Which part of the molecules will face the air when a single layer of phospholipid molecules coats the water in a beaker?
The hydrocarbon tails would face the air because they are hydrophobic. The heads of the phospholipids would touch the water.
Why does diffusion eventually result in equilibrium?
I will use the sugar cube example. Equilibrium is established as a result of diffusion. For example, consider placing a sugar cube into a beaker of water. As the sugar cube dissolves, the sugar molecules diffuse throughout the beaker When the beaker is left undisturbed, the concentration of the sugar molecules will eventually remain the same throughout the beaker. Thus, equilibrium is established due to the same concentration of the sugar molecules throughout the beaker.
If a beaker contains glucose and is permeable to glucose what will happen to the glucose?
If a beaker containing glucose is permeable to glucose, then the glucose will go through the beaker.
Why drop of ink can spread in a beaker without stirring?
This is called diffusion. If you just leave the ink in the beaker for a while, it will eventually spread out around the beaker and all of the water will have color. For example: This is just like a restaurant, there is non-smoking half of the restaurant and there is a smoking half. The smoke will eventually spread out front he smoking corner to the non-smoking corner. Another example: If you pee in the pool, the pee will eventually spread out through the pool.
What will happen if a membrane sac filled with large molecules of oil is suspended in a beaker of water?
If a membrane-bound sac filled with large molecules of oil is suspended in a beaker of water, water will start to enter the sac. The sac will then swell.

What happens to acetone molecules when you add heat to a breaker of liquid acetone?
Acetone molecules evaporate when you add heat to a beaker of liquid acetone.
What happens to the water molecules in a beaker as the water that is heated from 10 c to 90c?
The water molecules would speed up, but not to the point of boiling.
When you sit a beaker of hot water on a table what happens to the motion of the molecules that make up the table?
They vibrate faster
Beaker A contains water at a temperature of 15 degrees C beaker B contains water at a temperature of 37 degrees C Which beaker contains water molecules that have greater kinetic energy and why?
Beaker A: 15 C Beaker B: 37 C Beaker B contains water molecules that have the greater kinetic energy (on average). Since beaker B is at a higher temperature than beaker A, the water molecules must be moving faster in beaker B than in beaker A (on average). If heat is being applied to the beakers, then the increased amount of heat applied to beaker B is greater, and the heat will cause the water molecules in beaker B to move faster than the water molecules in beaker A (on average). Kinetic energy = (1/2) (mass) (velocity)^2 Since the velocity of the a water molecule in beaker B is on average greater than the velocity of an average water molecule in beaker A, the water in beaker B has a higher kinetic energy.
If the membrane in a beaker were impermeable would the concentration of salt parts on either side of the mnrame change?
If the membrane in a beaker were impermeable the concentration of salt parts on either side will not change
Remove the drop suspended from a pipet tip by.?
by touching it to the wall of the waste beaker
How do small molecules pass through the cell membrane?
There are three types of transport for molecules across the cell membrane. 1 - Diffusion - Molecules move from an area of high concentration to an area of low concentration 2 - Osmosis - same idea as diffusion, but refers to the movement of WATER across a selectively permeable membrane. How can you change water concentration? Add a solute. If you have 2 250 ml beakers, connected and divided by a selectively permeable membrane, and one beaker contains a salt solution, the salt solution is "hypotonic" (hypo- less, tonic - water) to the water filled beaker. One will see a migration of water into the salt solution beaker. BOTH diffusion and osmosis rely on concentration gradients to perform their jobs. They always want "equilibrium" between both sides of the membrane. 3 - Active transport - Proteins embedded in the cell membrane move large molecules through the cell membrane or AGAINST the concentration gradient. The size one is obvious; If it's really big, it won't permeate the membrane. As for the concentration gradient, this means that it moves a molecule INTO the area with and already HIGHER concentration. If this happens with say... H+ molecules, it creates a potential difference - ie - Voltage across the membrane. Cellular respiration counts on this process to create ATP/Energy for the cell.
What happens when you fill a beaker of soil with water until the beaker is almost full?
You get a heavy beaker full of mud.
Description of osmosis?
osmosis means the movement of water from a high concentration gradient to a low concentration gradient, through a SEMI-permable membrane, osmosis is 'complete' whene both sides are in they state of equalibrium this means when the water molecules are evenly spread out. e.g. a potato clyinder in a water beaker, the water particles in the potato is greater than in the beaker of water, and so as the definition says '...from a high to low concentration...' the water molecules transferr from the potato to the beaker of water. If you don't get it ur dumb
Are there more water vapor molecules above a beaker of water at a room temperature or a beaker of water at its boiling point?
boiling point
