Chemistry

1. Which of the following is a characteristic of a solution with a high viscosity?

Correct answer: c

Rationale: Solutions with high viscosity have a high resistance to flow. The other choices do not accurately describe high viscosity.

2. Deuterium, a stable isotope of hydrogen, has a nucleus containing:

Correct answer: B

Rationale: The correct answer is B: 'A proton and a neutron.' Deuterium is an isotope of hydrogen with an atomic number of 1, meaning it has 1 proton in its nucleus. However, deuterium also has a neutron in its nucleus, making it different from regular hydrogen which only has a proton in its nucleus. Therefore, deuterium has a nucleus containing both a proton and a neutron, making option B the correct choice.

3. A garden bed has a side length of 8 meters. What is its perimeter?

Correct answer: C

Rationale: : Since all sides are equal, multiply the side length by 4: perimeter = 4 * side length = 4 * 8m = 32m.

4. Which of the following situations represents work being done on an object?

Correct answer: c

Rationale: Work is done when a force is applied to move an object over a distance.

5. What is the technical term for the involuntary muscular contractions that move food through the digestive tract?

Correct answer: B

Rationale: The correct answer is B: Peristalsis. Peristalsis is the coordinated, rhythmic contraction and relaxation of muscles in the digestive tract that propels food forward. This process helps move food through the esophagus, stomach, and intestines for digestion and absorption of nutrients. Segmentation (option A) is a different process involving alternating contractions in the intestines to mix food with digestive juices. Chylification (option C) is not a recognized term in digestion. Emulsification (option D) is the process of breaking down fats into smaller droplets for easier digestion, typically occurring in the small intestine with the help of bile. Therefore, peristalsis is the specific term for the involuntary muscular contractions responsible for moving food through the digestive tract.

6. The author expresses concern about the...

Correct answer: B

Rationale: The passage's focus on managing the intermittency of renewable energy due to weather conditions implies concern about B.
