Match each idea about evolution to the person or group where it originated from the drop-down menu. All living things share a co
mmon ancestor. More offspring are born in a population than can survive. All living things are related and change over time. Acquired traits can be inherited. Change is driven by competition and sexual selection. Organisms strive for perfection.
The myelin sheath covers most of the axon. It is important because it helps to protect the axon and speed up the neuron firing process by decreasing the amount of time in the axon.
Glaciers are massive bodies of ice that move across the surface of the Earth like rivers. As glaciers move they change the surface of the Earth by wearing away loose rocks and soil and depositing them somewhere else.
Polychaetes is any of the diverse, mostly marine segmented worms of the annelid class Polychaeta, characterized by having most segments with one pair of lateral, fleshy, lobe like appendages called parapodia, with numerous bristles projecting from them
Polychaetes have true segments and anterior to the true segments lie the prostomium and peristomium
This head region of two segments typically contains two pairs of eyes, three antennae, several tentacles, a pair of palps, and the mouth
Polychaeta is divided into Errantia and Sedentaria for convenience
Errantia (scaleworms, sea mice):A subclass of polychaete worms which have a large number of body segments, those of the head and posterior differing from the rest,the mouth often has several paired jaws
Most are vagile predators, others adopt a burrowing mode of life and are first recorded from the Cambrian
Sedentaria (bamboo worms, coneworms):A subclass of entirely marine worms in which the body segments and parapodia differ along the length of an individual,all Sedentaria are burrowers or tube-dwellers and are first recorded from the Ordovician
