Answer 3

Osmoles or osmolarity

Question 4

Answer 4

NaCl, CaCl2, Na2CO3

Question 5

What are examples of non-ionizing molecules?

Answer 5

Sucrose, glucose, urea, glycerol

Question 6

What is an ISO-osmotic solution?

Answer 6

A tissue/cell type that is one in which the H2O is the solution is the same as the H2O in the cell

Question 7

What is the ISO-osmotic for Macmillan cells?

Answer 7

.29 moles of dissolved particles

Question 8

What makes a cell hypotonic?

Answer 8

The dissolved particles is less than the ISO-osmotic.

This will cause the cell to swell.

Question 9

What makes a cell hypertonic?

Answer 9

The dissolved particles is greater that ISO-osmotic

This will cause the cell to shrink
