Reading

1. Which additional information would be MOST relevant to the topic of the passage?

Correct answer: B

Rationale: Studies on the psychological effects of social media use directly relate to the passage's concerns about mental health impacts, making it the most relevant information.

2. What is the role of RNA in the regulation of gene expression?

Correct answer: B

Rationale: Rationale: A) RNA does not provide energy for the process of gene expression. Energy is typically provided by molecules like ATP. B) RNA plays a crucial role in controlling the timing and location of protein synthesis through processes like transcriptional regulation, RNA splicing, and post-transcriptional modifications. It helps determine when and where specific proteins are produced in the cell. C) While mRNA translates the genetic code into amino acids during the process of translation, this is not the primary role of RNA in the regulation of gene expression. D) RNA does not store genetic information in the same way that DNA does. DNA is the molecule responsible for storing genetic information in the form of genes. Therefore, option B is the most appropriate choice as it accurately describes the role of RNA in regulating gene expression.

3. The phrase "survival of the fittest" refers to:

Correct answer: B

Rationale: Rationale: The phrase "survival of the fittest" is often associated with the concept of natural selection, which was proposed by Charles Darwin. Natural selection is the process by which organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation. This process does not necessarily favor the most complex anatomical structures (option A) or the strongest and most aggressive individuals (option D). Instead, it emphasizes the importance of adaptations that enhance an organism's ability to survive and reproduce in a specific environment. Option C is incorrect because natural selection results in differential reproductive success based on an organism's traits, meaning that not all organisms have an equal probability of survival and reproductive success.

4. Which hormone is responsible for regulating blood sugar levels and is produced by the pancreas?

Correct answer: A

Rationale: The correct answer is A: Insulin. Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. When blood sugar levels rise after a meal, insulin is released to help cells absorb glucose for energy or storage. This process helps to lower blood sugar levels. Glucagon, the hormone mentioned in option B, is also produced by the pancreas but has the opposite effect of raising blood sugar levels when they are too low. Testosterone and estrogen, options C and D, are sex hormones and are not directly involved in regulating blood sugar levels.

5. What is the periodic table?

Correct answer: B

Rationale: The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number, electron configurations, and recurring chemical properties. Elements are arranged in rows (periods) and columns (groups) with similar properties. The elements are listed in order of increasing atomic number, which is the number of protons in the nucleus of an atom. This arrangement reveals a periodic repetition of chemical properties, which is the basis of the periodic law.

6. Which part of the male urinary system is responsible for producing seminal fluid?

Correct answer: C

Rationale: The correct answer is C: Prostate gland. The prostate gland is responsible for producing seminal fluid, which is a milky fluid that nourishes and protects sperm. The bladder stores urine, the urethra is a tube that carries urine from the bladder out of the body, and the kidney filters waste products from the blood to produce urine. The prostate gland, located beneath the bladder, plays a crucial role in male reproductive health by contributing to semen production. Understanding the functions of each part of the male urinary system is important for comprehending reproductive anatomy and physiology.
