Answer:Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Explanation:
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.

Answer: Higher infant mortality rates cause higher fertility rates.
Explanation:
Countries with high infant mortality rates are usually countries where families rely on children to help out the family. High infant mortality rates and a need for children means that those people will continue to try to have children until they have some that survive. If more children die, and people need to have more children, there will be a higher fertility rate.
Messenger RNA? if that's a option. not quite sure
metalic
Explanation:
Atoms having a valence of electron of 1 or 2 are metals. They belong to the first and second group on the periodic table.
In metallic bonds, atoms of metals and alloys joins together.
- The formation of this type of bond is favored by the low ionization energy and a large number of electrons in the valence shells.
- The bond is an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms losing their outermost shell electrons.
- Most physical properties of metals can be accounted for by this type of bonding.
