1. What is the general formula for an alkyl halide?

• A. Câ‚™Hâ‚‚â‚™
• B. Câ‚™H₂ₙ₊₂
• C. Câ‚™H₂ₙ₊₁X
• D. Câ‚™Hâ‚‚â‚™O

Correct answer: C

Rationale: The correct answer is option C, 'CₙH₂ₙ₊₁X.' This is the general formula for an alkyl halide, where X represents a halogen atom (such as fluorine, chlorine, bromine, or iodine), and the hydrocarbon chain is represented by CₙH₂ₙ₊₁. Option A, 'CₙH₂ₙ,' is incorrect because it does not account for the presence of a halogen atom. Option B, 'CₙH₂ₙ₊₂,' is incorrect as it represents an alkene, not an alkyl halide. Option D, 'CₙH₂ₙO,' is also incorrect as it suggests the presence of oxygen, which is not characteristic of alkyl halides.

2. In the sentence, 'The receptionist explained that we would be the next to see the doctor,' which of the following is the complete predicate?

• A. explained that we would be the next to see the doctor
• B. next to see the doctor
• C. explained that we would be next
• D. see the doctor

Correct answer: A

Rationale: The complete predicate is 'explained that we would be the next to see the doctor.' In a sentence, the complete predicate includes the main verb (explained) and all the words that complete its meaning (that we would be the next to see the doctor). Choices B, C, and D do not constitute the complete predicate as they do not include the main verb 'explained' and all associated words that complete its meaning.

3. Which organelle is responsible for carrying out photosynthesis in plant cells?

• A. Golgi apparatus
• B. Mitochondria
• C. Chloroplasts
• D. Lysosomes

Correct answer: C

Rationale: A) Golgi apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for secretion or for use within the cell. It is not involved in photosynthesis. B) Mitochondria: Mitochondria are known as the powerhouse of the cell and are responsible for generating energy in the form of ATP through cellular respiration. They are not involved in photosynthesis. C) Chloroplasts: Chloroplasts are the organelles responsible for carrying out photosynthesis in plant cells. They contain chlorophyll, a pigment that captures light energy and converts it into chemical energy in the form of glucose. D) Lysosomes: Lysosomes are membrane-bound organelles that contain digestive enzymes to break down waste materials and cellular debris. They are not involved in photosynthesis. Therefore, the correct answer is C) Chloroplasts, as they are specifically responsible for carrying out photosynthesis in plant

4. Which organ stores and concentrates bile?

• A. Liver
• B. Gallbladder
• C. Pancreas
• D. Stomach

Correct answer: B

Rationale: The correct answer is B: Gallbladder. The gallbladder is the organ that stores and concentrates bile produced by the liver. Bile is essential for the digestion of fats in the small intestine. The liver produces bile, which is then stored and concentrated in the gallbladder until it is released into the small intestine when needed. Choices A, C, and D are incorrect because the liver produces bile, the pancreas produces digestive enzymes, and the stomach is primarily involved in the digestion of food through acid secretion and mechanical processes, not in storing bile.

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

• A. Muscles
• B. Tendons
• C. Ligaments
• D. Cartilage

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.
