Respiration is a process where many chemical bonds inside the body break and release energy. this energy is used to perform various activities such as moving muscles. explain the energy transformation in this process. a. chemical energy from broken bonds is transformed into mechanical energy for muscles. b. mechanical energy from broken bonds is transformed into chemical energy for muscles. c. mechanical energy from broken bonds is transformed into electrical energy for muscles. d. heat energy from broken bonds is transformed into electrical energy for muscles.

A. Chemical energy from broken bonds is transformed into mechanical energy for muscles.

Explanation:

Chemical energy is the energy stored in the bonds of molecules.

Mechanical energy is the energy possessed by a body by virtue of its position and motion.

According to law of conservation of energy, energy remains conserved. It only transforms from one form to another.

When we respire, we inhale oxygen which is used in oxidation of food we eat and thus the chemical energy stored in the bonds of food converts to mechanical energy which is used to perform various activities such as moving muscles.

Thus the energy transformation will be chemical energy from broken bonds is transformed into mechanical energy for muscles.

A

Explanation:

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.
