4. Prepare your own key for the five fish in Figure 3. Use the same format as on page 119. The family names to be used are the numbers 1. 11. III, IV, and V. Your key should correctlyc
use traits that will lead to each fish family. To help you get started, the first statements are
given. Statement 1 divides the five fish into two main groups, based on body shape. Next,
Choose another characteristic that will divide the fish not having a tubelike body into two
groups. Continue to choose characteristics that will separate a group into smaller groups.
Write your key in the space below.

According to your text, should be in the native language of the parents or guardians whenever possible. a. an email b. consent forms c. oral approval d. storybooks loaned out

When a gasoline engine burns gasoline, what type of chemical reaction is occurring?

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
