1. What occurs in each of the three phases of the uterine cycle?

Correct answer: D

Rationale: The correct answer is D. In the proliferative phase of the uterine cycle, the uterine lining thickens in preparation for a possible pregnancy. Ovulation occurs around day 14 of the cycle. The menstrual phase is when the uterine lining sheds if pregnancy has not occurred. Choice A is a duplicate of the correct answer. Choice B is incorrect as ovulation occurs during the mid-cycle, which is the ovulatory phase, not the secretory phase. Choice C is incorrect because the uterine lining sheds during the menstrual phase, not the secretory phase.

2. Which method is most suitable for measuring the volume of a cube?

Correct answer: B

Rationale: The correct answer is B. To measure the volume of a cube, you need to use a mathematical formula that takes into account the dimensions of the cube, specifically the length of its sides. Using a measuring wheel alone or a triple beam balance is not suitable for determining the volume of a cube. A graduated cylinder is used to measure the volume of liquids, not geometric solids like cubes.

3. Who is credited with the discovery of nuclear fission?

Correct answer: C

Rationale: Enrico Fermi is credited with the discovery of nuclear fission. In 1934, Fermi bombarded uranium with neutrons, leading to the splitting of the uranium nucleus and the release of energy. This groundbreaking discovery laid the foundation for the development of nuclear power and weapons. Marie Curie is known for her pioneering research on radioactivity, but she did not discover nuclear fission. Albert Einstein made significant contributions to physics, including the theory of relativity, but he was not credited with the discovery of nuclear fission. Ernest Rutherford conducted the famous gold foil experiment and made contributions to the understanding of the atom's structure, but he did not discover nuclear fission.

4. What happens to the speed of a sound wave when it travels from air to water?

Correct answer: B

Rationale: When a sound wave travels from air to water, the speed of sound decreases because sound travels faster in denser mediums. Water, being denser than air, causes the speed of sound to slow down. Choice A is incorrect because sound travels faster in denser mediums, so the speed would not increase. Choice C is incorrect because the speed of sound changes when transitioning between different mediums. Choice D is incorrect because while frequency does affect sound, the medium it travels through also plays a significant role in determining the speed of sound.

5. Which of the following is a pair of nerves that originates from the brain?

Correct answer: B

Rationale: The olfactory nerves, choice B, are a pair of cranial nerves that originate from the brain. They are responsible for the sense of smell and are the only cranial nerves that directly connect to the cerebrum. Spinal nerves, choice A, originate from the spinal cord, the sciatic nerve, choice C, is a large nerve that originates in the lower back, and the optic nerve, choice D, originates from the retina of the eye. Therefore, choices A, C, and D are incorrect as they do not originate directly from the brain.
