NEW QUESTION # 43

NEW QUESTION # 44
What is the correct order of blood flow through the cardiovascular system?
Answer: D
Explanation:
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.

NEW QUESTION # 45
Review the diagram below of the human eye.
Structure number 1 is necessary in order for the eye to
Answer: D
Explanation:
Structure number 1 in the diagram represents the lens of the eye. The lens plays a crucial role in focusing incoming light onto the retina so that clear images can be formed. It changes shape through a process called accommodation, allowing the eye to focus on objects at varying distances. Protection from debris is mainly the function of the cornea, eyelids, and eyelashes. Regulation of light entering the eye is controlled by the iris, which adjusts the size of the pupil. Picking up light stimuli is the role of rods and cones located in the retina.
Because the lens is responsible for bending and focusing light precisely onto the retina, option A is correct.
The NEX Science exam frequently tests the relationship between eye structures and their functions, particularly focusing mechanisms.

NEW QUESTION # 46
Reading Comprehension
Passage:
Time management is an important skill for students in demanding programs. Creating schedules, prioritizing tasks, and setting realistic goals can reduce stress and improve academic performance.
Which strategy is mentioned as a way to improve time management?
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 # 47
Which of the following bones form the ball-and-socket joint of the upper extremity?
Answer: B
Explanation:
The ball-and-socket joint of the upper extremity is the shoulder joint. This joint is formed by the head of the humerus (the ball) fitting into the glenoid cavity of the scapula (the socket). This structure allows for a wide range of motion, including flexion, extension, abduction, adduction, and rotation. The ribs do not participate in this joint, and the clavicle connects the scapula to the sternum but does not form the ball-and-socket articulation. Understanding joint structure and function is important for anatomy questions on the NEX Science exam. The shoulder joint's design allows greater mobility than stability, which explains why shoulder dislocations are relatively common.
