You work hard to pedal your bicycle up a steep hill. you rest when you get to the top, then you let your bicycle roll quickly down the other side of the hill. you converted energy into energy, then you converted it back into energy.

Kinetic, potential and kinetic.

Explanation:

Energy helps to do any form of work. Energy can not be created and can not be destroyed. The energy are inter convertible with each other and no energy is lost during this process.

Two main types of energy are potential energy and kinetic energy. Potential energy is present in rest objects whereas kinetic energy is possessed in moving objects. On pedaling a bicycle kinetic energy is used. Dying rest this energy is converted into potential energy and further on rolling of the bicycle requires kinetic energy.

Thus, the answer is kinetic, potential and kinetic.

b - the respond is innate and varies over time.

good luck!

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
