For better understanding of the role of each part of the spinal cord, several experiments are performed on a frog. The
following table summarizes the experiments and the results.
Section of dorsal root
Section of vental root
Section of spinal nerve

1-Pose the problem studied.
2-Indicate the role of the dorsal root.
3-Show that the spinal nerve is a mixed nerve.
After several complete sections, there are degeneration in the
roots as shown in the figure below:

Use this dichotomous key for insect identification to identify the insect shown. 1. a. insect has one pair of wings. order diptera b. insect has two pairs of wings. go to #2 2. a. front wings thicker in texture than hind wings go to #3. b. front and hind wings are same texture throughout. go to #4 3. a. front wings are short order dermaptera b. front wings cover entire abdomen order coleoptera 4. a. wings with scale on all parts of their area. order lepidoptera b. wings without scales go to #5. 5. a. hind wings smaller than front wings. order ephemeroptera b. front and hind wings nearly equal in size. order odonata the insect pictured is in the order diptera. ephemeroptera. coleoptera. odonata.
