Hi. Could you please help me answer number 3. Preferably if familiar with Seeleys anatomy and physiology
For each of the following scenarios please describe which part of the cell theory is supported by this evidence. Options: • • • Cells come from preexisting cells, cells are the basic unit of life, all living things are made of cells 1. A botanist (plant scientists) named Schlieden studied a large variety of plant cells under the microscope and found that all plants were made of cells. Option 1 2. A scientist named Leeuwenhoek found that after studying a wide variety of organisms the smallest living organism he observed was made of only one cell. Option 1 3. A scientist named Virchow viewed cells under a microscope and found that cells would grow and split into new cells. Option 1 4. A zoologist (animal scientist) looked at a large amount of different animal tissues under a microscope and found that all animals are made of cells. Option 1 5. Robert Hooke studied cork and many other substances and found that they contained little square boxes he called cells. Option 1
Membrane Physiology Homework 1. You have a beaker filled with a solution containing 2M glucose, 4M urea and IM salt. Suspended in the solution is a cell that containing a solution of IM glucose, 8M urea and 3M salt. The membrane of the cell is permeable to glucose and salt but not urea. Answer each of the following questions: a. Where will water move? b. Where will urea move? c. Where will glucose move? d. Where will salt move? e. What will happen to the volume of fluid inside the cell? f. What will happen to the osmolarity of the fluid inside the cell?

Read This! When phospholipids are added to an aqueous environment (consisting mostly of water) the phospholipid molecules will spontaneously assemble into a phospholipid bilayer where the layers are held together by weak attractive forces between molecules. These structures are often seen in nature as cell and organelle membranes. 12. Consider animal cells, which are only bound by a cell membrane and plant cells which are bound by both a cell membrane and a cell wall. Are cell membranes flexible (fluid)? Provide specific examples to support your answer. 13. Explain why a phospholipid bilayer is flexible. terms of the strength of the forces that hold it together. 14. Refer to Model 1. a. What happens to the shape of the hydrophobic tail in a phospholipid when a double bond is present in the carbon chain? b. Explain why the flexibility (fluidity) of a membrane increases when more of the phospholipids in the layers contain double bonds. 15. The diagram below shows the chemical structure…
