no
can charged particles go through lipids
no
in which direction does active transport flow ( concentration gradient) ?
low to high
in which direction does diffusion flow ( concentration gradient )
high to low
what is solute
solute is what is dissolved
what is solvent
solvent is what dissolves
what is solution
is a mixture of the solvent and the solute
what is hypotonic
a solution with a lower concentration of solute
what is hypertonic
a solution with a higher concentration solute
what is isotonic
a solution with a balance of both solvent and solute
what are 3 substances dissolved in the plasma of blood
O2, CO2, glucose, cholesterol
what does a diluted solute ( osmosis ) cause the water to become
concentrated
what does a concentrated solute ( osmosis ) cause the water to become
diluted
in osmosis water will move where the ____ concentration is higher
solute
what is the Biuret solution
Biuret test is a test for protein its colour is blue and when a solution tests positive for protein then it will turn purple if the solution does not contain protein then it will stay blue
what is the Iodine test for starch
This is a test for starch it is yellow if what is being tested is positive for starch then it will turn blue-black if it remains yellow the same then it does not contain any starch
what is the Benedict’s solution
Benedict’s solution is a blue solution that tests for sugars if the solution contains sugar it will turn orange or red if it doesn’t contain sugar then it will remain blue
