NEW QUESTION # 138
Reading Comprehension
Passage:
Balanced nutrition includes consuming a variety of foods to obtain essential vitamins and minerals. Diets lacking in key nutrients can lead to deficiencies, fatigue, and impaired body function.
What is the main purpose of the passage?
Answer: A
Explanation:
The passage focuses on the importance of balanced nutrition and the need to consume a variety of foods to maintain health. It warns that diets lacking essential nutrients can cause health problems. Option B accurately summarizes the purpose of the passage. Option A is incorrect because supplements are not discussed. Option C is unrelated, and option D contradicts the message of balance. On the NEX exam, purpose questions require identifying the author's intent rather than focusing on minor details.

NEW QUESTION # 139
According to the Centers for Disease Control and Prevention (CDC), approximately 7% of children and adolescents ages 6 to 19 in the United States have a high total cholesterol. If 120,000 children and adolescents in that age range were sampled, approximately how many of them would have a normal total cholesterol?
Answer: A
Explanation:
This is a percentage complement problem. If 7% of children have high cholesterol, then the remaining percentage with normal cholesterol is 100% # 7% = 93%. Convert 93% to a decimal by moving the decimal point two places to the left: 0.93. Multiply this decimal by the total number of children sampled: 0.93 ×
120,000 = 111,600. Therefore, approximately 111,600 children would have normal cholesterol levels, making option D correct. Option A incorrectly calculates 7% instead of the complement. Option C represents 70%, not 93%. Option B is close but incorrect due to rounding. NEX math questions often assess whether students understand that "normal" refers to the remainder after subtracting the affected group.
NEW QUESTION # 140
* Infant A was born premature and weighed 5 pounds at birth.
* Infant B was full term and weighed 11 pounds at birth.
If Infant A gains 4 lb every week and Infant B gains 2 lb every week, how many weeks will it take until they are the same weight?
Answer: C
Explanation:
This is a linear growth problem involving rates. Let t represent the number of weeks. Infant A's weight is represented by 5 + 4t, and Infant B's weight is represented by 11 + 2t. Set the expressions equal to find when their weights match:
5 + 4t = 11 + 2t.
Subtract 2t from both sides:
5 + 2t = 11.
Subtract 5 from both sides:
2t = 6.
Divide by 2:
t = 3 weeks.
Therefore, option C is correct. NEX word problems often involve setting up equations from real-life healthcare scenarios, so identifying starting values and growth rates is essential.

NEW QUESTION # 141
What stimulates gustatory (taste) cells?
Answer: C
Explanation:
Gustatory cells are sensory receptors responsible for taste and are located primarily in taste buds on the tongue. These cells are stimulated by chemical substances that are dissolved in saliva. When food dissolves in saliva, the dissolved molecules bind to receptors on gustatory cells, triggering nerve impulses that are interpreted by the brain as taste. Movement of otoliths is related to balance in the inner ear, deep pressure changes stimulate mechanoreceptors, and photons of light stimulate photoreceptors in the eye. The NEX Science exam frequently tests sensory physiology by asking students to match receptors with the correct type of stimulus. Recognizing that taste is a chemical sense dependent on substances in solution is fundamental.

NEW QUESTION # 142
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.
