Australopithecus is an ape that lived in trees, but could walk on two feet. how might fossils from australopithecus provide evidence for evolution? a. australopithecus is a fossil that is used to date other precambrian fossils. b. australopithecus provides evidence of the existence of apes, but not humans. c. australopithecus is a transitional form between apes and humans. d. australopithecus provides evidence that humans existed.

The correct answer is (C) Australopithecus is a transitional form between apes and humans.

Australopithecus had both the features of ape and human. These members have ape like face proportion and human like braincase less than 500 cubic centimeters.  They had strong arm and canine teeth just like humans and their body stood on two legs.These species have been found to survive more than 900,000 years. Their adaptation to live on trees and on land helped them to survive for such a long time.

Thus, all the characters shows that Australopithecus is a transitional form between apes and humans.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
