Explanation:
Semipermeable membranes in cells are usually made up of phospholipids. Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.
Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.
Reverse osmosis, uses the process of osmosis, along with high pressure; it forces water molecules across a porous membrane. Only water passes through, as the larger salt, other solute molecules and microorganisms cannot fit through the pores of the semipermeable membrane. Additionally, applying pressure alters the pressure potential of the system and thus the water potential by creating a steep gradient; water molecules move from areas of high water potential to areas of lower water potential... The molecules cross the membrane, and the purified water is separated.
<em>recall: water potential= pressure potential + solute potential</em>

Answer:
Peptic ulcer are the open sores which form inside the lining of the stomach and in the upper portion of the small intestine.
The stomach pain is most common symptom of this disease. It is not caused by spicy food and stress.
It is caused by the infection of bacterium Helicobacter pylori and it cam also be caused due to long term intake of the non steroidal anti inflammatory drug.
The risk is person should not take spicy food once he is detected by this disease and should discontinue the drugs causing this disease.
<u>20 markers will cost Ms. Lasater $41.25.</u>
<h3>Proportion</h3>
This is a topic in mathematics that treats a value as a part of the entire data.
In the question given, we were asked to find the cost of 20 markers.
Data given;
- 8 markers is sold for $16.50
To solve this problem, we can either find the cost of one markers and multiply the value by 20 to get the cost of 20 or simply set an equation to find the cost of 20 markers.
Let the cost of 20 markers be represented by x
cross multiply both sides and solve for x
20 markers will cost $41.25
From the calculation above, we have the follow data
- 8 markers costs $16.50
- 20 markers cost $41.25
