How can you tell?You are using a computer program to design a new single-celled organism. Discuss why a flat, plate-like cell will be more efficient in transporting materials than a spherical, ball-like cell of the same volume.Examine the diagrams of the animal cell below. In each case, identify the cell as being in an isotonic solution, a hypertonic solution, or a hypotonic solution. Then write a caption in your own words for each cell to explain what is happening as a result of being in that solution.

- Use the information below to answer the question Cell A = 1 μm x 1 μm x 1 μm Cell B=2 µm x 2 μm x 2 μm Cell C = 3 μm x 3 μm x 3 um How do the surface area-to-volume ratios compare for the cells listed above, and which cell would exchange the greatest amount of substances and waste products with its environment relative to its internal chemical activity? Assume the cells are cube-like. O a. The surface area-to-volume ratios increase from A to B to C, with cell A having the most rapid transport. O b. The surface area-to-volume ratios increase from A to B to C, with cell B having the most rapid transport O c. The surface area-to-volume ratios increase from A to B to C, with cell C having the most rapid transport O d. The surface area-to-volume ratios increase from C to B to A, with cell A having the most rapid transport. Oe. The surface area-to-volume ratios increase from C to B to A, with cell C having the most rapid transportAs an environmental engineer, you will follow the scientific method and start your work by generating a hypothesis first. Formulate a hypothesis on how bacterial cells use their characteristics to take up hydrocarbons from oil spills. Specify the mode of transport through the cell membrane (active vs. passive/endocytosis vs. exocytosis) and support your claim with scientific reasoning. Describe how these bacterial cells would take up hydrocarbons if: they only possessed a cell membrane and lacked the cell wall. they possessed membrane-bound organelles such as vesicles. Include in your answer the lipid bilayer, structural components of cell membranes and those of cell walls, and discuss the selective permeability characteristic of membranes.A wilted flower placed in a vase of fresh hwater for several hours became stiff and stood erect.
