1. What are apocrine and eccrine?

Correct answer: D

Rationale: Apocrine and eccrine refer to types of sweat glands in the human body. Apocrine sweat glands are larger and located in areas like the armpits and groin, producing a thicker secretion that can be associated with body odor. Eccrine sweat glands are found throughout the skin and are responsible for regulating body temperature through the production of sweat. Understanding the functions and locations of these glands is essential in comprehending the body's thermoregulation processes.

2. The gradual change in a species over time is called:

Correct answer: B

Rationale: - Adaptation refers to the process by which a species becomes better suited to its environment over time. While adaptation is a component of evolution, it specifically refers to the changes that help a species survive and reproduce in its environment. - Speciation is the process by which new species arise from a single ancestral species. It involves the evolution of reproductive isolation between populations. - Natural selection is a mechanism of evolution where individuals with advantageous traits are more likely to survive and reproduce, leading to the increase in frequency of those traits in a population. - Evolution is the gradual change in a species over time, encompassing all the processes such as adaptation, speciation, and natural selection that drive these changes.

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 phenomenon is responsible for the mirage effect seen in deserts?

Correct answer: B

Rationale: Refraction is the bending of light as it passes from one medium to another of different density. In deserts, the temperature gradient causes light to bend, creating the mirage effect where distant objects appear distorted or displaced. Diffraction refers to the bending of light around obstacles or apertures, not the cause of mirages. Interference involves the superposition of two or more waves, which is not the mechanism behind mirages. Polarization refers to the orientation of light waves in a specific plane and is not responsible for the mirage effect in deserts. Therefore, the correct answer is refraction.

5. Which of the following substances is a common base found in household products?

Correct answer: B

Rationale: The correct answer is B, Ammonia (NH₃). Ammonia is commonly found in household products and is used in cleaning agents due to its alkaline properties. Sodium chloride (NaCl) is a common salt and not a base. Vinegar is acetic acid, which is acidic in nature. Lemon juice contains citric acid, making it acidic as well. Therefore, ammonia is the only base among the choices provided.
