which statement about mesosaurus fossils and continental drift is most accurate?

the mesosaurus could have evolved on both continents, so the fossils are not evidence for
continental drift.
the mesosaurus fossils are found over too large of an area to provide any information
about continental drift.
the mesosaurus lived in coastal areas so the fossils show that the coastlines have changed
as the continents drifted apart.
the mesosaurus could not swim between the continents in the open ocean, so the fossils
show that the continents must have been together in the past.

Hot air balloons float in the air because of the difference in density between cold and hot air. in this problem, you will estimate the minimum temperature the gas inside the balloon needs to be, for it to take off. to do this, use the following variables and make these assumptions: the combined weight of the pilot basket together with that of the balloon fabric and other equipment is w. the volume of the hot air inside the balloon when it is inflated is v. the absolute temperature of the hot air at the bottom of the balloon is th (where th> tc). the absolute temperature of the cold air outside the balloon is tc and its density is ďc. the balloon is open at the bottom, so that the pressure inside and outside the balloon is the same. as always, treat air as an ideal gas. use g for the magnitude of the acceleration due to gravity.

What overall charge must all compounds have

Achemist has dissolved a certain substance in water. the chemist knows that more of the substance could be dissolved into the water before it stops dissolving. therefore
