1. Which hormone, produced by the pancreas, is released in response to low blood sugar levels and stimulates the release of glucose into the bloodstream?

Correct answer: B

Rationale: Glucagon is the hormone produced by the pancreas that is released in response to low blood sugar levels. It acts to stimulate the release of glucose into the bloodstream by promoting the breakdown of glycogen in the liver. Insulin, conversely, is released in response to high blood sugar levels and promotes the uptake of glucose by cells. Cortisol is a steroid hormone produced by the adrenal glands that regulates metabolism and the immune response. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism but is not involved in responding to low blood sugar levels.

2. What is the product of translation from an RNA template?

Correct answer: C

Rationale: Translation is the process by which the genetic information carried by mRNA is decoded to synthesize a polypeptide chain. This essential process occurs at the ribosomes within the cell. The product of translation from an RNA template is a polypeptide, not DNA, lipid, or carbohydrate. DNA is involved in transcription, lipids are not directly produced in translation, and carbohydrates are not synthesized through translation. Therefore, the correct product resulting from translation from an RNA template is a polypeptide, making choice C, 'Polypeptide,' the correct answer.

3. A researcher wants to conduct qualitative research. Which method should they use?

Correct answer: A

Rationale: Qualitative research focuses on gathering non-numerical, descriptive data to explore experiences, behaviors, or perspectives. Collecting patient narratives aligns with qualitative research as it involves capturing detailed accounts of individuals' experiences or viewpoints. Choices B, C, and D involve more quantitative approaches by focusing on measurable quantities, observations, or structured note-taking, which are not characteristic of qualitative research methods.

4. Water is considered a universal solvent due to its ____.

Correct answer: B

Rationale: The correct answer is B: Adhesion. Water's polarity allows it to dissolve many substances due to its ability to adhere to and interact with other molecules, making it an effective solvent. Cohesion refers to water molecules sticking together, molarity is a measure of concentration, and dilution refers to the process of reducing the concentration of a solute in a solution, none of which directly relate to water's role as a universal solvent.

5. Which hormone, produced by the pancreas, regulates blood sugar levels by promoting the uptake of glucose into cells?

Correct answer: A

Rationale: Insulin is the correct answer. It is produced by the pancreas and plays a crucial role in regulating blood sugar levels by facilitating the absorption of glucose into cells. When blood sugar levels are elevated, insulin is released to help cells utilize glucose for energy or store it for future use. Glucagon, choice B, is produced by the pancreas as well but has the opposite effect of raising blood sugar levels by releasing stored glucose into the bloodstream. Cortisol, choice C, is a hormone produced by the adrenal glands that is involved in the stress response and metabolism, not specifically in regulating blood sugar levels. Thyroxine, choice D, is a hormone produced by the thyroid gland that regulates metabolism but is not directly involved in the uptake of glucose into cells.
