1. What property of a substance refers to its ability to be drawn into thin wires?

Correct answer: B

Rationale: Ductility is the property of a substance that allows it to be drawn into thin wires without breaking. Conductivity refers to the ability of a substance to conduct electricity or heat, not to be drawn into wires. Viscosity is the measure of a fluid's resistance to flow, not related to the ability to be drawn into wires. Malleability is the property of a substance that allows it to be hammered or rolled into thin sheets, not specifically related to being drawn into wires. Therefore, the correct property for the ability to be drawn into thin wires is ductility.

2. Connective tissue provides support and connects other tissues. What is the main component that gives connective tissue its strength?

Correct answer: A

Rationale: Collagen fibers are the main component that gives connective tissue its strength. Collagen is a fibrous protein that provides structural support and tensile strength to connective tissues, allowing them to withstand stretching and tension. Epithelial cells, nerve cells, and blood cells are not the main components responsible for the strength of connective tissue. Epithelial cells are specialized for covering and lining surfaces, nerve cells transmit signals, and blood cells are involved in various functions like oxygen transport and immune response, but they do not provide the structural strength typical of collagen fibers in connective tissue.

3. What is the pH of a solution with a hydrogen ion concentration of (1x10^{-9}) M?

Correct answer: C

Rationale: The pH of a solution can be calculated using the formula: pH = -log[H+]. Given that the hydrogen ion concentration is \(1 \times 10^{-9}\) M, the pH can be calculated as pH = -log(1 x 10^-9) = 9. Therefore, the correct answer is C) 9.

4. Long bones are one of the five major types of bones in the human body. Which of the following bones are long bones?

Correct answer: D

Rationale: Long bones are characterized by their elongated shape and include bones like the ulna, fibula, and humerus. These bones are crucial for providing support, structure, and facilitating movement in the human body. The sacrum, clavicle, and patella are not classified as long bones. The sacrum is a triangular bone at the base of the spine, the clavicle is a collarbone, and the patella is the kneecap. While these bones have important functions, they do not fit the definition of long bones due to their shape and structure.

5. What is cystitis an inflammation of?

Correct answer: B

Rationale: Cystitis is an inflammation of the bladder. It is typically caused by a bacterial infection and can lead to symptoms such as frequent urination, pain or burning during urination, and lower abdominal discomfort. The inflammation specifically affects the bladder lining. Choices A, C, and D are incorrect. Kidneys are not the site of inflammation in cystitis; they are associated with conditions like pyelonephritis. Ureters are tubes that connect the kidneys to the bladder, and the urethra is the tube that carries urine from the bladder to outside the body. Therefore, the correct answer is 'Bladder.'
