A/an solution occurs when the solute concentration outside of the cell is higher than the solute concentration inside the cell most cells have an electrical potential difference of between –40 and millivolts. is a determining force in water movement, and causes water to move from areas of high water concentration to low water concentration. in most cells, there are more molecules inside the cell and more sodium molecules outside the cell. a/an exists when different concentrations of a substance exist on either side of a membrane. respond to the following based on your reading. describe the difference between a chemical and an electrical gradient. what's an electrochemical gradient? do you think an electrochemical gradient can have conflicting component gradients? (that is, a chemical gradient directing solute flow in one direction, and an electrical gradient directing solute flow in the opposing direction.)

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.
