- what factors affect the rate of diffusion and how can these be tested? pls do cite references so that I can check them tooFor the following scenario you must draw the situation depicted, indicate which solution is hypertonic, hypotonic or isotonic (as applicable), and then show with arrows which way water will move. 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.for the following scenario, DRAW the situation depicted, INDICATE which solution is hypertonic, hypotonic or isotonic (if applicable), and then show with ARROWS which way water will move. then 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
- What will happen if the concentration gradient is high inside the cell and low outside the cell? Explain why the image is applicable in this process.Using appropriate examples, distinguish between passivetransport and facilitated diffusion.The diagram below represents the process of diffusion through the cell membrane.Identify the condition of the membrane as permeable, semipermeable ornonpermeable. Explain how the condition of the cell membrane affects the process ofdiffusion. Remember to include the concentration gradient.
- Two to three drops of mouse blood samples were placed in three different vials containing 0.07 M NaCl,0.15 M NaCl, and 0.30 M NaCl. A drop from each of the three vials were obtained and put on a slide forobservation under HPO. The effects of the different osmotic concentrations on the cells are shown in figures in your worksheets. Label the cell membrane for each figure. Give a short description (size and cell shape) for each of the RBC samples on the space provided in your worksheet. Compare their appearances with RBCs in the blood smear. Use the following guide questions in providing descriptions for each item. Which preparation has cells that look similar as those in the blood smear? What does this indicate about the movement of water in the cells? In which solution do the cells appear differently from the normal RBCs? What part of the cell could have possibly controlled such movement of water? What is its property that allowed this movement?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.
