NEW QUESTION # 78
What is the term used to describe random changes in DNA, which may be silent, negative, or positive, to the organism in which they occur?

Answer: D

Explanation:
A mutation is a random change in the DNA sequence of an organism. Mutations can occur due to errors during DNA replication, exposure to radiation, or chemical agents. These changes may have no effect (silent mutations), cause harm (negative mutations), or provide an advantage (positive mutations). Recombination refers to the exchange of genetic material during meiosis, not random DNA changes. Duplication involves copying a segment of DNA, and replication is the normal process of copying DNA before cell division. The NEX Science exam often emphasizes that mutations are a source of genetic variation and can influence evolution and disease. Understanding the different possible effects of mutations is essential for topics related to genetics, cancer biology, and inheritance.


NEW QUESTION # 79
Word Knowledge
The word"minimize"most nearly means:

Answer: A

Explanation:
Minimize means to reduce something to the smallest amount possible. Option C is the correct synonym.
Understanding reduction-related vocabulary is important for NEX verbal success.


NEW QUESTION # 80
An acid needs to be diluted at a ratio of 5 grams of acid per 3 liters of water. How many grams of acid are needed for a solution of 24 liters of water to maintain the ratio?

Answer: D

Explanation:
This is a ratio and proportion problem. The given ratio is 5 grams of acid for every 3 liters of water. First determine how many groups of 3 liters are in 24 liters: 24 ÷ 3 = 8. Each group requires 5 grams of acid, so multiply: 8 × 5 = 40 grams. Therefore, option C is correct. Option D results from dividing instead of multiplying. Option B is excessively large and unrealistic. Ratio problems on the NEX require identifying the scaling factor before multiplying.


NEW QUESTION # 81
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.
