physics

1. Which term refers to the resistance of a liquid to flow?

Correct answer: B

Rationale: Viscosity is the term that refers to the resistance of a liquid to flow. It is a measure of how thick or sticky a fluid is, and it determines how easily a liquid can flow. Density (A) is a measure of how much mass is contained in a given volume, surface tension (C) is the property of a liquid that allows it to resist an external force due to the cohesive nature of its molecules, and boiling point (D) is the temperature at which a liquid changes to a vapor.

2. Which additional information would be MOST relevant to the topic of the passage?

Correct answer: B

Rationale: Studies on the psychological effects of social media use directly relate to the passage's concerns about mental health impacts, making it the most relevant information.

3. Which of the following is an example of stabilizing selection?

Correct answer: C

Rationale: Rationale: - Stabilizing selection is a type of natural selection that favors the intermediate variants in a population, while selecting against the extreme traits. This results in the maintenance of the current average trait in the population. - Option A is incorrect because stabilizing selection does not favor extreme traits; instead, it favors the average trait. - Option B is incorrect because stabilizing selection does not remove individuals with extreme traits; it acts against extreme traits by favoring the intermediate variants. - Option D is incorrect because stabilizing selection does not favor one specific trait over all others; it favors the average trait by selecting against extreme traits.

4. The study of the geographical distribution of organisms and the factors that influence it is known as:

Correct answer: C

Rationale: Rationale: Biogeography is the study of the geographical distribution of organisms and the factors that influence their distribution patterns. This field of study examines how and why species are distributed where they are, considering factors such as historical events, ecological interactions, and physical geography. Paleontology (option A) is the study of fossils and the history of life on Earth, focusing on extinct organisms. Taxonomy (option B) is the science of classifying and naming organisms based on their characteristics. Population genetics (option D) is the study of genetic variation and evolutionary processes within populations of organisms. In this context, biogeography is the most appropriate choice as it specifically deals with the distribution of organisms in space and time.

5. Which of the following units is equivalent to a joule?

Correct answer: a

Rationale: A joule, as a unit of energy, is equivalent to a newton-meter in terms of work or energy.

6. Which type of nutrient requires the most complex and lengthy digestion process?

Correct answer: B

Rationale: Rationale: Proteins require the most complex and lengthy digestion process among the options provided. When we consume proteins, they need to be broken down into amino acids, which are the building blocks of proteins. This process starts in the stomach with the help of stomach acid and enzymes, continues in the small intestine where more enzymes break down proteins into amino acids, and finally, these amino acids are absorbed into the bloodstream for various bodily functions. Carbohydrates and fats also require digestion, but the process for breaking down proteins into amino acids is more complex and time-consuming. Vitamins, on the other hand, do not require digestion in the same way as proteins, carbohydrates, and fats, as they are already in a form that can be readily absorbed by the body.
