A student conducted an experiment to determine the molar concentration of solutes in chicken eggs. Eggs were soaked in vinegar t
o remove the shells the eggs were then placed in sucrose solutions of different concentrations. The data is shown in the table below. Sucrose
Concentration Inltial Mass Final Mass Change in Marss Percent Change
(Molar) (g) (g) (g) in Mass
0 78.50 81.73 3.23 4.11
0.5 79.11 77.50 -1.61 -2.04
1.0 80.75 75.14 -5.61 -7.12
2.0 76.99 66.64 -10.35 -13,44
b. Using the data, determine the molar concentration of chicken egg cytoplasm and justify your answer.
c. Movement of water and nutrients is critical for the survival of plants. Using the concept of water potential, explain the role of positive and negative pressure in the transport of water and nutrients throughout a vascular plant.
An efficient way to search for and insert a value in a cell when the desired value is stored elsewhere in the worksheet or even in a different workbook is by using lookup functions.
Explanation:
Lookup function is the built in function of excel that helps in returning the certain value form specific row or column.
When the value is stored in the worksheet we can easily insert that desired value in the cell by the use of lookup functions.
VLOOKUP and HLOOKUP are the lookup unctions that searches the value in column and row respectively.
