1.) explain why at the cellular level, plants have more in common with animals that they do with bacteria.
2.) When you flush a toilet, water begins to fill the tank and lift a float attached to a lever. When the water level reaches a certain height, that lever shuts the water valve and prevents the tank from overflowing. What type of regulatory mechanism is at work in the nonliving system?
pleasee help mee
