English Grammar

1. Which pronoun correctly replaces the underlined phrase in the sentence: "Jessica invited Sarah and me to the party, but I forgot to respond to her."

Correct answer: C

Rationale: "Ours" clarifies that the response forgetting was a joint action by Jessica and the speaker.

2. What is the main function of peroxisomes in the cell?

Correct answer: A

Rationale: Rationale: Peroxisomes are membrane-bound organelles found in eukaryotic cells that contain enzymes involved in various metabolic processes. One of the main functions of peroxisomes is to break down hydrogen peroxide, a toxic byproduct of metabolism, into water and oxygen through the action of the enzyme catalase. This process helps protect the cell from oxidative damage caused by hydrogen peroxide. While peroxisomes are involved in other metabolic functions such as lipid metabolism and the synthesis of bile acids, their primary role is the breakdown of hydrogen peroxide.

3. . Edema, characterized by swelling due to fluid buildup, can be a sign of:

Correct answer: D

Rationale: Edema, which is the accumulation of fluid in tissues leading to swelling, can be caused by various medical conditions. Heart failure can result in fluid retention due to the heart's inability to pump effectively, leading to edema. Liver disease can cause edema by impairing the liver's ability to produce proteins that help maintain fluid balance. Dysfunction of the lymphatic system can also lead to edema, as the lymphatic vessels play a crucial role in draining excess fluid from tissues. Therefore, all the options (heart failure, liver disease, and lymphatic system dysfunction) can contribute to the development of edema, making 'All of the above' the correct answer.

4. Which test is commonly used to assess kidney function?

Correct answer: D

Rationale: The correct answer is D: Creatinine clearance test. This test is commonly used to assess kidney function by measuring how well the kidneys are filtering waste products like creatinine from the blood. Creatinine is a waste product produced by muscles and is normally filtered out by the kidneys. A high level of creatinine in the blood can indicate reduced kidney function. Options A, B, and C are not specifically used to assess kidney function. A complete blood count (CBC) measures different components of the blood like red blood cells, white blood cells, and platelets. A blood sugar test is used to measure glucose levels in the blood. Urinalysis is a test that analyzes the urine for various substances like proteins, glucose, and blood cells, but it is not the primary test for assessing kidney function.

5. What transport mechanism uses vesicles to move materials within the cell?

Correct answer: A

Rationale: The correct answer is A: Endocytosis. Endocytosis is a transport mechanism in which cells take in molecules or particles by engulfing them in a vesicle. This process allows materials to be transported within the cell. Active transport (option B) requires energy to move molecules across the cell membrane against their concentration gradient. Diffusion (option C) is the movement of molecules from an area of high concentration to an area of low concentration. Exocytosis (option D) is the process by which cells release substances from vesicles into the extracellular environment. Therefore, endocytosis is the transport mechanism that uses vesicles to move materials within the cell.

6. What can be inferred about the water management systems in Petra?

Correct answer: C

Rationale: The passage highlights the "elaborate" water systems, suggesting their complexity and importance.
