What is one way membrane phospholipids help the cell maintain homeostasis? They help exclude many large molecules. They prevent oxygen from entering the cell. They make the membrane fully permeable. They make the cell impermeable to viruses. --------------------------------------------------------------------------------24. Which statement is part of the cell theory? A cell must be smaller than 10 µm. Living things contains one or more cells. A cell is anything that contains genetic material. The cells of a multicellular organism are identical. --------------------------------------------------------------------------------25. A mature red blood cell does not contain a nucleus. What can you infer about mature red blood cells? They are unable to produce new proteins. They are not affected by hypertonic solutions. They have more chromosomes than immature red blood cells. They are unable to exchange gases across the cell membrane. --------------------------------------------------------------------------------26. A botanist is studying the effects of a chemical that destroys the rough endoplasmic reticulum. What would be the most immediate effect of the destruction of the rough ER? Poisons would not be detoxified. The cell would be unable to produce ATP. Waste products would overwhelm the cell. The cell would be unable to export proteins. --------------------------------------------------------------------------------27. Using a microscope, Lee counts 12 chromosomes in a cell that has just completed the M phase of the cell cycle. Which statement most likely describes the cell at the end of the S phase? It will have 6 chromatids. It will have 12 chromatids. It will have 24 chromatids. It will have 48 chromatids. --------------------------------------------------------------------------------28. A cell contains 16 replicated chromosomes at the beginning of mitosis. How many chromosomes will it have after cell division is complete? 8 16 24 32 --------------------------------------------------------------------------------29. Maria watches through a microscope as a vesicle within a cell fuses with the cell membrane and expels a large molecule. What process is Maria witnessing? exocytosis endocytosis pinocytosis phagocytosis --------------------------------------------------------------------------------30. Many vesicles within a cell contain digestive enzymes that break down ingested food particles. What process complements the function of these vesicles? exocytosis endocytosis pinocytosis phagocytosis --------------------------------------------------------------------------------

people dont want to do your hw here

ya, stop doing your hw from other people. and start doing it yourself.

If you review your course materials with these qq in mind, take notes where relevant, and answer them, this will cause small, still poorly understood, changes in your brain. The process is called LEARNING and is the entire point of the expensive and obviously difficult process of giving you an education.
