Answer:
The lizards from Iron Cay.
Explanation:
After several generations, they measured the leg length of 10 lizards from each site. <em>The lizards from Iron Cay</em> had longer legs on average. These lizards are trunk-ground anoles, which have long legs adapted to both perch large trees and walk on the ground. But due to evolution, the lizards in the experimental island had shorter legs because longer legs were no needed there.
Answer:
Conservation of mechanical energy
Explanation:
Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system in the absence of dissipative forces (e.g. friction, air resistance), remains constant.
In the absence of air resistance, the mechanical energy of an object moving through the air in the Earth's gravitational field, remains constant (is conserved) while the opposite is the case when there is air resistance involved.
