Question 1 of 5

Which of the following are examples of positive correlation?

Correct Answer: D

Rationale: The correct answer is D because a positive correlation indicates that as one variable increases, the other variable also increases. In this case, when plotting rainfall against plant length, if the line trends to the upper right, it shows that as rainfall increases, the plant length also increases. This demonstrates a positive correlation. A is incorrect because it describes a negative correlation where an increase in rainfall leads to a decrease in plant stem length. B is incorrect as it suggests a positive correlation between rainfall and roots length. C is incorrect as a line trending to the lower right also indicates a negative correlation between the variables.

Question 2 of 5

What is the role of the kidneys in the body?

Correct Answer: B

Rationale: The correct answer is B: To filter waste from the blood. The kidneys are responsible for filtering waste products and excess fluids from the bloodstream to form urine. This process helps maintain the body's overall balance of fluids and electrolytes. Regulating body temperature is primarily controlled by the skin and sweat glands, not the kidneys (choice A). While the kidneys do produce hormones like erythropoietin and renin, their primary function is waste filtration, not hormone production (choice C). Transporting oxygen is primarily the role of the respiratory and circulatory systems, not the kidneys (choice D).

Question 3 of 5

Which part of the brain controls breathing and heart rate?

Correct Answer: B

Rationale: The correct answer is B: Medulla oblongata. The medulla oblongata, located in the brainstem, controls essential functions like breathing and heart rate. It contains centers that regulate these automatic processes. The cerebrum (A) is responsible for higher brain functions, not controlling basic physiological functions. The thalamus (C) serves as a relay station for sensory information, not for regulating breathing and heart rate. The cerebellum (D) plays a role in coordination and movement, not in controlling vital functions like breathing and heart rate.

Question 4 of 5

What is the role of bile in digestion?

Correct Answer: B

Rationale: Bile plays a crucial role in digestion by emulsifying fats. It breaks down large fat molecules into smaller droplets, increasing the surface area for enzymes to digest fats. This process aids in the absorption of fat-soluble vitamins and fatty acids. Choices A, C, and D are incorrect as bile does not directly break down carbohydrates, neutralize stomach acid, or absorb proteins in digestion.

Question 5 of 5

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

Correct Answer: A

Rationale: The correct answer is A: Collecting patient narratives. Qualitative research aims to understand individuals' experiences and perceptions in-depth. Collecting patient narratives allows for capturing subjective insights, emotions, and personal perspectives. This method helps uncover themes, patterns, and nuances in participants' stories, providing rich data for analysis. B: Tracking drug dosage and blood levels is quantitative research, focusing on numerical data. C: Observing physical changes is more suitable for quantitative or observational research. D: Writing journal notes about the research experience is reflective and may provide insights but does not capture the essence of qualitative research, which is to explore subjective experiences.
