As per the second law of thermodynamics , there is an increase in the entropy of an isolated system as the isolated system moves towards thermal equilibrium i.e the maximum entropy state of the system. In other words the entropy of a system always increases and it can never decrease. Thus. a system never yields as much energy as was put in. This increase in entropy happens because the more and more energy is transferred or changed from one form to the other, the more and more energy is wasted and released which then adds to the total entropy of the system.
The correct answer is letter C, in most primates, the inability to move the ear has been replaced by the ability to stand upright on two legs. This is because movement was much of a need to these primates than hunting for food. They needed to be agile to locate specific places where sources of food are abundant.
As many believe after doing an extensive form of research work of years that reptiles are the ancestors of the mammals that we see now. Which means that we mammals evolved from the pre-historic form of reptiles.
Explanation:
Fossils of Thrinaxodon, a species that lived during the Triassic period, have been found in both South Africa and Antarctica. Thrinaxodon had a reptile-like skeleton and laid eggs, but small depressions on the front of its skull suggest it had whiskers and, therefore, fur. Thrinaxodon may have been warm-blooded. The fossils of Thrinaxodon are consistent with the hypothesis that <u>mammals evolved from the pre-historic reptiles.</u>
