1. When you push a book across a table, the book experiences an equal and opposite force from the table. Why doesn't the table move as well?
- A. The table is much heavier than the book.
- B. The force on the book acts in a different direction.
- C. The table has a much larger surface area, distributing the force over a wider area
- D. All of the above
Correct answer: C
Rationale: While Newton's third law states that for every action, there is an equal and opposite reaction, the unbalanced force acting on each object depends on their respective masses. The larger mass of the table (compared to the book) experiences a smaller acceleration, making its movement almost imperceptible.
2. The ureters are paired tubes that transport urine from the:
- A. Bladder to the urethra
- B. Kidneys to the bladder
- C. Urethra to the kidneys
- D. Skin to the kidneys
Correct answer: B
Rationale: The correct answer is B: 'Kidneys to the bladder.' The ureters are paired tubes that carry urine from the kidneys to the bladder. Once urine is produced in the kidneys, it travels through the ureters to be stored in the bladder until it is eliminated from the body through the urethra. Option A, 'Bladder to the urethra,' is incorrect because the ureters transport urine from the kidneys to the bladder, not from the bladder to the urethra. Option C, 'Urethra to the kidneys,' and option D, 'Skin to the kidneys,' are both inaccurate as they do not describe the correct direction of urine flow in the urinary system. Understanding the anatomy and function of the urinary system is essential for comprehending how urine is produced and excreted by the body.
3. What does "monophyletic" mean in the context of classification?
- A. A group with a single representative organism
- B. A group with diverse and unrelated members
- C. A group with similar functions but different origins
- D. A group descended from a common ancestor
Correct answer: D
Rationale: Rationale: In the context of classification, "monophyletic" refers to a group that includes a common ancestor and all of its descendants. This group shares a single evolutionary origin and forms a complete branch on a phylogenetic tree. Monophyletic groups are considered natural and valid taxonomic units because they reflect evolutionary relationships accurately. Option D is the correct choice as it accurately defines the term "monophyletic" in the context of classification.
4. What is the breakdown product of creatine phosphate, an energy source used for short bursts of muscle activity?
- A. Glucose
- B. Lactic acid
- C. Carbon dioxide
- D. Creatine
Correct answer: D
Rationale: The breakdown product of creatine phosphate is creatine. Creatine phosphate is stored in muscle cells and rapidly converts to creatine to provide energy for short bursts of muscle activity, such as weightlifting or sprinting. It is not converted into glucose, lactic acid, or carbon dioxide. Creatine is then further broken down into creatinine, which is excreted in urine. Therefore, the correct answer is D: Creatine.
5. What are the two main types of nuclear decay, and what differentiates them?
- A. Fission and fusion, based on the size of the nucleus
- B. Alpha and beta decay, based on the emitted particle.
- C. Spontaneous and induced decay, based on the trigger.
- D. Isotope decay and chain reactions, based on the stability of the nucleus.
Correct answer: B
Rationale: The two main types of nuclear decay are alpha and beta decay, based on the emitted particle. In alpha decay, an alpha particle (which consists of two protons and two neutrons) is emitted from the nucleus. In beta decay, a beta particle (either an electron or a positron) is emitted from the nucleus. These types of decay are differentiated by the particles they emit, rather than the size of the nucleus, trigger, or stability of the nucleus.
6. What is the process of cells restoring damaged or lost tissues called?
- A. Cell division
- B. Cell differentiation
- C. Cell growth
- D. Cell regeneration
Correct answer: D
Rationale: Rationale: A) Cell division refers to the process by which a cell divides into two daughter cells. B) Cell differentiation is the process by which cells become specialized for specific functions. C) Cell growth is the increase in cell size or number. D) Cell regeneration is the process of cells restoring damaged or lost tissues by replacing or repairing the damaged cells. This process is essential for healing wounds and maintaining tissue integrity.
