Biology

1. What is the difference between a prokaryotic cell and a eukaryotic cell?

Correct answer: B

Rationale: Rationale: - Prokaryotic cells are simpler and do not have a true nucleus. Their genetic material is located in the nucleoid region, which is not enclosed by a membrane. - Eukaryotic cells are more complex and have a true nucleus that houses the genetic material, enclosed within a nuclear membrane. - Both prokaryotic and eukaryotic cells have organelles, but eukaryotic cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, while prokaryotic cells lack these membrane-bound organelles.

2. What is the functional group present in esters?

Correct answer: C

Rationale: Esters have the functional group -COO-, representing a carbonyl group bonded to an oxygen atom. The other choices are associated with different functional groups.

3. Which sentence uses the correlative conjunction "either/or" correctly?

Correct answer: A

Rationale: Option Aa uses "either/or" to present two exclusive options.

4. Which verb tense is most appropriate for this sentence: "By next week, _____ finished the project."

Correct answer: B

Rationale: Option B expresses a future event completed before another future point in time (next week).

5. Neurons, the functional units of the nervous system, belong to which tissue type?

Correct answer: D

Rationale: The correct answer is D: Nervous tissue. Neurons are specialized cells that transmit nerve impulses and are the primary components of the nervous system. Nervous tissue is made up of neurons and supporting cells called neuroglia. Neurons are responsible for processing and transmitting information throughout the body, making them a crucial part of the nervous system. Epithelial tissue (A) is primarily involved in covering and lining surfaces, connective tissue (B) supports and connects other tissues, and muscle tissue (C) is responsible for movement. Therefore, neurons belong to nervous tissue, which is specialized for communication and coordination within the body.

6. Which sentence uses the present perfect continuous tense correctly?

Correct answer: A

Rationale: Option A emphasizes the ongoing action (working) that started in the past and continues to the present.
