Herbivory (plant eating) has evolved repeatedly in insects, typically from meat-eating or detritus-feeding ancestors (detritus is dead organic matter). Moths and butterflies, for example, eat plants, whereas their "sister group" (the insect group to which they are most closely related), the caddisflies, feed on animals,

Four of the following examples provide support for this prediction, but one is irrelevant. Which of examples listed below does not support the claim that species are related? O A. Many dinosaurs and other organisms went extinct following a huge asteroid impact at the end of the Cretaceous. O B. All prokaryotes and eukaryotes use DNA to carry their genetic information. OC. Before synthetic insulin was available, diabetics used injections of purified pig insulin to manage their disease. O D. Ground squirrel species found on the North and South sides of the Grand Canyon are very similar to each other. O E. The endostyle of lancelets (invertebrate chordates) and the thyroid gland of vertebrates develop similarly, and both produce iodinated proteins. «< Question 5 of 120 A Moving to another question will save this response. 11:51 AM 12/16/202 End F10 pgUP F11 PgDn F12 Home PrtScn F8 DII F5 F7 F6 F3 F4 F2 & #3 2$ 7 8 9.…arrow_forward
