When studying fossils, you can conclude that life in the past differed greatly from the organisms observed today. Life's history on Earth is incredibly diverse compared to the organisms that scientists currently study. What factors led to some of the mass extinctions that occurred in the past?

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
