1. The renal system consists of all the organs involved in the formation and release of urine and includes the kidneys, ureters, bladder, and urethra.

• A. The digestive system
• B. The reproductive system
• C. The renal system
• D. The kidney system

Correct answer: C

Rationale: The correct term for the system involving the organs responsible for the formation and release of urine is the renal system, not the digestive or reproductive system. The kidneys, ureters, bladder, and urethra are specifically part of the renal system, which is responsible for filtering the blood to remove waste and excess fluids, producing urine, and eliminating it from the body. The other choices, the digestive system and the reproductive system, are not responsible for the formation and release of urine, making them incorrect answers.

2. What is the second part of an organism’s scientific name?

• A. species
• B. phylum
• C. population
• D. kingdom

Correct answer: A

Rationale: The correct answer is 'species.' In binomial nomenclature, the second part of an organism's scientific name represents its species. The species name is a unique identifier within the genus and helps differentiate between different organisms within the same genus. Choices B, C, and D are incorrect. Phylum is a taxonomic rank higher than species, population refers to a group of organisms of the same species living in the same area, and kingdom is a taxonomic rank higher than genus.

3. What is the effect of the Earth's rotation on the atmosphere and on all objects on the Earth's surface?

• A. The Coriolis effect
• B. The Corona effect
• C. The Archimedes effect
• D. The tidal effect

Correct answer: A

Rationale: The Coriolis effect is the effect of the Earth's rotation on the atmosphere and on all objects on the Earth's surface. It causes moving objects and currents to be deflected to the right in the northern hemisphere and to the left in the southern hemisphere. This deflection is a result of the rotation of the Earth and plays a crucial role in influencing weather patterns and ocean currents around the globe. The other choices provided are incorrect. The Corona effect is related to the Sun's atmosphere, the Archimedes effect involves buoyancy in fluids, and the tidal effect is associated with the gravitational forces between the Earth, the Moon, and the Sun.

4. Why does cytokinesis happen?

• A. DNA can duplicate
• B. Organelles can convert energy
• C. Bacteria can be killed
• D. Daughter cells can divide

Correct answer: D

Rationale: Cytokinesis happens at the end of mitosis to physically separate the newly formed daughter cells. This allows the cell to divide into two separate daughter cells, each containing a complete set of genetic material (DNA) and organelles. The purpose of cytokinesis is to ensure that each daughter cell receives the necessary components to function independently. Choices A, B, and C are incorrect because cytokinesis does not directly involve DNA duplication, organelles converting energy, or killing bacteria.

5. Which organelle is responsible for organizing protein synthesis?

• A. Nucleus
• B. Ribosome
• C. Lysosome
• D. Vacuole

Correct answer: B

Rationale: The correct answer is B: Ribosome. Ribosomes are responsible for organizing protein synthesis by assembling amino acids. They are the cellular machinery where proteins are synthesized. The other choices, such as the nucleus, lysosome, and vacuole, do not directly participate in protein synthesis. The nucleus contains DNA and controls cell activities, the lysosome is involved in digestion and waste removal, and the vacuole is responsible for storage and maintaining cell turgor pressure.
