1. Which of the following is not true of mitosis?
- A. Mitosis produces daughter cells
- B. Mitosis has five main stages
- C. Mitosis can only be done by haploids
- D. Following mitosis, daughter cells are identical to parent cells
Correct answer: C
Rationale: The correct answer is C. Mitosis occurs in diploid cells and involves stages that result in the production of two identical daughter cells. Haploids do not undergo mitosis, as mitosis is a process specific to diploid cells. Choice A is true as mitosis does produce daughter cells. Choice B is incorrect as mitosis typically consists of four main stages: prophase, metaphase, anaphase, and telophase. Choice D is true, as one of the main outcomes of mitosis is the production of daughter cells that are genetically identical to the parent cell.
2. Which of the following options identifies the products of cell respiration?
- A. Water, carbon dioxide, and oxygen
- B. Glucose and oxygen
- C. Water, carbon dioxide, and adenosine triphosphate (ATP)
- D. Water, glucose, and oxygen
Correct answer: C
Rationale: The correct answer is C: 'Water, carbon dioxide, and adenosine triphosphate (ATP).' During cellular respiration, glucose is broken down in the presence of oxygen to produce water, carbon dioxide, and ATP. Choice A is incorrect as oxygen is not a product of cell respiration but a reactant. Choice B is incorrect as it lists glucose and oxygen, which are actually reactants in the process. Choice D is incorrect as glucose is not a product of cell respiration but a substrate that is broken down to release energy.
3. Which of the following statements is true if a molecule exhibits adhesion?
- A. Two molecules of the same substance have the ability to stay bonded to one another
- B. The molecule has the ability to bond to or attract other molecules
- C. A molecule has the ability to increase its heat when necessary
- D. The molecule has the ability to form hydrogen bonds
Correct answer: B
Rationale: The correct statement is that if a molecule exhibits adhesion, it has the ability to bond to or attract other molecules. Adhesion refers to the ability of a molecule to bind to or attract different types of molecules. Choice A is incorrect because adhesion is about bonding to different molecules, not the same substance. Choice C is incorrect as adhesion does not relate to the ability of a molecule to increase its heat. Choice D is incorrect because forming hydrogen bonds is a specific type of interaction and not a general characteristic of molecules exhibiting adhesion.
4. What is the primary method of asexual reproduction used by most bacteria?
- A. Meiosis
- B. Mitosis
- C. Binary fission
- D. Interphase
Correct answer: C
Rationale: The correct answer is C: Binary fission. This is the main process through which most bacteria reproduce asexually. During binary fission, a single cell divides into two identical cells, each containing a copy of the genetic material. Choices A and B, meiosis and mitosis, are processes involved in sexual reproduction and are not used by bacteria for asexual reproduction. Choice D, interphase, is a stage of the cell cycle where the cell prepares for division and is not a method of reproduction.
5. Which of the following options correctly lists the five stages of mitosis in order from beginning to end?
- A. Prophase, Prometaphase, Telophase, Metaphase, Anaphase
- B. Prophase, Prometaphase, Metaphase, Anaphase, Telophase
- C. Metaphase, Anaphase, Prophase, Prometaphase, Telophase
- D. Metaphase, Telophase, Anaphase, Prophase, Prometaphase
Correct answer: B
Rationale: The correct order of the stages of mitosis is Prophase, Prometaphase, Metaphase, Anaphase, and Telophase. Choice A is incorrect because it has Anaphase and Metaphase in the wrong order. Choice C is incorrect as it starts with Metaphase, which is not the first stage of mitosis. Choice D is incorrect as it also has the stages in the wrong order, and it starts with Metaphase, which is incorrect.
