select one:
a. many rows of teeth
b. claspers
c. longer dorsal fin

in \finding nemo\, it sounds as if,when the jellyfish stings, the victim is getting an electrical shock.
what is actually happening?

select one:
a. they are getting an electrical shock
b. the nematocysts are injecting them with venom
c. the jellyfish are warning them that they are poisonous

Explanation:

1. For the shark question: Male sharks have specialized reproductive structures called claspers, which are used for internal fertilization. Many rows of teeth and dorsal fins are not unique to male sharks.
2. For the jellyfish question: Jellyfish stings occur when their stinging cells (nematocysts) inject venom into the victim; they do not deliver electrical shocks, nor is the sting a simple warning.

Answer:

1. b. claspers
2. b. The nematocysts are injecting them with venom
