1. Tendonitis is an inflammation of which part of the body?

Correct answer: B

Rationale: Tendonitis specifically refers to the inflammation of tendons, which are the thick cords that connect muscles to bones. The correct answer is tendons. Choice A, muscles, are not affected in tendonitis, but rather in myositis, which is the inflammation of muscles. Ligaments (Choice C) connect bones to other bones, while cartilage (Choice D) is a smooth and flexible tissue that covers the ends of bones at a joint. Therefore, the correct term for inflammation of tendons is tendonitis.

2. What happens to the internal energy of a system when it performs work on its surroundings?

Correct answer: B

Rationale: When a system performs work on its surroundings, it loses energy in the form of work done. This results in a decrease in the internal energy of the system. Work done by the system is considered as negative work, leading to a decrease in internal energy. Therefore, the correct answer is that the internal energy decreases when a system performs work on its surroundings. Choice A is incorrect as the internal energy decreases, not increases. Choice C is incorrect because the internal energy changes due to the work done. Choice D is incorrect because the information provided is sufficient to determine the change in internal energy.

3. Which of the following is an effect of high blood pressure?

Correct answer: C

Rationale: The correct answer is C: Renal vessel damage. High blood pressure can lead to damage in blood vessels throughout the body, including the kidneys. When blood vessels in the kidneys are affected, it can impair kidney function and potentially lead to kidney disease. Smoking (Choice A) and excessive dietary salt (Choice B) can contribute to high blood pressure but are not direct effects of high blood pressure itself. Older age (Choice D) is a risk factor for developing high blood pressure but is not a direct effect of high blood pressure.

4. Where does glycolysis occur within the cell?

Correct answer: A

Rationale: Glycolysis occurs in the cytosol, the liquid component of the cytoplasm, not in the nucleus, mitochondria, or endoplasmic reticulum. It is the initial step in cellular respiration and involves the breakdown of glucose into pyruvic acid. The process takes place in the cytosol as it does not require membrane-bound organelles like the mitochondria or endoplasmic reticulum for its completion.

5. Which type of blood cell is primarily responsible for fighting infections?

Correct answer: B

Rationale: The correct answer is B: White blood cell. White blood cells are the primary cells responsible for fighting infections and foreign invaders in the body. Red blood cells carry oxygen to tissues, platelets help in blood clotting to prevent excessive bleeding, and plasma is the liquid component of blood that carries cells and nutrients. White blood cells, also known as leukocytes, play a crucial role in the immune system by identifying and destroying pathogens, such as bacteria, viruses, and other harmful substances. Therefore, they are the key players in the body's defense against infections, making them the correct answer in this scenario. While red blood cells, platelets, and plasma have essential functions in the body, they are not primarily responsible for combating infections like white blood cells.
