2 Lepus       4 snowshoe

117 Based on its diet, the hare is classified as

1 an herbivore      3 an autotroph
2 a carnivore        4 a decomposer

118 Using one or more complete sentences, state one adaptive advantage

and hop soon after birth.

119 The results of one experiment carried out by a research team would be
considered valid if

1 the experiment had no control setup
2 all the members of the research team came to the same conclusion
3 the experiment had more than one variable
4 the experiment was repeated and the same results were obtained
each time

120 Which paragraph describes the correct procedure for preparing a 
stained wet mount of onion epidermis?  

1. Place a slice of onion epidermis on a slide. Add two drops of water and one drop of stain.
Cover the slice by dropping a cover-slip directly on top of it. Press on the cover-slip to force
air bubbles out. Add one drop of water to one edge of the cover-slip, and add one drop of 
stain to the opposite edge.

2. Add one drop of stain to a piece of onion epidermis. Using forceps, place the epidermis on
a slide. Blot the epidermis with a piece of paper towel to remove the excess stain. Drop a 
cover-slip onto the specimen.

3. Place a piece of onion epidermis on a slide. Add one drop of water. Put one edge of a 
cover-slip in the water drop, then slowly lower the opposite edge to the water. Put one drop 
of stain at one edge of the cover-slip. Put a piece of paper towel at the opposite side of the
cover-slip. Allow the towel to absorb some water so that the stain will move under the 
cover-slip.

4. Add one drop of stain to a slide. Place a piece of onion epidermis on top of the stain. Use
a piece of paper towel to absorb the stain. Drop a cover-slip on the epidermis to flatten it out.
Lift the cover-slip and add a drop of water to the epidermis. Replace the cover-slip.

124 A compound light microscope is represented in the diagram below.

Which microscope part is correctly paired with its function , ?

(1) A - magnifies the image of the specimen
(2) B - used for focusing only when the high-power objective is used
(3) C - provides the field of view with the largest diameter
(4) D - holds the specimen on the stage

125 A diagram of a grasshopper dissection is shown below.

Which statement best describes the location of structure X , ?

1 It is ventral to the nerve cord.
2 It is dorsal to the digestive tract.
3 It is anterior to the crop.
4 It is posterior to the anus.
