, $3,000
What is the median tax refund?
- A. $1,500
- B. $500
- C. $1,665
- D. $2,230
Answer: A
Explanation:
This question assesses understanding of the median, which is the middle value when data are ordered from least to greatest. First, list the refunds in ascending order:
$500, $500, $857, $1,500, $2,500, $3,000, $6,753.
There are seven values total, so the median is the fourth value in the ordered list. The fourth value is $1,500.
Therefore, option D is correct. Option B represents the mode (most frequent value), not the median. Options A and C are averages or midpoints that do not correspond to the true median position. On the NEX exam, students are frequently tested on distinguishing mean, median, and mode, so remembering that the median is strictly positional-not calculated-is essential.

NEW QUESTION # 51
Which action is an example of inequity in healthcare?
- A. Filtering water for one segment of the community, but not another
- B. Distributing free school lunches to all students
- C. Providing flexible or extended healthcare appointment times
- D. Administering medication to all patients who report pain
Answer: A
Explanation:
Healthcare inequity occurs when certain groups receive fewer resources or lower-quality care than others.
Filtering water for only one segment of a community creates unequal access to a basic health necessity, increasing health risks for those excluded. The other options promote fairness and equal access to care. The NEX Science exam often evaluates understanding of social determinants of health and ethical principles, making option C the clearest example of inequity.

Passage:
Vaccination programs rely on widespread participation to be effective. When a large portion of the population is vaccinated, herd immunity helps protect individuals who cannot be vaccinated.
What is the primary benefit of herd immunity?
- A. It reduces vaccine side effects
- B. It replaces personal hygiene
- C. It eliminates all diseases
- D. It protects unvaccinated individuals
Answer: D
Explanation:
The passage explains that herd immunity occurs when a large percentage of the population is vaccinated, which helps protect those who cannot receive vaccines. Option B correctly states this benefit. The passage does not suggest that herd immunity eliminates all diseases or replaces hygiene practices. It also does not mention reducing side effects. On the NEX exam, cause-and-effect questions require identifying the specific outcome discussed rather than making broad assumptions. Herd immunity's protective effect on vulnerable individuals is the key idea.

NEW QUESTION # 54
Which of the following routes of transmission is most responsible for the spread of hepatitis C from one individual to another?
- A. Sharing needles
- B. Coughing
- C. Sharing a drink
- D. Touching skin
Answer: A
Explanation:
Hepatitis C is a bloodborne virus that is most commonly transmitted through direct blood-to-blood contact.
Sharing needles allows contaminated blood to enter another person's bloodstream, making it the primary mode of transmission. Hepatitis C is not spread through casual contact such as touching skin, coughing, or sharing drinks. Understanding transmission routes is essential for infection prevention and public health, and the NEX Science exam frequently emphasizes distinguishing between airborne, contact, and bloodborne diseases. Because hepatitis C spreads primarily through shared needles, option D is correct.

NEW QUESTION # 55
A healthcare provider recommends that a patient take 200 milligrams (mg) of a pain reliever every 4 hours.
How many grams of the pain reliever should the patient have taken after 8 hours if the recommendation was followed?
(Given 1,000 mg = 1 gram.)
- A. 0.2 grams
- B. 0.4 grams
- C. 40 grams
- D. 20 grams
Answer: B
Explanation:
This is a medication dosage problem, a critical area on the NEX exam. First determine how many doses are taken in 8 hours. Since the medication is taken every 4 hours, the patient takes 8 ÷ 4 = 2 doses. Each dose is
200 mg, so the total amount taken is 200 × 2 = 400 mg. Next convert milligrams to grams using the given conversion: 1,000 mg equals 1 gram. Divide 400 ÷ 1,000 = 0.4 grams. Therefore, the correct answer is D.
Option B represents only one dose. Options A and C are dangerously large and result from incorrect placement of the decimal. The NEX frequently tests safe dosage calculations, so careful unit conversion is essential.
NEW QUESTION # 56
Word Knowledge
The word"maintain"most nearly means:
- A. Reduce
- B. Preserve
- C. Improve
- D. Replace
Answer: B
Explanation:
To maintain something means to keep it at the same level or preserve it. Option C is correct. Understanding everyday academic vocabulary is critical for the NEX verbal section.
