Cell theory states that all the living organisms are made up of basic structural and functional units, cells. All cells divide and give rise to new cells. All the cells have similar chemical composition. The nuclei acid DNA present in the chromosomes helps in carrying hereditary information from generation to generation. So, in order to sustain life the cells must contain DNA either enclosed in the nucleus or freely floating in the cytoplasm.
The continental drift is what caused plate tectonics
<span>the answer:
The net ionic equation,
H3PO4 (aq) + 3 OH− (aq)------- PO4−3 (aq) + 3 H2O (l),
</span> H3PO4 is a strong acid, (presence of hydrogen H)
OH- is a strong base, (presence of OH-)
so the true answer is <span>strong acid-strong base</span>
