Nucleus is the largest organelle in the cell and contains all the cell's genetic information in the form of DNA. The presence of a nucleus is the primary factor that distinguishes eukaryotes from prokaryotes.
The three ways that heat is transferred are as follows:
Conduction, convection, and radiation.
Radiation is when heat is transferred in waves. It is the only type of transfer that can occur in a vacuum, so that is how heat reaches earth from the sun.
Conduction is when heat is transferred between solid objects. That is how heat is transferred between objects on the earths surface.
Convetsion is when heat is transferred through a liquid. This is how the ocean heats all the way through, rather than just the surface.
