College General Biology 1 Discuss Osmosis. Osmosis in animal cells and Osmosis in plant cells. What are the similarities and differences? Discuss osmosis in your own words. Do not copy and paste your answer from a website or a book and explain things in some detail and length. Explain your explanation in several paragraphs and in detail. Go into some depth and explain the similarities and differences of osmosis in animal cell and plant cells. In other words, your answer has to cover all the basics and should be more than just a Britannica encyclopedia or Khan Academy  or LumenLearning or Wikipedia article on the topic. Base your response on an original response.

1- How would you describe the Lenski experiment and its significance? Could you provide a concise explanation of the experiment in no more than half a page? Afterward, please create a visual representation of the experiment using your own drawings. You can utilize digital applications, such as Paint or tablet-based drawing tools, or hand-draw the diagram and capture it in a photograph. The visual representation should be schematic in nature, demonstrating the key components of the experiment. (you can draw the plates, bacteria etc. I need an explanative image that created by YOU. Any screenshot is not allowed. You can use paint, any application on your tablets or you can draw it by hand and take a picture. You need to create a schematic diagram.

You are viewing two samples of mammalian red blood cells (erythrocytes) under a microscope. One first sample is made up of cells with a typical round shape. Most of the cells in the second sample had burst open. •Describe the properties of the solution that was used to prepare the second sample. • Identify one type of solute that can move through simple diffusion and does not affect osmotic pressure or require a membrane protein to cross a plasma membrane.

Scientists let rice blast fungal infection cells attach to and attempt to penetrate six different polymer sheets for different lengths of time and in varying extracellular osmotic pressures (Figure 22.9). As the number of the sheet increases so does its hardness. Which of the following makes the most sense based on the data? 100- 60 40- 20- 192 incubation time (hr) 72 96 240 100- 80- 60- 40- 20- b-Oo 8 10 12 extracellular osmotic pressure, MPa Figure 22.9 Penetration as a function of incubation time (A) and extracellular osmotic pressure (B). Numbers 1 to 6 in both panels indicate the substrate, with lower numbers being softer substrates. Percent penetration goes down over time and as substrate hardness increases. If penetration of a substrate occurs at a particular external pressure, this indicates that internal pressure is high enough to allow penetration of the particular substrate. Harder substrates are more easily penetrated when extracellular osmotic pressures are low. The…

EXPERIMENT : CRYOPRESERVATION OF CULTURED CELL LINES Questions What are differences between adherent and suspension cells. After 3 days of cryopreservation, the cell morphology was observed under the microscope.The total cell concentration is reduced into half of the number after cryopreservation. What are reasons for decreasing in cell concentration.Justify your answer.

determine if osmosis or simple diffusion          A crystal of blue copper sulfate is placed in a test tube of water.  The next day, the solid is gone, but the water is evenly colored.     A fresh potato is peeled, weighed, and soaked in a strong salt solution.  The next day, it is discovered that the potato has lost a significant amount of mass.     A perfume bottle is opened, and soon the odor can be sensed in all parts of the room.     Garden grass wilts after being exposed to dry chemical fertilizer.     Plant seeds soaked in water swell and become several times as large as before soaking.     A sugar cube is dropped into a cup of hot water, and without being stirred, all of the liquid becomes sweet tasting.

The average concentration of salt in seawater is about 3.5 percent and the average concen- tration of salt in the human cellular environment is about 0.9 percent. Drinking seawater can be fatally harmful and is highly discouraged even in the most severe cases of dehydration. Which of the following provides the most likely cause for this fact? A B с D The increase in salt concentration in the extracellular environment will increase the per- meability of the cell membrane. The increase in salt concentration in the extracellular environment will cause the move- ment of water into the cell. The increase in salt concentration in the extracellular environment will cause the move- ment of water out of the cell. The increase in salt concentration in the extracellular environment will decrease the per- meability of the cell membrane.
