NEW QUESTION # 143
Which of the following routes of transmission is most responsible for the spread of hepatitis C from one individual to another?
Answer: D
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 # 144
An acid needs to be diluted at a ratio of 5 grams of acid per 3 liters of water. How many grams of acid are needed for a solution of 24 liters of water to maintain the ratio?
Answer: A
Explanation:
This is a ratio and proportion problem. The given ratio is 5 grams of acid for every 3 liters of water. First determine how many groups of 3 liters are in 24 liters: 24 ÷ 3 = 8. Each group requires 5 grams of acid, so multiply: 8 × 5 = 40 grams. Therefore, option C is correct. Option D results from dividing instead of multiplying. Option B is excessively large and unrealistic. Ratio problems on the NEX require identifying the scaling factor before multiplying.
NEW QUESTION # 145
Reading Comprehension
Passage:
Sleep deprivation can impair immune function, making individuals more susceptible to illness. Over time, chronic lack of sleep may increase the risk of serious health conditions.
Which statement is best supported by the passage?
Answer: B
Explanation:
The passage states that lack of sleep weakens immune function and increases susceptibility to illness. This supports the conclusion that adequate sleep supports immune health. Option C accurately reflects this relationship. Options A and D contradict the passage, while option B exaggerates the effect. NEX questions often test the ability to infer logical conclusions without overgeneralizing.

NEW QUESTION # 146
You are staining bacterial samples for identification and viewing them under a microscope.
Which bacterial shape do you observe in the sample?
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 # 147
Reading Comprehension
Passage:
Good nutrition is especially important during childhood because the body is growing rapidly. A diet lacking essential nutrients may result in delayed growth, weakened immunity, and difficulty concentrating in school.
Which consequence of poor nutrition is mentioned in the passage?
Answer: C
Explanation:
The passage explains that childhood nutrition plays a critical role in growth and development. It specifically states that a lack of essential nutrients can lead to delayed growth, weakened immunity, and difficulty concentrating. Option C directly reflects one of the consequences listed in the passage, making it the correct answer. The other options are either the opposite of what is stated or not mentioned at all. NEX reading comprehension questions often test the ability to locate explicit information rather than inferred benefits.
Selecting delayed growth shows careful attention to the details provided in the passage.
