1. Which word best describes the relationship between population growth and smart cities in the passage?

• A. Cause and effect
• B. Analogy
• C. Contrast
• D. Similarity

Correct answer: A

Rationale: The passage identifies rapid population growth as a challenge that smart cities are proposed to address, establishing a causal connection.

2. What is the unit of measurement for power?

• A. Joule (J)
• B. Newton (N)
• C. Watt (W)
• D. Kilogram-meter (kg·m)

Correct answer: c

Rationale: Power is measured in watts (W) in the SI unit system.

3. Which word best describes the relationship between population growth and smart cities in the passage?

• A. Cause and effect
• B. Analogy
• C. Contrast
• D. Similarity

Correct answer: A

Rationale: The passage identifies rapid population growth as a challenge that smart cities are proposed to address, establishing a causal connection.

4. Which statement accurately describes the Linnaean system of classification?

• A. It focuses on evolutionary relationships between organisms
• B. It uses dichotomous keys for identification
• C. It groups organisms based on shared functions
• D. It emphasizes a hierarchical ranking system

Correct answer: D

Rationale: Rationale: The Linnaean system of classification, developed by Carl Linnaeus, is based on a hierarchical ranking system where organisms are grouped into categories based on shared characteristics. This system organizes organisms into a hierarchy of increasingly specific categories, from broad to narrow, such as kingdom, phylum, class, order, family, genus, and species. This hierarchical approach allows for the systematic organization and classification of a wide variety of organisms based on their similarities and differences.

5. Where does bile, a substance that helps digest fats, come from?

• A. Stomach
• B. Pancreas
• C. Liver
• D. Gallbladder

Correct answer: C

Rationale: Rationale: Bile is a substance that helps digest fats by emulsifying them, which means breaking down large fat globules into smaller droplets to increase the efficiency of fat digestion by enzymes. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine to aid in the digestion and absorption of fats. The stomach (option A) is responsible for the initial digestion of food through the action of gastric juices, but bile is not produced in the stomach. The pancreas (option B) secretes digestive enzymes such as lipase to further break down fats in the small intestine, but it does not produce bile. The gallbladder (option D) stores and concentrates bile produced by the liver but does not actually produce bile itself.

6. What is the main factor limiting population growth in K-strategists?

• A. Predation
• B. Availability of resources
• C. Competition
• D. Disease

Correct answer: B

Rationale: Rationale: K-strategists are species that have a low reproductive rate and invest more resources in raising fewer offspring. These species typically inhabit stable environments where resources are limited. The main factor limiting population growth in K-strategists is the availability of resources such as food, shelter, and space. When resources are scarce, K-strategists may struggle to find enough resources to support their population size, leading to decreased reproductive success and population growth. Predation (option A), competition (option C), and disease (option D) can also impact population growth, but the primary limiting factor for K-strategists is the availability of resources.
