- A dialysis bag contains 10% starch solution. The dialysis bag is placed in a beaker filled with deionized water. Ten drops of Starch indicator (iodine solution, KI) solution is placed into the deionized water. The water turns a yellowish-brown color, however, you notice that the starch solution begins to turn black. Describe what is happening with respect to the diffusion of starch.a. Define diffusion. Is diffusion a passive or an active process? Explain how solute moves in this way. b. Use your knowledge of diffusion to explain what happened over time when you observed a crystal of methylene blue dropped into a beaker of water. Be sure to use equilibrium in your explanation. c. Explain your observations over time after a drop of methylene blue and a drop of potassium permanganate were placed in the agar. What factors affect the rate of diffusion? d. What are tissues? Name the four major types of tissues in the human body. e. Name the three primary germ layers. Name the primary germ layers from which epithelial tissues and connective tissues develop. f. List general characteristics that all epithelial tissues have in common. g. Name the functions of epithelial tissue. Which type of epithelial tissue is found in areas that need protection? h. Know how to identify simple squamous epithelium, simple cuboidal epithelium, simple columnar…Describe the difference between the rate of diffusion seen for sodium and urea. Select one: 1/Urea diffused faster because it is smaller than sodium. 2/Urea diffused more slowly because it is larger than sodium. 3/Urea diffused faster because it is larger than sodium. 4/Urea diffused more slowly because it is smaller than sodium.
- For each scenario, choose which boundary condition would be appropriate. Consider and list what assumptions you might be making. 1.The solute of interest is diffusing towards the cell membrane, where it is binding to surface receptors. 2.Sugar is diffusing from the surface of a dissolving sugar cube. 3.Blood is flowing over an oxygen transport membrane in a blood oxygenator. 4.Nutrients are diffusing away from the epithelium in a capillary bed into the tissue. Describe the boundary where diffusion of solute from one capillary meets that of another if you assume regular spacing of capillaries.Beans the 21kg Pit Bull needs to be put on IV fluids STAT!

Then you must write your response in complete sentences, thoroughly explaining and justifying your arrows. a. Ouch! Sore throat! It is so swollen that it is sore and it is difficult to swallow. And you have an oral presentation today. Better gargle with salt water to reduce the swelling! Explain why this age old technique really works, by using the concept of osmosis.The left beaker contains 9mM NaCl and 9mM glucose solution.The right beaker contains distilled water.The molecular weight of NaCl is 58.44 g/mol.
