the two major parts of science is probably life science and technology.
Earth Science
The two part of science question are CAUSE and EFFECT relationship. also exact measurement and calculation.
Mechanics, which has two parts. Statics - Science of bodies at rest. Dynamics - Science of body/ies in motion.
science is divided in two parts .first is based on physics (Pressure, temperature,)and other-one is based on chemicals and elements.
I'd suggest the two major divisions would be that separating the life sciences (botany, biology, anthropology ..) from the 'exact sciences' (physics, chemistry, astronomy, nuclear physics ..).
the two major branches of science are biological science and natural science. these two are divided into many branches.
The two major fields of science are Social Science and Natural Science.
Earth Science
The two major basic parts of plant are Root Shoot
solvent and solute
science
Chemistry and physics
The two part of science question are CAUSE and EFFECT relationship. also exact measurement and calculation.
engine and transmission
Pulp and enamel
the two ajor types of the lockstitch are the upper and lower parts!
not to sure but isn't there 3 ? chemistry, biology and physics
