concentration (increase in osmolarity) which will cause an increase in water reabsorption (decrease in osmolarity). ADH most important function is to conserve the fluid volume of your body by reducing the amount of water passed out in the urine. When there is a decrease in serum sodium levels (decrease in osmolarity) the ACTH causes the adrenal cortex to release aldosterone‚ thereby increasing sodium reabsorption in the distal convoluted tubules of the kidney (increasing osmolarity). Aldosterone also

the same for potato cores placed in varying concentrations of solutes of NaCl‚ glucose‚ and sucrose. This experiment was designed to test these predictions and compare them to data gathered course wide. We found that the mean water potentials were all within 0.26 bars of each other‚ and that the zero weight change osmolalities were all within 0.035 mols of each other. This supported Van’t Hoff’s predictions that water potentials and osmolalities would be the same. We had to collect potato core samples

______ 1. Background: Potato is a starchy‚ tuberous crop from the perennial “Solanum tuberosum” of the Solanaceae family (also known as the nightshades). It originated from the area of present-day southern Peru and it’s now grown worldwide. Potatoes were first introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world ’s cuisine. It is the world ’s fourth-largest food crop‚ following rice‚ wheat‚ and maize. Wild potato species occur throughout

small particles caused by the bombardment of the particles by millions of water molecule. This movement will continue indefinitely as long as there is water. My prediction for this lab is the solution of the water is hypertonic meaning there is a higher concentration of solutes outside of the cell. To test my prediction my lab partners conducted the Brownian movement.

Determine the mass of the four cylinders. Immerse four cylinders into each of the six beakers or cups. Let stand overnight. After time is up‚ remove the cores from the sucrose solutions and mass them. Record all data in its appropriate table.

do: We will put potato pieces of similar sizes in to test tubes of different concentrations of sucrose solution‚ and measure any changes in mass and length. Affecting Factors: There are a number of factors which can affect our results. We need to keep them all the same‚ and make sure that the only thing that changes is the concentration of the sucrose solution. These factors include: • Starting length of potato • Volume of Sucrose solution • Temperature of potato • Temperature

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and
