問題 #132
What is the result of crossing over during meiosis?
答案：A
解題說明：
Crossing over is a key event that occurs during prophase I of meiosis. During this process, homologous chromosomes pair up and exchange corresponding segments of DNA. Specifically, non-sister chromatids exchange genetic material, which results in new combinations of alleles. The primary result of this exchange is increased genetic variation in gametes, which is essential for evolution and diversity within a species. While chiasmata are structures formed during crossing over, they describe the physical points of contact rather than the outcome of the process. Lining up at the metaphase plate and random assortment occur later during meiosis and are separate mechanisms of genetic variation. Therefore, the correct result of crossing over is the exchange of DNA segments between homologous chromosomes. This process ensures that offspring have unique genetic combinations that differ from both parents, which is a core concept tested on the NEX Science exam.

問題 #133
What is the correct order of blood flow through the cardiovascular system?
答案：B
解題說明：
Blood flows in a continuous loop through the cardiovascular system. It is pumped from the heart into arteries, which carry oxygenated blood away from the heart. Arteries branch into smaller vessels that lead to capillaries, where gas and nutrient exchange occurs. Blood then flows into veins, which return deoxygenated blood back to the heart. The other options list structures in an incorrect order. Understanding blood flow pathways is a fundamental concept on the NEX Science exam and is essential for interpreting cardiovascular function and disorders.

問題 #134
A rectangle's length and width are 4 centimeters (cm) and 6 cm. What is
1
2
2
1
the area of this rectangle?
(Given Area = length × width.)
答案：C
解題說明：
This problem tests area formulas and fraction application. First calculate the full area of the rectangle using the given formula: Area = length × width. Multiply 4 cm by 6 cm to get 24 cm². The question asks for one- half of the area, not the total area. Divide 24 by 2: 24 ÷ 2 = 12 cm². Therefore, option B is correct. Option C is the full area, not half. Option A results from subtracting instead of dividing. Option D represents an incorrect partial calculation. NEX geometry questions often require careful reading to determine whether the question asks for total area or a fraction of it.
問題 #135
An upcoming event has a total budget of $500.
* Decorations are
1
8

of the budget.
* Food is 25% of the budget.
* The remaining budget is for both the venue and entertainment.
How much money will be available to spend on the venue and entertainment?
答案：C
解題說明：
This problem tests fractions, percentages, and subtraction of parts from a whole-common NEX skills. First calculate the amount spent on decorations:
1
8

1
of $500 equals $62.50. Next calculate the food cost: 25% is equivalent to 0.25, and 0.25 × 500 = $125. Add these two expenses together: $62.50 + $125 = $187.50. This represents the portion of the budget already allocated. To find the remaining budget for venue and entertainment, subtract this amount from the total budget: $500 # $187.50 = $312.50. Therefore, option A is correct. Option B assumes only one category was subtracted. Option C results from incorrect fraction conversion. Option D represents the amount already spent, not the remainder. NEX questions often require careful step-by-step subtraction after converting fractions and percentages correctly.

問題 #136
Twenty daily systolic blood pressure measurements are shown in the graph. The red line indicates when a patient stopped taking their blood pressure medication.
Estimate the patient's average increase in blood pressure from the first set of 10 measurements to the second set of 10 measurements.
答案：C
解題說明：
This problem tests estimation and interpretation of scatter plots. The first 10 measurements (before the red line) cluster around an average of approximately 140 mmHg. The second set of 10 measurements (after the red line) cluster around approximately 170 mmHg. To estimate the increase, subtract the earlier average from the later average: 170 # 140 = 30 points. Therefore, option C is correct. Options A and D represent total values rather than the change between averages. Option B overestimates the difference. On the NEX, estimation questions do not require exact calculations; instead, you must identify reasonable average values from visual data and compare them correctly.
