Many kinds of molecules need to be transported across plasma membranes. However, the mechanism of transport depends on the properties of the molecules being transported. Compare mechanisms for moving 1) small, nonpolar molecules and 2) small, charged or polar molecules across a plasma membrane. Explain why these molecules must be transported in these ways due to their properties

The sketch shows a rynchosaur, an extinct animal that is known only from fossils. there has been much debate about the classification of these creatures. some scientists suggest that they belong with primitive amphibians, and some think they are related to snakes and lizards.the data equally support both cases. which statement best explains how to draw a cladogram that includes the rynchosaur? draw the cladogram for amphibians. draw the cladogram for reptiles. draw two cladograms, both showing the traits, and leave it as a hypothesis. draw two cladograms, both showing the traits, and have scientists vote
