Answer the following question given this paragraph: The Epithelial Cell Epithelial cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces. Particular structures found in some epithelial cells are an adaptation to specific functions. Certain organelles are segregated to the basal sides, whereas other organelles and extensions, such as cilia, when present, are on the apical surface. Cilia are microscopic extensions of the apical cell membrane that are supported by microtubules. They beat in unison and move fluids as well as trapped particles. Ciliated epithelium lines the ventricles of the brain where it helps circulate the cerebrospinal fluid. The ciliated epithelium of your airway forms a mucociliary escalator that sweeps particles of dust and pathogens trapped in the secreted mucous toward the throat. It is called an escalator because it continuously pushes mucous with trapped particles upward. In contrast, nasal cilia sweep the mucous blanket down towards your throat. In both cases, the transported materials are usually swallowed, and end up in the acidic environment of your stomach. Q: What cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces? Choices: - mast cells - nerve cells - connective tissue - epithelial cells A:
epithelial cells
Q: Answer the following question given this paragraph: Lysosomes are like the recycling trucks that carry waste away from the factory.

A: digestive
Question: Answer the following question given this paragraph: The answer depends on if the cell is prokaryotic or eukaryotic. The main difference between the two types of cells is the presence of a nucleus. And in eukaryotic cells, DNA lives in the nucleus. Q: What is the main difference between prokaryotic or eukaryotic cells ? Choices: - the type of metabolic waste - the presence of cell walls - the presence of a Golgi Apparatus - the presence of a nucleus A:
Answer: the presence of a nucleus

Answer the following question given this paragraph: There are two main types of diabetes, type 1 diabetes and type 2 diabetes. Type 1 diabetes makes up about 5-10% of all cases of diabetes in the United States. Type 2 diabetes accounts for most of the other cases. Both types of diabetes are more likely in people that have certain genes. Having a family member with diabetes increases the risk of developing the disease. Q: How many main types of diabetes are there? Choices: - three - one - six - two A:
**Answer**
two
