The ADP-ATP cycle is critical to producing cell energy. What do you know about this cycle? (More than one answer) 1. On average, 34-36 molecules of ATP are gained through the process of aerobic cellular respiration from
one glucose molecule.

2. When phosphate is added to ADP, free energy from food sources is stored in the phosphate bond,
producing ATP.

3. The hydrolysis of ATP to ADP is reversible.

4. When a phosphate group is removed from ATP by hydrolysis, ADP is produced and energy is stored for
cellular processes.

5. Only aerobic cellular respiration is used to break down glucose into ATP that is usable by the cell.
6. Glycolysis is the first step in both aerobic and anaerobic cellular respiration.

Archeologists have discovered three sites showing conclusive evidence for the mastery of fire in tanzania, from a period slightly after the time that homo habilis was present in africa. these sites clearly were founded by homo erectus, the descendent species of homo habilis that migrated north, out of africa and into asia. homo erectus was known to have mastered fire, from ample evidence at sites in asia. there is no reason to attribute mastery of fire to homo ergaster, the descendent species of homo habilis that remained in africa.which of the following is an assumption on which the argument depends? (a) before their migration, homo erectus occupied african territory as far south as tanzania.(b) the strain of migration provided the selective pressure motivating homo erectus‘ mastery of fire.(c) homo ergaster would not have derived as much benefit from the mastery of fire as did homo erectus.(d) homo ergaster inherited all cultural knowledge from homo habilis, a species that did not have mastery of fire.(e) homo ergaster did not occupy regions as far south as tanzania until well after the time of these three sites.
