Water may dissolve many compounds because of its:

Use this diagramme to answer #19.

1

The molecule shown in the illustration above is passing through the transport protein from an area of high concentration to an area of low concentration. This process is called:

Use this diagramme to answer #20.

If hypotonic cells are placed in a highly concentrated sugar solution, water will:You may use the whiteboard space below this question to draw it out.

Use this space if you would like to draw or visualise the cell and its
environment to help you answer #21. This space is NOT graded.

Use this diagramme to answer #22.

Draw a single phospholipid molecule and label the following: (1) head, (2) tail, (3) hydrophobic end, and (4) hydrophilic ends.

8

Label the cell membrane below using the following terms: (1) phospholipid, (2) transport protein, (3) cholesterol, (4) hydrophobic region, (5) hydrophilic region, (6) head, (7) tail, (8) polar, (9) non-polar Be VERY specific - circle items if necessary to make it very clear what you are labeling!
