Biology

1. Organisms that break down dead organisms and return nutrients to the environment are called:

Correct answer: B

Rationale: Rationale: Decomposers are organisms that break down dead organisms and organic matter, such as bacteria, fungi, and some insects. They play a crucial role in the ecosystem by breaking down complex organic materials into simpler forms, releasing nutrients back into the environment for other organisms to use. Producers (option A) are organisms that produce their own food through photosynthesis, consumers (option C) are organisms that consume other organisms for energy, and parasites (option D) are organisms that live on or in another organism and benefit at the host's expense.

2. Based on the information provided, which statement is LEAST likely to be supported by the author?

Correct answer: B

Rationale: While the passage mentions smart grids, its primary focus is on managing the intermittency of renewable energy, making B the least likely statement the author would strongly support.

3. 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.

4. What is the mass number of an element?

Correct answer: B

Rationale: The mass number of an element is the total number of protons and neutrons in the nucleus of an atom. It is represented by the symbol A and is written as a superscript to the element's symbol. For example, the mass number of carbon-12 is 12, which means that a carbon-12 atom has 6 protons and 6 neutrons in its nucleus.

5. What is the author's stance towards the idea of smart cities?

Correct answer: C

Rationale: The passage acknowledges both the promise and challenges of smart cities, demonstrating a balanced perspective.

6. Identify the adjective in the following sentence: The colorful sunset painted the sky with vibrant hues.

Correct answer: C

Rationale: Adjectives modify nouns and pronouns. The adjective "colorful" describes the noun "sunset".
