Answer: C

NEW QUESTION # 48
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?
Answer: A
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.

NEW QUESTION # 49
Three nurses work a combined total of 130 hours each week. If Nurse A worked 5 days forhours each day, and Nurse B worked 4 days forhours each day, how many hours did Nurse C work?
Answer: C
Explanation:
This is a multi-step word problem involving mixed numbers and total subtraction, commonly seen on the NEX. First calculate Nurse A's total hours:. Multiply by 5 days:hours. Next, calculate Nurse B's total hours:.
Multiply by 4 days:hours. Now add the hours worked by Nurses A and B:
41.25 + 42 = 83.25 hours (or).
Subtract this from the total combined hours:
130 # 83.25 = 46.75 hours.
Convert 0.75 to a fraction:.
So Nurse C workedhours, making option D correct. The NEX often tests accurate step-by-step calculation with workplace scenarios.

NEW QUESTION # 51
The four main types of macromolecules found in our cells are lipids, carbohydrates, proteins, and
Answer: B
Explanation:
Macromolecules are large, complex molecules essential for life. The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates provide energy and structural support, lipids are involved in energy storage and membrane structure, proteins perform a wide range of functions including enzymes and transport, and nucleic acids store and transmit genetic information.
DNA and RNA are examples of nucleic acids. The other answer choices-fatty acids, unsaturated fats, and phospholipids-are all types of lipids rather than separate macromolecule categories. The NEX Science exam often assesses whether students can distinguish between macromolecule categories and their subcomponents.
Recognizing nucleic acids as one of the four major macromolecules is fundamental to understanding genetics, protein synthesis, and cell function.
