Chemistry

1. How does the stability of an atom's nucleus influence its radioactive decay?

Correct answer: B

Rationale: Unstable nuclei are more likely to decay through various processes. The stability of an atom's nucleus is a key factor in determining whether it will undergo radioactive decay. Unstable nuclei have an excess of either protons or neutrons, leading to an imbalance in the nucleus. To achieve a more stable configuration, these nuclei will undergo radioactive decay by emitting particles or energy. Stable nuclei, on the other hand, are less likely to undergo radioactive decay as they have a balanced number of protons and neutrons.

2. The passage implies that achieving energy sustainability requires...

Correct answer: B

Rationale: The passage emphasizes the need for both increasing renewable energy and managing its fluctuations, suggesting B as the key to sustainability.

3. What is the name of the microscopic filtering unit within the kidney responsible for waste removal and blood volume regulation?

Correct answer: A

Rationale: The correct answer is A: Nephron. The nephron is the functional unit of the kidney responsible for waste removal and blood volume regulation. It consists of the renal corpuscle, including the glomerulus for filtration, and the renal tubule for reabsorption and secretion. The other options, such as the ureteric bud, renal pyramid, and glomerulus, are structures within the kidney but do not specifically refer to the filtering unit responsible for waste removal and blood volume regulation like the nephron does.

4. During exercise, oxygen is used to convert glucose into energy for muscles. This process is called:

Correct answer: A

Rationale: The correct answer is 'A: Aerobic respiration.' During exercise, muscles require energy to function, and oxygen plays a crucial role in converting glucose into energy through aerobic respiration. This process occurs in the mitochondria of cells and involves the breakdown of glucose to produce ATP, the cell's energy currency. Aerobic respiration is efficient and produces a higher yield of ATP compared to anaerobic respiration or glycolysis alone. Anaerobic respiration (option B) and glycolysis (option C) are also involved in energy production but do not rely on oxygen. Lactic acid fermentation (option D) occurs when there is not enough oxygen available, leading to the accumulation of lactic acid. Therefore, the most appropriate answer is 'A: Aerobic respiration.'

5. The human body's command center, integrating sensory information and coordinating movement and vital functions, is the:

Correct answer: B

Rationale: The correct answer is B: Brain. The brain serves as the command center of the human body, receiving sensory information from various parts of the body and coordinating responses. It is responsible for controlling movement, regulating vital functions such as breathing and heart rate, and processing thoughts and emotions. The lungs (A), kidneys (C), and stomach (D) each have specific functions within the body, but they do not serve as the central command center like the brain does. Therefore, the brain is the correct answer to this question.

6. Scientific findings are constantly evolving. This emphasizes the importance of:

Correct answer: C

Rationale: Science is a dynamic process built on continual questioning and refining of understanding. Openness to new evidence and revision of existing theories is crucial for scientific progress.
