How did natural selection most likely result in this evolutionary changeHow did natural selection most likely result in this evolutionary change?

Bright mice were not able to blend into their environment as easily as dark mice, so they did not continue to survive and reproduce.
Bright mice produced fewer offspring than dark mice, so the bright mice became outnumbered within days.
Random changes in the genetics of bright mice produced more dark mice, so the bright mice quickly died off.
Random changes in the genetics of dark mice produced fewer bright mice, so the dark mice took over the population.

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.

Some molecular compounds, such as hcl, ionize completely in solution. for molecular compounds such as h2co3, most molecules do not ionize in solution. which describes the properties of these two solutes? a. hcl and h2co3 have the same effect on the properties of the solution. b. hcl raises the freezing point of water more than h2co3 does. c. hcl raises the boiling point of water more than h2co3 does.
