Biology Practice: The Cell (Mock Test 4 - Advanced Reasoning)
1. Why does a cell remain microscopic in size rather than growing as large as a tennis ball?
2. If a microscope can distinguish two points that are 2 Angstroms apart, this ability is known as:
3. Reasoning: Why do cells in the small intestine have "Microvilli" (finger-like folds)?
4. Which part of the nuclear envelope is continuous with the Rough Endoplasmic Reticulum?

11. A cell is placed in a solution and begins to shrink (plasmolysis). The solution is:
12. Which filament of the cytoskeleton anchors the nucleus in a fixed position?
13. In the "Central Dogma," where does the process of "Translation" occur?
14. What provides the "woodiness" and extreme rigidity to the Secondary Cell Wall of plants?
