The amount of kinetic energy depends on the mass and the speed. The kinetic energy of an object is directly proportional to its mass and speed. So, if the mass of a body increases, it’s kinetic energy also increases even if the velocity remains constant. So, yes, Robert’s kinetic energy will be twice as much. Also, think of it this way-since Robert has twice the mass as his sister, he will also need twice the amount of kinetic energy to run in the same velocity as his sister.
Eventually, all of the energy that enters the ecosystem is lost in the form of heat.

b. small population, many mutations
c. small population, few mutations
Small population, many mutations are the combination of characteristics in a population would provide the greatest potential for evolutionary change.
b. small population, many mutations
<u>Explanation:</u>
Stabilizing selection in development is a kind of common choice that supports the normal people in a populace. In little, reproductively detached populaces, extraordinary conditions exist that can create fast changes in quality frequencies absolutely autonomous of transformation and normal determination.
Natural Selection prompts a transformation change when a few people with specific qualities in a populace have higher endurance and regenerative rate than others and give these inheritable hereditary highlights to their posterity. The power of Natural Selection aside, populace size is as yet a factor to be considered.
