1. In which direction do the particles of the medium move in a transverse wave?

Correct answer: A

Rationale: In a transverse wave, the particles of the medium move perpendicular to the direction of wave travel. This means that the particles move up and down or side to side as the wave passes through the medium. This motion creates crests and troughs in the wave, leading to the characteristic oscillation observed in transverse waves. Choice B is incorrect because in transverse waves, the particle movement is not parallel to the direction of wave travel. Choice C is incorrect as the particles do not move in a circular motion in a transverse wave. Choice D is incorrect as the particles do not move opposite to the direction of wave travel; they move perpendicular to it.

2. Which of the following is NOT a type of epithelium?

Correct answer: D

Rationale: The correct answer is D, Pseudostratified columnar. Pseudostratified columnar epithelium is not a type of epithelium. It is a specialized form of simple columnar epithelium. Stratified squamous, simple cuboidal, and stratified columnar are all types of epithelial tissues found in the human body. Stratified squamous epithelium is found in the skin, mouth, and esophagus; simple cuboidal epithelium lines kidney tubules and glands; stratified columnar epithelium is present in parts of the respiratory tract and male urethra.

3. Which of the following is not a type of muscle tissue?

Correct answer: D

Rationale: The correct answer is D, Adipose. Adipose tissue is a type of connective tissue that stores fat, not muscle tissue. Skeletal, smooth, and cardiac are all types of muscle tissues found in the body. Skeletal muscle tissue is responsible for voluntary movements and is attached to bones. Smooth muscle tissue is found in the walls of hollow organs and blood vessels, responsible for involuntary movements. Cardiac muscle tissue is found in the heart and is responsible for pumping blood throughout the body. Adipose tissue, on the other hand, primarily functions as a storage site for energy in the form of fat.

4. Differentiate between the digestive and respiratory systems.

Correct answer: D

Rationale: The correct answer is D - Lungs. The mouth, stomach, and small intestine are all components of the digestive system, which is responsible for breaking down food into nutrients that the body can absorb. On the other hand, the lungs are part of the respiratory system, which facilitates the exchange of oxygen and carbon dioxide between the body and the environment through breathing. While the digestive system processes food for energy and nutrients, the respiratory system is primarily focused on the exchange of gases necessary for cellular respiration. Choices A, B, and C are incorrect as they are all organs associated with the digestive system and do not pertain to the respiratory system.

5. Which property remains constant despite possible changes to the element?

Correct answer: A

Rationale: The correct answer is 'Atomic number' (A). The atomic number of an element remains constant as it defines the number of protons in the nucleus, which does not change despite various chemical reactions or physical processes affecting the element. The number of protons in the nucleus determines the identity of the element, and this fundamental property remains unchanged even if the element undergoes chemical reactions, forms ions, or changes its physical state. Choices B, C, and D are incorrect because the number of electrons (B) can change in chemical reactions, atomic mass (C) can vary with isotopes, and isotopic form (D) refers to variations in the number of neutrons in the nucleus, which can result in different isotopes of an element.
