physics

1. Which property of a wave represents the distance between two successive identical points on a wave?

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

2. Which of the following is a risk factor for developing kidney stones?

Correct answer: C

Rationale: Having a family history of kidney stones is a risk factor for developing them because genetics play a role in kidney stone formation. Individuals with a family history are more likely to inherit genetic factors that increase the likelihood of developing kidney stones. While consuming a diet rich in fruits and vegetables, maintaining adequate hydration with water, and regularly engaging in moderate exercise are generally healthy habits that can help prevent kidney stones, they are not direct risk factors for developing them. Therefore, option C, having a family history of kidney stones, is the correct answer.

3. Which of the following is an example of static friction?

Correct answer: c

Rationale: Static friction occurs when an object is at rest and prevents it from moving when a force is applied.

4. Maintaining good muscle strength and flexibility as we age becomes important to avoid:

Correct answer: B

Rationale: The correct answer is B: 'Falls.' Maintaining good muscle strength and flexibility as we age is crucial for preventing falls, which become more common with age and can lead to serious injuries such as fractures. Strong muscles and good flexibility help in maintaining balance and stability, reducing the risk of falls. Headaches, anxiety, and the common cold are not directly related to muscle strength and flexibility, making them less likely to be avoided by focusing on these aspects of physical health.

5. What is the name of the structure that packages DNA in eukaryotic cells?

Correct answer: A

Rationale: Rationale: - A nucleosome is the basic structural unit of DNA packaging in eukaryotic cells. It consists of DNA wrapped around a core of histone proteins. - Chromatin refers to the complex of DNA and proteins found in the nucleus of a eukaryotic cell, including nucleosomes. - Histones are the proteins around which DNA is wrapped to form nucleosomes. - Centromere is a region of a chromosome where the two sister chromatids are joined and to which spindle fibers attach during cell division.

6. The term "goiter" refers to a condition characterized by:

Correct answer: B

Rationale: The term 'goiter' specifically refers to the abnormal enlargement of the thyroid gland. This can be due to various reasons such as iodine deficiency, Hashimoto's thyroiditis, or Graves' disease. Options A, C, and D are incorrect as they describe conditions related to other glands and hormones in the endocrine system. It is important to differentiate between different endocrine disorders to accurately diagnose and treat patients. Therefore, the correct answer is B, as a goiter is characterized by the excessive growth of the thyroid gland.
