45.  Base your answers to questions 45 through 48 on the passage below and on your knowl- edge of biology. Sudden Death from a Marine Predator Members of the Conidae family (cone snails) have been collected for centuries for their beautiful and elaborately detailed shells. Cone snails are marine mollusks found in reef environments throughout the world. Cone snails feed on organisms such as fish, worms, and other mollusks. They are very slow moving but capture their prey by paralyzing them using venom. The venom contains some of the most deadly neurotoxins known. The neurotoxins work by attaching to receptor molecules on nerves, blocking the transmission of nerve impulses. The neurotoxins are injected into the prey by way of a hollow, spearlike tooth and the effects are usually immediate. One species, a fish-eating cone snail, can paralyze the prey in about two seconds. The venom produced by each species is prey specific. It may contain two or more different types of neurotoxins, each composed of long chains of amino acids. 45 Explain how a neurotoxin present in the venom can paralyze one type of prey but not another.
