C) The Cambrian explosion is evidence for the instantaneous creation of life on Earth. 43) Which section of sea-floor crust should have the thickest layer of overlying sediment, assuming a continuous rate of sediment deposition?D) The Cambrian explosion marks the appearance of filter-feeding animals in the fossil record. A) A B) B C) C D) D E) EThe figure represents a cross section of the sea floor through a mid-ocean rift valley, with alternating patches of black and white indicating sea floor with reversed magnetic polarities.9) If natural selection in a particular environment favored genetic systems that permitted the production of daughter "cells" that were genetically dissimilar from the mother "cells," then one should expect selection for which of the following? polynucleotide polymerase with low mismatch error rates II.polynucleotide polymerases without proofreading capability III. batteries of efficient polynucleotide repair enzymes IV.

B) change the atmosphere from oxidizing to reducing. D) cause iron in ocean water and terrestrial rocks to rust (oxidize). E) Its Hox genes cooperate to bring about sexual maturity at the proper stage of development.30) Bagworm moth caterpillars feed on evergreens and carry a silken case or bag around with them in which they eventually pupate. C) the earliest reptiles could fly, and the feathers of flightless dinosaurs were vestigial flight surfaces. SEE IMAGEThe figure represents a cross section of the sea floor through a mid-ocean rift valley, with alternating patches of black and white indicating sea floor with reversed magnetic polarities.

E) Recent evidence supports the contention that the Cambrian explosion may not have been as "explosive" as was once thought.18) What is thought to be the correct sequence of these events, from earliest to most recent, in the evolution of life on Earth? At the arrow labeled "I" (the rift valley), the igneous rock of the sea floor is so young that it can be accurately dated using carbon-14 dating.

At the arrow labeled "III," however, the igneous rock is about 1 million years old, and potassium-40 dating is typically used to date such rocks.

E) prevent the formation of an ozone layer.16) Which of the following statements provides the strongest evidence that prokaryotes evolved before eukaryotes? B) The meteorites that have struck Earth contain fossils only of prokaryotes. Adult female bagworm moths are larval in appearance; they lack the wings and other structures of the adult male and instead retain the appearance of a caterpillar even though they are sexually mature and can lay eggs within the bag. D) the feathers were plucked from the bodies of other adults to provide nest-building materials. At the arrow labeled "I" (the rift valley), the igneous rock of the sea floor is so young that it can be accurately dated using carbon-14 dating. The figure represents a cross section of the sea floor through a mid-ocean rift valley, with alternating patches of black and white indicating sea floor with reversed magnetic polarities.

C) Laboratory experiments have produced liposomes abiotically. E) The oldest fossilized cells resemble prokaryotes.17) What is true of the Cambrian explosion? E) all fossils with feathers are actually some kind of bird.41) Several scientific laboratories across the globe are involved in research concerning the origin of life on Earth. At the arrow labeled "III," however, the igneous rock is about 1 million years old, and potassium-40 dating is typically used to date such rocks. At the arrow labeled "I" (the rift valley), the igneous rock of the sea floor is so young that it can be accurately dated using carbon-14 dating.
