Homework Answers
D. In blood - the RBC looks normal and there is no loss of morphology of the RBc it shows rounded apperance.
A. In the hypertonic solution - the normal morphology is lost the RBC become shrunken or crenated
B. In the isotonic solution - the morphology of RBC is maintained RBC appear round.
C. In the hypotonic solution - the morphology of RBC is lost and cells become swollen and alomgwith bursted cells can be seen.
( In the hypertonic solution there is a net movement of all the water from the RBC to the surrounding solution which causes shrinking of the cells. In the isotonic solution the net movement of water is maintained which helps in retaining the morphology of the cells. In the hypotonic solution there is net movement of water from the solution into the cell which causes the cell to swell up and eventually burst).

Lab 2A:
Introduction
In this lab, you will be studying osmosis across the membrane of
potato cells. You will create equal-sized pieces of potato and then
place the pieces in solutions with differing concentrations. You
will then, over time, measure any changes that take place in the
size and weight of the potato pieces.
To measure changes in size, you will need either a gram scale
(like a food scale) or a millimetre ruler. It is best if you have...

Let x be a random variable that represents red blood
cell count (RBC) in millions of cells per cubic millimeter of whole
blood. Then x has a distribution that is approximately
normal. For the population of healthy female adults, suppose the
mean of the x distribution is about 4.78. Suppose that a
female patient has taken six laboratory blood tests over the past
several months and that the RBC count data sent to the patient's
doctor are as follows.
