NEW QUESTION # 139
#3 # 7 =
Answer: C
Explanation:
This problem tests understanding of integer subtraction, especially with negative numbers. On the number line, #3 is already below zero. Subtracting 7 means moving seven more units to the left. Starting at #3 and moving left seven spaces results in #10. Another way to think about this is to rewrite the problem as adding a negative number: #3 # 7 is the same as #3 + (#7). When adding two negative numbers, you add their absolute values and keep the negative sign. The absolute values of #3 and #7 are 3 and 7, and 3 + 7 = 10, so the result is #10. Option A is therefore correct. Option B is a common mistake when students subtract absolute values incorrectly. Options C and D are positive and would only occur if the signs were misunderstood. The NEX Math Section frequently includes integer operations to assess number sense and sign awareness.

NEW QUESTION # 141
Which of the following structures is found only in bacterial cells, not in plant or animal cells?
Answer: B
Explanation:
Bacterial cells are classified as prokaryotic cells, meaning they lack a membrane-bound nucleus. Instead of a nucleus, bacteria contain their genetic material in a region called the nucleoid. The nucleoid is not surrounded by a membrane and is unique to prokaryotic cells. In contrast, plant and animal cells are eukaryotic and store their DNA inside a true nucleus. Cell membranes, ribosomes, and DNA are found in all living cells, including bacteria, plants, and animals. Ribosomes in bacteria are smaller than those in eukaryotic cells, but they serve the same function of protein synthesis. Because the nucleoid region is exclusive to bacteria and other prokaryotes, option C is the correct answer. The NEX Science section frequently tests differences between prokaryotic and eukaryotic cells, making this an important concept to master.

NEW QUESTION # 142
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.)
Answer: C
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.
