1. Which skin condition is characterized by patches of inflamed, reddened skin and is often triggered by allergens or stress?

Correct answer: A

Rationale: Eczema is the correct answer. It presents as patches of inflamed, reddened skin and can be triggered by allergens, stress, or other factors. Psoriasis, on the other hand, is characterized by red, scaly patches rather than inflamed and reddened skin. Acne manifests as pimples and blemishes, not patches of inflamed skin. Vitiligo is characterized by the loss of skin color in patches, which is distinct from the symptoms described in the question.

2. Which of the following is not part of the digestive system?

Correct answer: D

Rationale: The correct answer is 'D: Pancreas.' While the pancreas contributes to digestion by secreting enzymes, it is not part of the main digestive tract. The esophagus, liver, and stomach are integral components of the digestive system. The esophagus helps in the transport of food to the stomach, the stomach aids in food breakdown, the liver produces bile for fat digestion, and the pancreas secretes digestive enzymes. Therefore, the pancreas is the correct answer as it is not part of the primary digestive tract but supports digestion through enzyme secretion.

3. What is the term for the time it takes for a wave to complete one full cycle?

Correct answer: C

Rationale: The period of a wave is the time it takes for one complete cycle to occur. It is the duration between two successive points in the wave that are in the same phase. Frequency, on the other hand, refers to the number of cycles of a wave that occur in a given time period. Amplitude represents the maximum displacement of a wave from its equilibrium position. Wavelength is the distance between two consecutive points on a wave that are in phase. Therefore, the correct answer is 'Period' as it specifically refers to the time taken for a wave to complete one full cycle, distinguishing it from the other choices which represent different properties of a wave.

4. Which type of tissue provides support and structure to the body?

Correct answer: B

Rationale: Connective tissue is the correct answer as it provides support, structure, and strength to the body by holding tissues and organs in place. Muscle tissue is primarily responsible for movement, nervous tissue for communication, and epithelial tissue for covering and lining surfaces. While muscle tissue allows for voluntary and involuntary movement, nervous tissue transmits electrical signals, and epithelial tissue acts as a protective barrier and is involved in absorption and secretion. Therefore, in the context of providing support and structure, connective tissue is the most appropriate choice.

5. Which hormones are responsible for stimulating the development of sex organs and secondary sex characteristics during puberty?

Correct answer: B

Rationale: Testosterone and estrogen are the primary sex hormones responsible for the development of male and female sex organs, respectively, and the emergence of secondary sex characteristics during puberty. Growth hormone, insulin, and thyroid hormone do not directly influence the development of sex organs and secondary sex characteristics during puberty. Growth hormone primarily regulates growth and metabolism, insulin regulates blood sugar levels, and thyroid hormone controls metabolism and energy levels. Therefore, choices A, C, and D are incorrect for this question.
