1. Which structure contains the genetic material (DNA) of the cell?

• A. Cytoplasm
• B. Nucleus
• C. Cell wall (only present in plant cells)
• D. Golgi apparatus

Correct answer: B

Rationale: The nucleus is the organelle that contains the genetic material (DNA) of the cell. It acts as the control center of the cell, regulating gene expression and coordinating cellular activities. The cytoplasm is the fluid-filled space within the cell where organelles are suspended, but it does not contain the genetic material. The cell wall is a rigid structure found in plant cells that provides support and protection, but it does not house the DNA. The Golgi apparatus is involved in processing and packaging proteins for secretion, but it does not contain the genetic material of the cell.

2. What is the process of making copies of DNA called?

• A. Transcription
• B. Translation
• C. Replication
• D. DNA repair

Correct answer: C

Rationale: A) Transcription is the process of synthesizing RNA from a DNA template. It involves the creation of mRNA molecules from a DNA template. B) Translation is the process of synthesizing proteins from mRNA. During translation, the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids, forming a protein. C) Replication is the process of making copies of DNA. This process occurs before cell division and ensures that each daughter cell receives an identical copy of the genetic material. D) DNA repair is a cellular mechanism that corrects errors in DNA that arise due to various factors such as exposure to mutagens or mistakes during DNA replication. It is essential for maintaining the integrity of the genetic material.

3. Identify the type of clause in the sentence 'When the clock struck midnight, the magic began.'

• A. Main clause
• B. Subordinate clause
• C. Appositive clause
• D. Noun clause

Correct answer: B

Rationale: The clause 'When the clock struck midnight' is a subordinate clause because it does not express a complete thought on its own and depends on the main clause 'the magic began' to form a complete sentence. Subordinate clauses typically begin with subordinating conjunctions like 'when,' 'if,' 'because,' etc., and serve to provide additional information or context to the main clause. Choice A, 'Main clause,' is incorrect because the highlighted clause is not the primary clause that provides the main idea. Choice C, 'Appositive clause,' is incorrect as an appositive clause renames or explains a noun in the sentence, which is not the case here. Choice D, 'Noun clause,' is incorrect as a noun clause functions as a noun within a sentence, and the highlighted clause does not act as a noun but rather as a dependent clause providing contextual information.

4. According to the theory of evolution by natural selection, which of the following statements is true?

• A. Organisms evolve towards perfection
• B. Traits are acquired through use and disuse
• C. Individuals with favorable traits survive and reproduce more
• D. All of the above

Correct answer: C

Rationale: Rationale: A) Organisms evolve towards perfection - This statement is incorrect. Evolution by natural selection does not suggest that organisms evolve towards perfection. Instead, it emphasizes the adaptation of organisms to their environment over time. B) Traits are acquired through use and disuse - This statement reflects Lamarck's theory of evolution, not Darwin's theory of evolution by natural selection. Lamarck proposed that organisms could acquire traits during their lifetime and pass them on to their offspring, which has been largely discredited. C) Individuals with favorable traits survive and reproduce more - This statement accurately reflects the central concept of Darwin's theory of evolution by natural selection. Individuals with traits that are advantageous in their environment are more likely to survive and reproduce, passing on those traits to future generations. D) All of the above - This option is incorrect because not all of the statements are true. Only option C accurately represents the theory of evolution by natural selection.

5. Based on the information provided, what is the most logical reason for this?

• A. There are more addresses ending with these numbers than with the other numbers.
• B. All residences and businesses have addresses ending in these numbers, and they consume the most water.
• C. The residents at these addresses are the most likely to consume more water.
• D. The city is more concerned about water usage in the latter part of the week.

Correct answer: D

Rationale: The town of Audley has implemented a water conservation plan with specific watering schedules based on addresses. The city has designated different days for watering based on the ending digits of addresses, suggesting a concern for regulating water usage throughout the week. Choosing option D as the correct answer aligns with the logical reason behind the designated watering schedule. Option A is incorrect as the distribution of addresses ending with specific numbers is not the central reason for the watering schedule. Option B is incorrect as it generalizes that all addresses ending in specific numbers consume the most water, which is not supported by the provided information. Option C is incorrect as it assumes that residents at specific addresses are the most likely to consume more water, which is not explicitly stated in the given extract.
