1. What are the three types of muscle tissues?

Correct answer: B

Rationale: The correct answer is B: Skeletal, cardiac, smooth. Skeletal muscle tissue is responsible for voluntary movement, cardiac muscle tissue is found in the heart and is responsible for involuntary heart contractions, and smooth muscle tissue is located in organs and is responsible for involuntary movements. Therefore, the three types of muscle tissues are skeletal, cardiac, and smooth. Choices A, C, and D are incorrect because they include types of tissues that are not classified as muscle tissues. Epithelial and connective tissues are different types of tissues that serve other functions in the body, not related to muscle contractions.

2. How many bones are there in the adult human skeleton?

Correct answer: B

Rationale: The correct answer is B: 206. The adult human skeleton consists of 206 bones. These bones are categorized into the axial skeleton, which includes the skull, vertebral column, and rib cage, and the appendicular skeleton, comprising the bones of the limbs and girdles. Each bone has a specific function in providing structure and support to the body. Choices A, C, and D are incorrect because they do not represent the accurate number of bones in the adult human skeleton. It is essential to remember the correct number of bones in the human skeleton for a better understanding of the skeletal system.

3. What phenomenon occurs when two identical waves are perfectly aligned and reinforce each other?

Correct answer: D

Rationale: Constructive interference occurs when two identical waves are perfectly aligned and reinforce each other. This results in an increase in the overall amplitude of the wave. Refraction refers to the bending of waves as they pass from one medium to another, reflection is the bouncing back of waves when they encounter a boundary, and diffraction is the bending of waves around obstacles and openings. In this scenario, the waves are not changing direction or bending but rather combining to produce a wave with a larger amplitude, which is characteristic of constructive interference.

4. Which of the following is a property of amphiprotic substances?

Correct answer: C

Rationale: The correct answer is C: Can act as both acids and bases. Amphiprotic substances have the ability to donate a proton (act as an acid) or accept a proton (act as a base) depending on the reaction conditions. This dual nature allows them to participate in a wide range of chemical reactions, making them versatile and important in various chemical processes. Choices A and B are incorrect because amphiprotic substances are not limited to reacting with only acids or bases; they can interact with both. Choice D is incorrect because amphiprotic substances are not inert; they actively participate in chemical reactions by donating or accepting protons.

5. What happens when the diaphragm contracts?

Correct answer: B

Rationale: When the diaphragm contracts, it moves downward, creating more space in the chest cavity. This expansion of the chest cavity causes the lungs to expand as well, allowing air to be drawn into the lungs during inhalation. Therefore, the correct answer is that the lungs expand to allow air intake when the diaphragm contracts. Choices A, C, and D are incorrect because when the diaphragm contracts, it does not expel air from the lungs, cause the vocal cords to vibrate, or narrow the trachea to control airflow.
