Answer:
the third one is correct
explanation
because atomic number and proton &electron number is same . neutron number is solved as atomic mass minus atomic number ( N=atomic mass - atomic number)
The more energy needed, the higher the melting point or boiling point . As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points.
i would go with true.
Cells that have no mitochondria are unable to convert oxygen into energy, found in the form of adenosine triphosphate (ATP). All multicellular eukaryotic organisms, including plants and animals, have mitochondria in some cells, but prokaryotes and some single-cell eukaryotes do not have mitochondria.
The first stage of cellular respiration is most commonly referred to as glycolysis!
