99999393 3385 338 wikimedia commons Some embryos share many similarities and are difficult to tell apart, while others are slightly easier. What can you conclude about the similarities and differences between the embryos of different species? Select one: a. The more closely related species show differences from the earlier stages. b. The more distantly related species share similarities until the later stages. c. The more closely related species share similarities until the later stages. d. The more distantly related species show differences in only the later stages.

According to "The Complex Evolution of Homo sapiens", where were the earliest fossils that are potentially Homo sapiens found? How old are they?    A.Morocco - 3 million years old B.Kenya - 300,000 years old C.Morocco - 300,000 years old D.Tibet - 300,000 years old     A.Ivory rings B.Jewelry from stone and marble C.Needles made from bone D.Both A and B E.A, B and C

One hypothesis for the Cambrian explosion was an increase in predator-prey relationships. It is thought that the resulting co-evolution of predator and prey may have been a factor in the rapid speciation of animals seen during this time. What findings in the fossil record would most support this? Group of answer choices a. increased incidence of larger-bodied animals b. increased incidence of sessile animals c. decreased incidence of animals with bilateral symmetry d. increased incidence of animals with radial symmetry e. increased incidence of shells, bony plates, spines, and/or claws

Why is it interesting that Homo luzonensis was found on an island?    A. The islands only formed after Homo luzonensis became extinct, so Neanderthals must have put them on the island   B. The islands were a few miles apart, and Homo luzonensis would have needed to either float by grabbing on a tree or make a raft   C. The islands were a few miles apart, and Homo luzonensis clearly had to learn how to fly to get to them   D. The islands were volcanoes when Homo luzonensis was alive, so it's unexpected that they were there

27. Which term describes any ancient remains, impressions, or traces of an organism or traces of its activity that have been preserved in rocks or other mineral deposits in Earth's crust? a. analogous feature b. homologous feature c. mutation d. fossi

Spirochetes are free-living, anaerobic bacteria that contain spiral-shaped cells. Nematodes are roundworms that are incredibly diverse and, as a group, have adapted to survive in all environments. Which of the following statements accurately describes the DNA of both groups? A. The spirochaete genome is smaller than the nematode genome. B. Nematode DNA is circular. C. Spirochete chromosomes are composed of just DNA while nematode chromosomes also include specialized proteins. D. Spirochete DNA is linear.

Question 2U Which is NOT an example of homoplasious characters? A More than one of these. B Bats and birds are both monophyletic groups with wings. Many species of insects, amphibians, and fish have evolved red and yellow warning coloration to advertise their poisonous skin or organs. Sharks and dolphins have fins and fuselage-shaped bodies, despite sharing a distant common ancestor. E) The amniotic egg is a synapomorphy of terrestrial vertebrates, but has been lost in many groups. Do you have additional content? You can add text, images, and files that support your answers.
