What is the best description of osmosis?
Osmosis is a proces of transfer of a diluted solution in the zone of a more concentrated solution through a semi-permeable membrane.
What is The process of adding a known amount of solution of known concentration to determine the concentration of another solution is called?
titration is the best method to determine the unknown concentration of the unknown. if ur known is a solid then you would have to used distilled water to ensure it is submerged before you titrate.
What best describes passive transport?
it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration
How do you find the concentration of potato cells immersed in salt solutions?
You would have to use a spectrophotometer to measure the absorbance of your unknown solution. But first, you need to make several solutions with known concentrations. Measure the absorbance of the known concentrations and plot them on an X and Y axis where X equals concentration and Y equals absorbance. Do a best-fit line for your data. Measure the absorbance of your unknown solution. Find this value on your Y-axis and find out where this value intersects with your line of best fit. The X value at the intersection is your concentration of potato cells. By the way, make sure you use the same wavelength throughout the experiment.
What will happen to decalcified eggs when placed into a hypertonic solution?
This is answered in dot point form because this is the best way to answer your questions in VCE biology -A decalcified egg that is placed in a hypertonic solution will mean that the solute concentration outside of the egg is higher than the solute concentration in the egg cells -This means that due to the solute not being able to move through the semi-permeable membrane, osmosis will take place -Water molecules will move out of the egg to equalize the concentration of the solute outside of the cells and the solute concentration within the cells -Therefore, this will cause a decrease in the mass of the decalcified egg (the more hypertonic a solution is that the decalcified egg is placed into, the greater the percentage of mass loss there will be due to the increase in osmosis) Hope this helped ^-^
What is the best description for a solution with a hydroxide ion concentration of 1x10 4 M?
basic
What is the best description for a solution with a hydroxide-ion concentration of 1x10-4 M?
Assuming that by M you mean moles per liter, you have described a solution with a pH of 10, which is strongly alkaline.
Best description of passive transport?
It moves materials from areas of high concentration to areas with low concentration. A+LS

What type of solution will cause water to move into a cell?
The terms associated with this phenomenon can be quite difficult to get the grasp of for some reason or another to all students. The best way I can describe this is by starting with the solution. By definition of a solution you have a solute and a solvent. The solute is the substance with the lesser concentration. ( e.g. if you have a solution of Salt Water The NaCl (table salt) is dissolved into the H2O( water) since the Salt is being dissolved it is the solute. If you have 2 solutions of salt water Solution A : 10% salt; 90% Water Solution B : 30% salt and 70% water. The two solutions are obiviouslty not equal in proprtion (if they were they would be Isotonic [ equal concentration amounts of water in both solutions]) A Hypertonic Solution Means that it has a higher concentration of solute then the solution in comparison. in this case the solution B would be hypertonic to Solution A. This because the Solute concentration is higher in B than A. Solution B is the hypotonic to solution A because it has a lower concentration of solute. Osmosis is the diffusion of water across a membrane from an area of higher concentration to an area of lower concentration so since Solution B has a lower concentration of water Solution A will pass water into it going from hypotonic to hypertonic.
What is the strength of an acidic solution?
It depends on the concentration of H+ ions in the solution. The more H+, the stronger it is. The best way to determine this is by its pH level, where a lower level means a stronger acid.
