Biology

1. What is the process of converting glucose into ATP, the cell's primary energy currency, called?

Correct answer: A

Rationale: Rationale: A) Cellular respiration is the process by which cells convert glucose into ATP, the primary energy currency of the cell. This process involves a series of biochemical reactions that occur in the mitochondria of eukaryotic cells or the cytoplasm of prokaryotic cells. Through cellular respiration, the energy stored in glucose molecules is gradually released and captured in the form of ATP. B) Fermentation is an anaerobic process that occurs in the absence of oxygen. It involves the partial breakdown of glucose to produce ATP and end products such as lactic acid or ethanol. While fermentation can generate ATP, it is less efficient than cellular respiration in terms of energy production. C) Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose. This process occurs in chloroplasts and is the opposite of cellular respiration. While photosynthesis produces glucose,

2. What type of clause is "as the sun dipped below the horizon" in the sentence "We sat on the beach, as the sun dipped below the horizon"?

Correct answer: B

Rationale: The clause "as the sun dipped below the horizon" provides additional information about the main clause "We sat on the beach," making it a subordinate clause.

3. Recognize the opposing muscle pair.

Correct answer: A

Rationale: The bicep and tricep muscles are antagonistic muscle pairs, meaning they work in opposition to each other. The bicep is located on the front of the upper arm and is responsible for flexing the elbow joint. The tricep is located on the back of the upper arm and is responsible for extending the elbow joint.

4. A convex lens is characterized by its ability to:

Correct answer: A

Rationale: The correct answer is A: 'Converge light rays.' A convex lens is thicker in the center and thinner at the edges, causing light rays passing through it to converge or come together at a focal point. This ability is what enables convex lenses to bend light rays inward, focusing them to produce clear images. Options B and C are incorrect because convex lenses do not diverge light rays or focus sound waves. Option D is also incorrect as convex lenses can create both real and virtual images based on the position of the object with respect to the lens. Therefore, the main characteristic of a convex lens is its ability to converge light rays to form focused images.

5. During embryonic development, all tissues originate from

Correct answer: D

Rationale: During embryonic development, all tissues originate from the three primary embryonic germ layers: ectoderm, mesoderm, and endoderm. These layers give rise to all the different types of tissues found in the body. The ectoderm forms the skin and nervous system, the mesoderm gives rise to muscle, bone, and connective tissues, while the endoderm develops into the lining of the digestive and respiratory systems. Therefore, option D is the correct answer as it encompasses the comprehensive origin of all tissues in the body during embryonic development.

6. What happens to the work done on an object when the angle between force and displacement is 90 degrees?

Correct answer: b

Rationale: When the angle between force and displacement is 90 degrees, the work done on the object is zero.
