Biology Practice Test

1. What is located on the rough endoplasmic reticulum?

Correct answer: D

Rationale: The rough endoplasmic reticulum is studded with ribosomes, not microvilli, mitochondria, or lysosomes. Ribosomes are responsible for protein synthesis, making them an essential component of the rough endoplasmic reticulum.

2. Which of the following options correctly lists biology's hierarchical organizational system?

Correct answer: B

Rationale: The correct hierarchical organizational system in biology is Kingdom, Phylum, Class, Order, Family, Genus, and Species. This follows the mnemonic 'King Phillip Came Over For Good Soup.' Choice A is incorrect as it does not follow the correct hierarchical order. Choice C is incorrect as it starts with Genus, which is more specific and should come after Family. Choice D is incorrect as it does not follow the correct hierarchical order.

3. What is the liquid found inside the cell?

Correct answer: D

Rationale: The correct answer is D, Cytosol. Cytosol is the liquid component of the cytoplasm where various cellular processes occur. Choices A, B, and C are incorrect because the plasma membrane is the outer boundary of the cell, cilia are hair-like structures on the cell surface, and cytoplasm is the jelly-like substance that contains organelles within the cell, not the liquid inside the cell.

4. Why does ice have the capability of floating on water?

Correct answer: D

Rationale: The correct answer is D. Ice forms a lattice structure when it freezes, which makes it less dense than liquid water, allowing it to float. Choice A is incorrect because viscosity refers to a fluid's resistance to flow and is not related to ice floating. Choice B is incorrect as ice and liquid water have the same chemical composition (H2O). Choice C is incorrect because the high specific heat of water is not the reason why ice floats.

5. In the hierarchy of biology, cells combine to form which of the following?

Correct answer: C

Rationale: In the hierarchy of biology, cells combine to form tissues. Tissues are groups of cells that work together to perform specific functions. This is a fundamental level of organization above individual cells but below organs and organ systems. Macromolecules and molecules are smaller components that make up cells, not what cells combine to form. Organelles are structures within cells that perform specific functions and do not result from the combination of cells.
