Answer:
I only know number one answer hope it is helpful
Conduction is the transfer of heat through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know there is thermal motion of the atoms and molecules at any temperature above absolute zero.) Heat transferred from an electric stove to the bottom of a pot is an example of conduction.
Some materials conduct thermal energy faster than others. For example, the pillow in your room may the same temperature as the metal doorknob, but the doorknob feels cooler to the touch. In general, good conductors of electricity (metals like copper, aluminum, gold, and silver) are also good heat conductors, whereas insulators of electricity (wood, plastic, and rubber) are poor heat conductors.
The nuclides 16O8 and 15O8 differs in their atomic weight. 16O8 has an atomic weight of 16 amu while 15O8 has an atomic weight of 15 amu. They also differ in the amount of neutrons, 16O8 has 8 protons and 8 neutrons (16 - 8) while 15O8 only has 7 neutrons (15 - 8 protons). <span />
C, that cells cannot be created nor destroyed.
Cells are produce by other cells. Cells can not be man-made nor destroyed.
