Answer the following question given this paragraph: The cytoskeleton is a cellular "scaffolding" or "skeleton" that crisscrosses the cytoplasm. All eukaryotic cells have a cytoskeleton, and recent research has shown that prokaryotic cells also have a cytoskeleton. The eukaryotic cytoskeleton is made up of a network of long, thin protein fibers and has many functions. It helps to maintain cell shape, holds organelles in place, and for some cells, it enables cell movement. The cytoskeleton plays important roles in both the intracellular movement of substances and in cell division. Certain proteins act like a path that vesicles and organelles move along within the cell. The threadlike proteins that make up the cytoskeleton continually rebuild to adapt to the cell's constantly changing needs. Three main kinds of cytoskeleton fibers are microtubules, intermediate filaments, and microfilaments. Q: The cytoskeleton is a cellular "scaffolding" or "skeleton" that crisscrosses what? Choices: - golgi apparatus - cerebellum - cell membrane - cytoplasm A:
**Answer**
cytoplasm

*Question*
Answer the following question given this paragraph: Gases are composed of tiny particles that are separated by large distances. Gas particles are constantly moving, experiencing collisions with other gas particles and the walls of their container. The velocity of gas particles is related to the temperature of a gas. Gas particles do not experience any force of attraction or repulsion with each other. Q: What state of matter is characterized by tiny particles separated by large distances, which do not experience any force of attraction or repulsion with each other? Choices: - steam - emissions - liquids - gas A:
**Answer**
gas

*Question*
Answer the following question given this paragraph: Any two waves in the same medium undergo wave interference as they pass each other. At the location where the two waves collide, the result is essentially a summation of the two waves. In some places, a wave crest from one source will overlap a wave crest from the other source. Since both waves are lifting the medium, the combined wave crest will be twice as high as the original crests. Nearby, a wave trough will overlap another wave trough and the new trough will be twice as deep as the original. This is called constructive interference because the resultant wave is larger than the original waves. Within the interference pattern, the amplitude will be twice the original amplitude. Once the waves pass through each other and are alone again, their amplitudes return to their original values. Q: What is it called when two waves in the same medium pass one another? Choices: - accumulation - frequency - synchrony - interference A:
**Answer**
interference
