Although some sharks close their eyes just before they bite,their bites are on target. Researchers have noted that sharksoften misdirect their bites at metal objects and that they canfind batteries buried under sand. This evidence suggests thatsharks keep track of their prey during the split second beforethey bite in the same way that(A) a rattlesnake finds a mouse in its burrow.(B) an insect avoids being stepped on.(C) a star-nosed mole locates its prey in tunnels.(D) a platypus locates its prey in a muddy river.
Bats mostly hunt insects at night. They are able to determine the distance and speed of any prey they are chasing, which has helped them to become excellent nocturnal predators. One potential prey, the tiger moth, has developed two separate methods of evading predation.
First, tiger moths emit a toxin that is distasteful to bats, birds, and most other vertebrate predators. Second, they use an organ called a "tymbal" to create a series of high-pitched clicks that only bats can hear, and which identify the tiger moths as something the bats don't like to eat. Bats who prey on tiger moths discover they don't taste very good, learn to identify tiger moths by their clicks, and avoid eating them. Use this information to answer the questions below.
Question 1: The scenario above describes a distinct evolutionary interaction. What is it?Can you explain?
Question 2: Why is it necessary for the moth to produce both a tymbal click and a toxin? Why not just a toxin? Do you think there are…

A. to allow grooming for social bonding
B. to allow access to foods on outer branches of trees
C. to allow tool making
