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 word is spelled correctly?

Correct answer: B

Rationale: Option B is the correct spelling for "to submit or agree without protest."

3. What is the process by which the body maintains a relatively constant blood pH level, even with changes in blood carbon dioxide concentration?

Correct answer: C

Rationale: The correct answer is C: Buffering system. The body maintains a relatively constant blood pH level through the buffering system, which consists of chemical substances that can absorb excess hydrogen ions or release hydrogen ions to adjust pH levels. This system helps prevent drastic changes in blood pH even when there are fluctuations in blood carbon dioxide concentration. Cellular respiration and gas exchange are processes related to obtaining and utilizing oxygen, while deoxygenation refers to the removal of oxygen from a substance. Therefore, the buffering system is specifically responsible for regulating blood pH levels in response to changes in carbon dioxide concentration.

4. A car is accelerating down a hill. Which of the following forces is NOT acting on the car?

Correct answer: B

Rationale: Normal force from the road. The normal force acts perpendicular to the surface of contact and does not contribute to the acceleration down the hill.

5. How does the potential energy of an object change when it is compressed?

Correct answer: b

Rationale: When an object is compressed, it stores potential energy due to its altered position or configuration.

6. Which hormone, produced by the ovaries, is responsible for the development of the uterine lining during the menstrual cycle and supports early pregnancy?

Correct answer: B

Rationale: The correct answer is B: Progesterone. Progesterone is a hormone produced by the ovaries that plays a crucial role in the menstrual cycle and early pregnancy. During the menstrual cycle, progesterone helps to prepare the uterine lining for a potential pregnancy by making it thick and vascularized. If fertilization occurs, progesterone continues to support the early stages of pregnancy by maintaining the uterine lining and preventing menstruation. Estrogen also plays a role in the menstrual cycle by stimulating the growth of the uterine lining, but progesterone is primarily responsible for maintaining the uterine environment suitable for implantation and supporting early pregnancy. Testosterone is a male sex hormone, while prolactin is a hormone involved in milk production after childbirth.
