What is the concentration of material in a cell that affects the fluid volume and pressure within the cell?
Tonicity
Why is concentration gradient important to biological systems?
It affects your learning level and it could ruin your future?
What is the independent variable between temperature and enzyme activity?
To find out how enzyme concentration affects the activity of the enzyme you must:vary the concentration of the enzyme, by preparing different concentrations (keeping the volume of solution the same)keep the temperature, substrate concentration and pH constantmeasure the activity of the enzyme at each concentrationHow the enzyme activity is measured will depend on the specific enzyme involved.You need to have plenty of substrate (excess substrate) so it doesn't run out during the experiment.In this type of experiment, the enzyme activity is the dependent variable, the temperature, pH and substrate concentration are control variables and the enzyme concentration is the independent variable.
What is happens when cells start to swell up with water?
Cells swell up in water because they are not isotonic to the solution they are residing in and therefore at equilibrium. For instance the cells in your body become dehydrated when water rushes out of the cell because the concentration is less on the outside (this is the concentration gradient). Solutes move from high to low concentration. Now since the cells are swelling up with water it is because water has rushed into the cell because the concentration was higher on the outside of the cell so it s said that the solution is hypertonic to the cell. In the case of water rushing out it is said that the solution is hypotonic. In addition it is important to know that this affects animal and plant cells differently. Refer to the link in the "related link" section. ________ Also, one should note that when a cell becomes too full of water, it explodes.
What does the physical change affects?
physical change involves viscosity, conductivity, melting point, boiling point, density, malleability and hardness.
What kind of mathematical relationship exists between conductivity and concentration?
The initial concentration affects the conductivity of a solution in a sense that the greater the initial concentration,the greater the conductivity.increase in concentration means presence of more free moving ions in the solution.but this can only occur in the initial concentration because,after the initial concentration,an increase in concentration will mean that there are now more ions present in the solution but the same volume,hence the ions wouldn't be able to move freely an in the initial concentration,hence the conductivity would then decrease since they can't move freely now.
What are the two main effect of allowing the NaOH solution to remain in contact with the air?
It will absorb carbon dioxide in the air, which affects its accurate concentration.
What are the factors that effects the conductivity of pencil lead?
The percentage amount of graphite used affects the conductivity of pencil "lead". More the amount, lesser is its resistivity and greater the conductivity.
What would the effect be of Nitrate ion in a solution on the color emission?
The nitrate ion concentration affects an equilibrium, because it does this, it makes a more colorful ion change that is concentrated.
Is a dilute solution weak?
It does not matter whether or not HCl is dilute because either way it's a strong acid. Strong and weak are based on its percentage of ionization whereas diluting affects the concentration of the ions. A dilute solution of HCl is not weak.
What affects both the rate of solution and the solubility of a solid in a liquid?
Temperature affects both the rate of solution and the solubility of a solid in a liquid
Why does concentration matter?
Chemically, concentration affects the rate of chemical reaction.When you study if you are not concentrated, you will not remember as much.
What affects osmosis?
osmosis is affected by the concentration gradient the lower the concentration gradient the faster the speed of osmosis
What affects the rate of diffusions?
Temperature, Concentration and size of molecules :)
Is it true that a low concentration of a chemical slows reaction rate?
I would point your studies towards collision theory. It's not that a low concentration necessarily slows down a reaction, but that a low concentration will have a slower reaction rate than a higher concentration of reactants. A lower concentration means a lower number of reactants in solution, meaning it is less likely for the reactants to collide and create products. With a lot of reactants, it is much more likely for collisions to occur.
How does ADH affect the concentration of potassium in urine?
Affects the concentration of potassium in the urine by controlling the amount of water in the urine.
How does gradient affect diffusion?
A concentration gradient is a difference in concentration across a space. It affects diffusion and osmosis because both of these passive transports move down their concentration gradients, or from an area of high concentration to low concentration.
