The history of three major discoveries that led to our current understanding of hominid evolution are as follows.
Explanation:
Raymond Dart a South African anatomist, discovered a skull of a young hominoid with a brain case and facial structure similar to an ape. He classified the organism as a new primate species. Australopithecus Africans which means Southern Ape from Africa.
An American Paleoanthropologist, Donald Johanson, Discovered the complete australopithecine skeletons that he called "lucy". The size of the braincase suggests that their brains had a small, apelike volume and not a larger human volume.
In 1964, anthropologists Louis and Mary Leakey described skull portions of another type of hominid in Tanzania. Leakey classified the hominid with modern humans in the genus Homo. Because stone tools were found near the fossil skull and named Homo Habilis means "handy human".
Cell,tissue,organ,and organ systems
Answer:
<h2>A. Temperature x Entropy (TS)- The total unusable energy of a system </h2><h2>B. Free energy (G) - The total usable energy of a system</h2><h2>C. Entropy (S) - The disorder of a system</h2><h2>D. Enthalpy (H) - The total energy of a system</h2>
Explanation:
<u>The free energy</u> of the thermodynamic system is such a type of energy that is present or available to do work. So it can be called as total usable energy of the system.
<u>Entropy </u>is a thermodynamic quantity that explains about the disorder or the randomness of the system. As the temperature increases, the entropy of the system also increases.
<u>Enthalpy</u> is a thermodynamic quantity that explains the change in the internal energy so consider the total energy of the system.
