QUES: Bacteria exhibit an extremely wide variety of metabolic types. The distribution of metabolic traits within a group of bacteria has traditionally been used to define their taxonomy, but these traits often do not correspond with modern genetic classifications. Bacterial metabolism is classified into nutritional groups on the basis of three major criteria: the kind of energy used for growth, the source of carbon, and the electron donors used for growth. An additional criterion of respiratory microorganisms are the electron acceptors used for aerobic or anaerobic respiration.
How is bacterial metabolism determined?

ANS: nutritional groups

QUES: While it is undisputed that early humans were hunters, the importance of this for the emergence of the Homo genus from the earlier Australopithecines, including the production of stone tools and eventually the control of fire, are emphasised in the hunting hypothesis and de-emphasised in scenarios that stress omnivory and social interaction, including mating behaviour, as essential in the emergence of human behavioural modernity. With the establishment of language, culture, and religion, hunting became a theme of stories and myths, as well as rituals such as dance and animal sacrifice.
