Correct Answer: D

Rationale: The correct answer is D: Tensile strength. Dense irregular connective tissue, found in tendons and ligaments, is composed of collagen fibers arranged in a random pattern, providing resistance to tension in multiple directions. This structural arrangement allows tendons and ligaments to withstand pulling forces and maintain their shape, ultimately providing tensile strength. Explanation: A: Flexibility - While tendons and ligaments do require some degree of flexibility, their primary function is to provide strength and stability rather than flexibility. B: Lubrication - Lubrication is not a primary function of dense irregular connective tissue in tendons and ligaments. C: Insulation - Dense irregular connective tissue does not primarily serve as an insulating material in tendons and ligaments; its main function is to provide mechanical support and strength. In summary, the correct answer is D because dense irregular connective tissue in tendons and ligaments is specifically designed to provide tensile strength by resisting pulling forces and

Correct Answer: A

Rationale: The correct answer is A: Atom. An atom is the smallest unit of an element that retains its chemical properties. Atoms are composed of protons, neutrons, and electrons. Molecules (B) are made up of two or more atoms bonded together. Compounds (C) are substances composed of two or more different elements chemically bonded. Mixtures (D) are combinations of two or more substances that are physically mixed but not chemically bonded. Therefore, in this context, the correct answer is atom as it specifically refers to the smallest amount of an element that can exist independently with its unique chemical properties.

Correct Answer: B

Rationale: The correct answer is B: Pivot joint. Pivot joints allow rotational movement around a single axis, such as the rotation of the radius around the ulna in the forearm. This type of joint is designed to facilitate the turning or twisting motion. Ball-and-socket joints (A) allow for multi-axial movement, hinge joints (C) enable movement in one direction like a door hinge, and saddle joints (D) have two saddle-shaped surfaces that allow for movement in multiple directions, but not specifically rotational movement around a single axis.
