1. An object is thrown at an angle. Which of the following forces acts HORIZONTALLY on the object during its flight?

Correct answer: C

Rationale: During the flight of the object, the only force that acts horizontally on the object is air resistance. Air resistance opposes the motion of the object through the air and acts in the direction opposite to the object's velocity. Gravitational force acts vertically downward, influencing the object's weight and vertical motion. The normal force from the ground acts perpendicular to the ground to support the object's weight. The force of throwing initially imparts velocity to the object at an angle, but it does not act horizontally throughout the flight.

2. Beta waves, associated with alertness and focused attention, typically fall within the range of:

Correct answer: D

Rationale: Beta waves, associated with alertness and focused attention, typically fall within the range of 13-30 Hz. These waves are present when individuals are engaged in cognitive tasks, problem-solving, or focused mental activities. Options A, B, and C are incorrect because these frequency ranges are not characteristic of beta waves. Beta waves are higher in frequency and are associated with more active mental states compared to the ranges mentioned in options A, B, and C. Therefore, the correct answer is 13-30 Hz (Choice D).

3. Which plane divides the body into left and right halves?

Correct answer: A

Rationale: The correct answer is A: Sagittal/Median Plane. This plane divides the body into left and right halves. The Frontal/Coronal Plane (choice B) divides the body into front and back, while the Transverse/Cross-Section Plane (choice C) divides it into top and bottom. The Horizontal Plane (choice D) divides the body into upper and lower portions. Understanding these planes is essential in anatomy as they help describe the orientation and relationships of body structures.

4. What property of matter determines its resistance to changes in shape or size?

Correct answer: A

Rationale: The correct answer is 'Solid.' Solids have a definite shape and volume, providing them with a strong resistance to changes in shape or size. Liquids and gases do not have a definite shape, making them prone to changing shape or size easily. Plasmas, on the other hand, are ionized gases with high energy levels and lack a definite shape or volume, which does not contribute to resistance against changes in shape or size. Therefore, the properties of solids make them best suited for resisting changes in shape or size compared to liquids, gases, and plasmas.

5. The term 'symbiotic relationship' describes an interaction between two organisms where:

Correct answer: D

Rationale: In a symbiotic relationship, both organisms involved benefit from the interaction. This mutually beneficial relationship can take different forms, such as mutualism where both organisms benefit, commensalism where one organism benefits and the other is unaffected, or parasitism where one organism benefits at the expense of the other. In this case, the term 'symbiotic relationship' specifically refers to a scenario where both organisms derive some form of benefit from their interaction. Choices A, B, and C are incorrect because they do not accurately describe a symbiotic relationship. In symbiosis, both organisms benefit, making option D the correct choice.
