Moles are mammals that live underground and eat worms. Moles are adapted to use their sense of smell to locate their food. Which environmental change would MOST LIKELY allow for an increase in the number of
moles born with a better sense of smell?
Less rainfall causes the worms to come closer to the surface so the moles need to have a better sense of
smell to locate the worms.
Less rainfall causes the worms to burrow further underground so the moles need to have a better sense
of smell to locate the worms.
More rainfall makes the soil easier for digging so the moles need to have a better sense of smell to locate
the worms.
More rainfall makes the soil harder for digging so the worms need to have a better sense of smell to
locate the moles.

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
