(A) Relative solubility of the component (B) Size and weight of the cellular component (C) Percentage of carbohydrates in the component (D) Presence or absence of lipids in the component (E) Density of the cellular component

4. All of the following are part of a prokaryotic cell EXCEPT? (A) Cell wall (B) Mitochondria (C) Plasma membrane (D) Endoplasmic reticulum (E) Ribosomes

5. What is the function of the nuclear pore complex found in eukaryotes? (A) It regulates the movement of proteins into and out of the nucleus (B) It synthesizes the proteins required to copy DNA and make mRNA (C) It selectively transports molecules out of the nucleus, but prevents all inbound molecules from entering the nucleus (D) It assembles ribosomes from raw materials that are synthesized in the nucleus (E) It regulates the movement of RNAs out of the nucleus

(A) Neurons that transmit nerve impulse (B) Muscle cells that contract to move bones (C) Pancreatic acinar cells that secret large amounts of digestive enzymes (D) Plasma cells that secret antibodies (E) Epithelial cells on the surface of the skin

複選題
7. Which of the following are TRUE for both chloroplasts and mitochondria? (A) have their own DNA (B) have double membrane structure (C) are part of the endomembrane system (D) are capable of reproducing themselves (E) The endosymbiont theory supports their evolutionary origins

複選題
8. Which of the following contain the "9 + 2" arrangement of microtubules, consisting of nine doublets of microtubules surrounding a pair of single microtubules? (A) Flagella and (B) Primary (nonmotile) cilia (C) Motile cilia (D) Centrioles (E) Basal bodies

9. The extracellular matrix is thought to participate in the regulation of animal cell behavior by communicating information from the outside to the inside of the cell via which of the following? (A) Gap junctions (B) Integrins (C) Desmosomes (D) Microfilaments (E) Tight junctions

複選題
10. Cell membranes are asymmetrical. Which of the following statements are the most likely explanations for the membrane's asymmetrical nature? (A) Since the cell membrane forms a border between one cell and another in tightly packed tissues such as epithelium, the membrane must be asymmetrical. (B) Since cell membranes communicate signals from one organism to another, the cell membranes must be asymmetrical. (C) The two sides of a cell membrane face different environments and carry out different functions. (D) Proteins only function on the cytoplasmic side of the cell membrane, which results in the membrane's asymmetrical nature. (E) The two sides of membrane are structurally different. Different phospholipids are found in each side of the membrane.
