In order to determine how cells maintain homeostasis in different environments, you place an animal cell with a 3% salt concentration into a beaker containing water with a 3% salt concentration and observe its size and measure its mass over time
☺
А
Which conclusion MOST LIKELY explains how the cell responds to its environment over time?
Water moves into the cell so that the internal and external solutions will be isotonic,
B Water moves out of the cell so that the cell will reach equilibrium with its environment
С There is no movement of water because the internal and external solutions are at equilibrium
c
D
Water moves into and out of the cell at the same rate since the cell is isotonic to its environment

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
