1. Consider the integument:
(8)
Name the three types of cells we find in the stratum
basale.
Which of these is a specialized receptor?
Besides sensation, name two other functions of the
integument.
Choose one of these functions, and describe how
specific structures or organization of the integument
help is to perform that function.
2. Explain two reasons why maltose, (a simple sugar made of two glucose molecules) requires a carrier
protein to cross the cell membrane.
(4)
3. Consider red blood cells bathed in plain water:
(4)
Explain what will happen to them.
Explain why that happens.
4. Please list the following compounds in order of fastest to slowest diffusion rate: O2, Xe, H2, Cl2. (3)
5. On a compound microscope, as total magnification increases,
(3)
working distance:
The diameter of the field of view:
and the apparent size of the specimen:
6. Please explain how a negative feedback mechanism operates.
(3)
7. Consider cellular decorations:
(6)
What is the function of microfilaments?
Where in the body would you expect to see cells with
microfilaments?
How does their internal structure differ from cilia
and explain how that helps to explain their function.
8. Please fill in the blank with the correct cellular organelle:
Converting absorbed food energy to ATP
Digesting imported vesicles full of food
Adding proteins to the cell membrane
Manufacturing proteins
Packing and shipping off hormones
(10)
9. You find an unlabelled tissue slide and view it under the light microscope. You see few cells surrounded
by many tightly packed, parallel fibers:
(6)
What sub-type of connective tissue are you
probably looking at?
What does the fiber orientation suggest to you
about its function?
Name two places you would expect to find a
tissue like this.
10. Consider the hair on your arm:
What type of tissue is it?
What type of gland supports and lubricates it?
Name two components of this lubricant.
