heat
the main purpose of the turbine in the turbojet engine is to? The turbine rotates the compressor, compressing the inlet air. Often, electrical generators and hydraulic pumps are attached to the turbine via gears also. drive the compresser

plants
My son has to do a project on monocots and dicots, which I know are plants but he has to have 4 examples of each and place them on a poster board tell about them, etc. and to do a rubric about this project. I am having trouble finding what they are and the examples since he le...
