Homo species have differences in brachial index, face and teeth size as compared with australopithecines.
Explanation:
Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.
Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
Lions have many other sources of prey so they would most likely still be alive. If we are excluding the existence of other animals, then lions would decrease in population after fourteen days (longest they can go without food).
The proteins whose R groups ionize at different pHs to obtain either a positive or negative charge are hydrophilic and due to this, they are attracted to the water molecules.
The R groups of hydrophilic proteins contain either acidic or basic amino acids.
The hydrophobic proteins are repelled by water and their R group consists of nonpolar amino acids.
When the proteins form a fist like structure, their hydrophobic R groups are hidden inside the fist whereas the hydrophilic R groups face out as it allows the hydrophilic groups to interact with the water molecules in the environment and thus, the protein obtains a stable structure.
