1. Which of the following nutrients is correctly matched with its foundational components?

Correct answer: D

Rationale: Proteins consist of strings of amino acids. Amino acids are the basic building blocks of proteins, and they are linked together in a specific sequence to form a protein structure. This is a correct match between the nutrient (proteins) and its foundational components (amino acids). Choices A, B, and C are incorrect as they do not accurately match the foundational components of the respective nutrients. Carbohydrates are not formed by glucose molecules bonding together; they are made up of sugar molecules. Lipids consist of fatty acids and glycerol, but they are not nutrients typically associated with bonding for formation. Nucleic acids do consist of nitrogenous bases, sugar, and phosphate groups, but they are not the correct match for the question.

2. What type of bone is the kneecap (patella)?

Correct answer: C

Rationale: The correct answer is C: Flat bone. The kneecap (patella) is classified as a flat bone. Flat bones are thin, flattened bones that provide protection and offer a broad surface for muscle attachment. The patella fits this description as it is a flat, triangular bone located in front of the knee joint, protecting the knee and providing attachment points for muscles like the quadriceps. Choice A, long bone, is incorrect as long bones are typically found in the arms and legs, not in the knee area. Choice B, short bone, is incorrect as short bones are cube-shaped and are not characteristic of the patella. Choice D, irregular bone, is incorrect as irregular bones have complex shapes and do not apply to the flat, triangular structure of the patella.

3. What is apoptosis, and how is it involved in embryonic development?

Correct answer: B

Rationale: Apoptosis is the process of programmed cell death, not uncontrolled cell growth (Choice A). It plays a vital role in embryonic development by eliminating unnecessary or damaged cells, sculpting organs, and ensuring proper tissue organization. Through apoptosis, the embryo undergoes controlled cell death to shape structures accurately. This mechanism is essential for the precise development of organs and tissues, emphasizing the significance of apoptosis in embryogenesis. DNA replication (Choice C) and cell division (Choice D) are essential cellular processes but are not directly related to apoptosis or its role in embryonic development.

4. How does kinetic energy change when the velocity of an object is doubled?

Correct answer: B

Rationale: Kinetic energy is directly proportional to the square of the velocity of an object according to the kinetic energy formula (KE = 0.5 * m * v^2). When the velocity is doubled, the kinetic energy increases by a factor of 2^2 = 4. Therefore, the kinetic energy quadruples when the velocity of an object is doubled. Choice A is incorrect because halving the kinetic energy would be the result if the velocity was halved, not doubled. Choice C is incorrect because doubling the velocity would result in a fourfold increase in kinetic energy, not just a double. Choice D is incorrect because kinetic energy is directly related to the velocity of an object, so if the velocity changes, the kinetic energy changes accordingly.

5. Which of the following structures connects muscle to bone?

Correct answer: B

Rationale: Tendons are the correct answer as they are fibrous structures that connect muscle to bone, enabling the transmission of force during movement. Ligaments, on the contrary, connect bone to bone, aiding in joint stability. Muscles contract to generate force and facilitate movement, while bones provide structural support and protect internal organs.
