1. According to Newton's third law of motion, if you push against a wall with a certain force, the wall will push back with:

Correct answer: B

Rationale: According to Newton's third law of motion, for every action, there is an equal and opposite reaction. When you push against a wall with a certain force, the wall will push back on you with an equal force in the opposite direction. Choice A is incorrect because the wall exerts an equal force back. Choice C is incorrect as it suggests a greater force, which goes against Newton's third law. Choice D is incorrect as the wall does exert a force back in response to your push.

2. Which structure of the endocrine system is responsible for maturing T cells?

Correct answer: C

Rationale: The thymus is the primary gland responsible for the maturation of T cells in the immune system. T cells are a type of white blood cell involved in the immune response. The hypothalamus is primarily involved in hormone regulation and maintaining homeostasis. The pineal gland is responsible for secreting melatonin and regulating the sleep-wake cycle. The thyroid gland plays a key role in metabolism regulation through the production of thyroid hormones. Therefore, the correct answer is the thymus because it is specifically associated with the maturation of T cells, making it essential for proper immune function.

3. What is the main component of sweat?

Correct answer: C

Rationale: - Sweat is primarily composed of water, making up the majority of its content. Water helps regulate body temperature by evaporating from the skin's surface, which cools the body down. - While sweat does contain small amounts of other substances like urea, glucose, and electrolytes, water is the main component that is secreted by sweat glands to help regulate body temperature during physical activity or in response to heat.

4. Follow the instructions below to transform the starting word into a different word. Start with the word ESOTERIC. Remove both instances of the letter E from the word. Remove the letter I from the word. Move the letter T from the middle of the word to the end of the word. Remove the letter C from the word. What word remains?

Correct answer: B

Rationale: The word ESOTERIC is transformed into SORT by following the instructions provided. Firstly, both instances of the letter E are removed, then the letter I is also removed. Next, the letter T, originally in the middle of the word, is moved to the end. Lastly, the letter C is removed. Among the options, only 'SORT' fits all the criteria given in the instructions. Choices A, C, and D do not accurately reflect the modifications made to the original word.

5. Which organelle in the cell is responsible for producing energy in the form of ATP?

Correct answer: B

Rationale: The correct answer is B: Mitochondria. Mitochondria are known as the powerhouses of the cell and are responsible for producing energy in the form of ATP through cellular respiration. ATP is the primary energy currency of the cell, powering various cellular activities. The nucleus (choice A) is responsible for housing the cell's genetic material but is not involved in ATP production. Ribosomes (choice C) are involved in protein synthesis, not energy production. The Golgi apparatus (choice D) is responsible for modifying, sorting, and packaging proteins for secretion, not for ATP production.
