NEW QUESTION # 125
Reading Comprehension
Passage:
Health literacy refers to a person's ability to understand health information and make informed decisions.
Individuals with limited health literacy may have difficulty following medical instructions or managing chronic conditions.
What is the primary focus of the passage?
Answer: A
Explanation:
The passage defines health literacy and explains why it is important for managing health and following medical instructions. Option B best captures the main focus. The other options address topics not discussed.
On the NEX exam, purpose questions often begin with a definition followed by explanation, signaling that the passage is meant to inform rather than persuade or compare.

NEW QUESTION # 126
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 # 127
What are the inherited factors transmitted in an organism from generation to generation called?
Answer: C
Explanation:
Inherited factors that are passed from parents to offspring are known as an organism's genotype. The genotype refers to the genetic makeup of an organism, including the specific alleles inherited for each trait.
Heterozygote and homozygote describe specific combinations of alleles but do not refer to inherited factors as a whole. Phenotype refers to the observable traits of an organism, which result from the interaction between genotype and environment. The NEX Science exam often tests the distinction between genotype and phenotype, emphasizing that genotype represents the genetic instructions while phenotype represents the physical expression of those instructions.

NEW QUESTION # 128
Which organ system can alter the amount of CO# in the blood?
Answer: B
Explanation:
The respiratory system directly regulates the level of carbon dioxide (CO#) in the blood. CO# is a waste product of cellular respiration and is removed from the body through exhalation. When breathing rate increases, more CO# is expelled, lowering blood CO# levels. When breathing slows, CO# levels rise. While the cardiovascular system transports CO#, it does not regulate its concentration. The urinary system regulates pH and fluid balance but does not directly remove CO#. The endocrine system controls hormones, not gas exchange. The NEX Science exam frequently emphasizes the role of the respiratory system in maintaining acid-base balance through CO# regulation.
NEW QUESTION # 129
The four main types of macromolecules found in our cells are lipids, carbohydrates, proteins, and
Answer: C
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.
