NEW QUESTION # 98
You are designing a new community public health program to reduce the incidence of cardiovascular diseases (CVD) in your county.
Which of the following programs would likely result in the best overall outcome?
Answer: D
Explanation:
Combining disease prevention and health promotion provides the greatest overall impact on reducing cardiovascular disease. Prevention identifies and manages risk factors early, while health promotion encourages long-term lifestyle changes such as healthy eating, exercise, and stress reduction. Education alone increases awareness but may not change behavior. Screening without lifestyle intervention has limited long- term effectiveness. The NEX Science exam emphasizes population health strategies, making integrated prevention and promotion the most effective approach.

NEW QUESTION # 99
Review the diagram below showing several stages in the human reproductive cycle.
In which of these structures does the process represented by stage A normally occur?
Answer: C
Explanation:
Stage A in the diagram represents fertilization, where a sperm cell fuses with an egg to form a zygote. In humans, fertilization normally occurs in the fallopian tube, not in the uterus or vagina. After fertilization, the zygote undergoes cell division as it travels toward the uterus for implantation. The ovary produces and releases the egg but is not the site of fertilization. The NEX Science exam commonly tests understanding of reproductive anatomy and sequence of events in human development. Correctly identifying the fallopian tube as the site of fertilization is essential for understanding pregnancy, contraception, and reproductive health.
NEW QUESTION # 100
Veins throughout the body contain structures, indicated by arrows, in the image below.
The structures shown in the image prevent which of the following from occurring?
Answer: B
Explanation:
This question focuses on cardiovascular anatomy and physiology. Veins contain one-way valves that are especially important in the limbs, where blood must travel against gravity to return to the heart. These valves open to allow blood to move toward the heart and close to prevent blood from flowing backward. The structures indicated by the arrows in the image represent venous valves. Without these valves, blood could pool in the veins, leading to conditions such as varicose veins. Forward flow of blood is promoted, not prevented, by these valves. They do not obstruct blood flow under normal conditions, nor do they prevent blood from leaking into tissues-that function is related to capillary structure. The NEX Science exam frequently tests the functional significance of anatomical structures, and recognizing that venous valves prevent backflow of blood is a key cardiovascular concept.
NEW QUESTION # 101
Review the image of the human digestive tract shown below.
What is the principal process occurring in the region labeled 4?
Answer: D
Explanation:
Region 4 in the diagram corresponds to the large intestine. The primary function of the large intestine is the absorption of water and electrolytes from undigested food material. This process helps concentrate waste material into feces before elimination. Assimilation of fatty acids and synthesis of triglycerides occur primarily in the small intestine, especially within intestinal epithelial cells. Hydrolysis of proteins occurs mainly in the stomach and small intestine through the action of enzymes such as pepsin and proteases. The NEX Science exam often tests digestive system function by matching specific organs to their primary processes. Since water absorption is the defining function of the large intestine, option B is correct.

NEW QUESTION # 102
When you increase the angle between your radius and humerus, the action is known as
Answer: C
Explanation:
Extension is the movement that increases the angle between two bones at a joint. When the arm straightens at the elbow, the angle between the radius and the humerus increases, which is extension. Flexion decreases the angle between bones, circumduction is a circular movement, and retraction refers to pulling a structure backward. Understanding anatomical movement terms is essential for the NEX Science exam, especially in questions related to joints and motion.
