Biology
1. Which organelle is responsible for packaging and secreting proteins into the extracellular space?
- A. Golgi apparatus
- B. Mitochondria
- C. Ribosomes
- D. Endoplasmic reticulum
Correct answer: A
Rationale: Rationale: A) Golgi apparatus: The Golgi apparatus is responsible for modifying, sorting, and packaging proteins into vesicles for secretion outside the cell or for use within the cell. 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 packaging and secreting proteins. C) Ribosomes: Ribosomes are responsible for protein synthesis, where they translate mRNA into proteins. They are not involved in packaging and secreting proteins into the extracellular space. D) Endoplasmic reticulum: The endoplasmic reticulum (ER) plays a role in protein synthesis and folding, but it is the rough ER specifically that is involved in synthesizing proteins that are then transported to the Golgi apparatus for further processing and packaging. The Golgi apparatus is primarily responsible for packaging and secreting proteins
2. Identify the preposition in the following sentence: The cat jumped over the fence.
- A. cat
- B. jumped
- C. over
- D. the
Correct answer: C
Rationale: Prepositions show the relationship between a noun or pronoun and another word in the sentence. "Over" indicates the position of the cat in relation to the fence.
3. Which gland located in the neck is responsible for regulating metabolism, growth, and development?
- A. Parathyroid gland
- B. Thyroid gland
- C. Pituitary gland
- D. Thymus gland
Correct answer: B
Rationale: The correct answer is B: Thyroid gland. The thyroid gland is located in the neck and plays a crucial role in regulating metabolism, growth, and development. It produces hormones such as thyroxine (T4) and triiodothyronine (T3) that control the body's metabolic rate, affecting energy levels and growth. The parathyroid gland (A) regulates calcium levels in the body, the pituitary gland (C) controls several other glands and their hormone production, and the thymus gland (D) is involved in the immune system's development. Therefore, the thyroid gland is the most appropriate choice for the functions described in the question.
4. What is the difference between a prokaryotic cell and a eukaryotic cell?
- A. Prokaryotic cells have a nucleus, while eukaryotic cells do not
- B. Eukaryotic cells have a nucleus, while prokaryotic cells do not.
- C. Prokaryotic cells have membrane-bound organelles, while eukaryotic cells do not.
- D. Eukaryotic cells have membrane-bound organelles, while prokaryotic cells do not.
Correct answer: B
Rationale: Rationale: - Prokaryotic cells are simpler and do not have a true nucleus. Their genetic material is located in the nucleoid region, which is not enclosed by a membrane. - Eukaryotic cells are more complex and have a true nucleus that houses the genetic material, enclosed within a nuclear membrane. - Both prokaryotic and eukaryotic cells have organelles, but eukaryotic cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus, while prokaryotic cells lack these membrane-bound organelles.
5. Which of the following is an example of a secondary alcohol?
- A. Methanol
- B. Ethanol
- C. Isopropanol
- D. Butanol
Correct answer: C
Rationale: Isopropanol is an example of a secondary alcohol, as the hydroxyl group is attached to a carbon atom that is bonded to two other carbon atoms. The other choices are primary alcohols.
6. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."
- A. "My biggest fear"
- B. "that I wouldn't live life to the fullest"
- C. "life"
- D. "the fullest"
Correct answer: B
Rationale: Option B functions as the object of the verb "is," making it a noun clause.
