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.

How do the presence/loss, form, and function of the radula differ within members of the Classes Bivalvia, Polyplacophora, and Cephalopoda (using the squid as a representative)? B) How does this relate to the animals’ natural histories?

To brachiate is to O move around suspended from branches like a Siamang to leap from tree to tree like a lemur O walk on all fours on the tops of branches like a monkey O to walk on two feet like a hominin O to knuckle walk like a chimp

Which is the best possible hypothesis for explaining changes in cortical robusticity over time? a.) The decrease in cortical robusticity associated with the appearance of modern humans was rapid and dramatic and resulted in more lightly constructed skeletons. b.) The increase in cortical robusticity associated with the appearance of modern humans was gradual and resulted in larger brain size coupled with a greater ability to deal with predators l. c.) The decrease in cortical robusticity associated with the appearance of archaic Homo sapiens is a part of a long term trend beginning with australopithecines and ending with modern Homo sapiens. d.) None if these statements are an appropriate hypothesis for changes seen in cortical robusticity.
