Question 1 of 5
Which element is used in jewelry due to its malleability and resistance to tarnish?
Correct Answer: C
Rationale: Gold (C) is the correct answer because it is highly malleable and does not tarnish. Gold is a popular choice for jewelry due to its durability and resistance to corrosion. Iron (A) is not commonly used in jewelry due to its susceptibility to rust. Copper (B) is malleable but prone to tarnishing. Silver (D) is malleable but can tarnish over time, making it less ideal for long-lasting jewelry pieces.
Question 2 of 5
In the body, muscle tissue is involved in which of the following functions?
Correct Answer: D
Rationale: The correct answer is D because muscle tissue is indeed involved in all the functions listed. Muscles generate body heat through metabolism, stabilize joints by providing support and movement, and help maintain posture by keeping the body in an upright position. Therefore, muscle tissue plays a crucial role in all these functions. Choices A, B, and C are incorrect individually as they only represent a part of the functions that muscle tissue is involved in, whereas the correct answer encompasses all aspects of muscle function in the body.
Question 3 of 5
Which organ produces insulin and glucagon?
Correct Answer: D
Rationale: The correct answer is D: Pancreas. The pancreas produces insulin and glucagon, which are hormones involved in regulating blood sugar levels. Insulin helps lower blood sugar levels, while glucagon helps raise them. The salivary glands (A) produce saliva for digestion, the liver (B) plays a role in metabolism and detoxification, and the gallbladder (C) stores and releases bile to aid in digestion. Therefore, the pancreas is the correct organ responsible for producing insulin and glucagon.
Question 4 of 5
Which of the following is responsible for regulating body temperature?
Correct Answer: A
Rationale: The correct answer is A: Hypothalamus. The hypothalamus plays a vital role in regulating body temperature by responding to internal and external temperature changes. It coordinates the body's response to maintain a stable temperature through processes like sweating or shivering. B: Cerebellum is responsible for coordinating movement and balance, not body temperature regulation. C: Pituitary gland regulates hormone production but not directly involved in body temperature regulation. D: Thyroid gland controls metabolism and energy levels but not primarily responsible for regulating body temperature.
Question 5 of 5
Which of the following statements about fungi is FALSE?
Correct Answer: B
Rationale: The correct answer is B because not all fungi are parasitic and harmful to humans. Some fungi are beneficial, while others are neutral. A is correct as fungi can be unicellular or multicellular. C is true as fungi are crucial in breaking down organic matter. D is accurate as some fungi, such as mushrooms, are consumed as food. Overall, choice B is false because it wrongly generalizes all fungi as harmful, which is not the case.
