Dr. bad has developed a way to damage the atp-binding cassette transporter (abc transporter) on a cell. the cell's abc transporter can no longer bind and use atp when it's transporting substances. which of the following statements best describes how this damage would effect the transport of substances in the affected cell? (choice a) substances at a low concentration outside the cell would be more rapidly transported into the cell, where there is a high concentration. (choice b) substances at a high concentration outside the cell would not be transported into the cell, where there is a low concentration. (choice c) equilibrium would be established between all substances inside and outside of the cell. (choice d) substances at a low concentration outside the cell would not be transported into the cell, where there is a high concentration.

Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. a physical change doesn’t break the bonds between atoms of a substance or form new ones. compounds can be broken down by a chemical change. a chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. what simple substance would a compound break into? the basic elements that make it up! for example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. which of the following is an example of a chemical change? a separating water into different glasses b breaking frozen ice cubes with a hammer c running an electric current through water d boiling water to evaporate it on a stove
