| Question | Answer |
|---|---|
| The __ is the organelle responsible for controlling the activities of the cell by housing DNA. | nucleus |
| In cellular respiration, __ is produced as a byproduct of breaking down glucose. | carbon dioxide |
| The process of __ involves the division of a single cell into two identical daughter cells. | mitosis |
| __ transport requires energy to move substances across the cell membrane. | Active |
| In photosynthesis, plants convert sunlight into chemical energy stored as __. | glucose |
| Which organelle is primarily involved in energy production? | mitochondria |
| What is the process called when DNA is copied to produce RNA? | transcription |
| Which of the following macromolecules is primarily responsible for storing genetic information? | nucleic acids |
| The process of crossing over occurs before the first division in meiosis and increases _________ diversity. | genetic |
| Describe passive transport. | Movement of molecules down the concentration gradient without the use of energy. |
| Explain how the structure of the cell membrane contributes to its function in maintaining homeostasis. | The structure of the cell membrane |
| Describe the process of meiosis and its significance in genetic variability. | Meiosis involves the division of one diploid cell into four haploid cells that are all genetically unique. |
| How do environmental factors lead to heritable mutations? | Things like radiation, smoking, drinking alcohol, and eating processed foods can cause cancer which is a mutation that causes cells to divide out of control. |
| Discuss the roles of photosynthesis and respiration in the cycling of matter and flow of energy within a cell. | The products of photosynthesis are the reactants of cell respiration and the two processes work together to cycle carbon and oxygen through the atmosphere and biosphere. |
| Compare and contrast the advantages and disadvantages of sexual and asexual reproduction. | Sexual reproduction enhances genetic diversity (advantage) but requires a mate and is slower (disadvantage), while asexual reproduction is faster and doesn't need a mate (advantage) but increases extinction risk (disadvantage). |
