Answer:
Melting point
Explanation:
Pure substances have sharp melting and boiling points while impurities lower the melting point and raise the boiling point
Answer:
Nucleic acid is an important class of macromolecules found in all cells and viruses. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.

In this item, I supposed, that we are determine the molar fraction of oxygen and carbon dioxide in the sample. This can be done by dividing their respective partial pressures by the total pressure of the sample.
O2 : mole fraction = (100.7 mmHg) / (763.00 mmHg) = 0.13
CO2 : mole fraction = (33.57 mmHg) / (763.00 mmHg) = 0.044
Answers: O2 = 0.13
CO2 = 0.044
Chemical bonds hold atoms together to form compounds through the sharing of electrons or the transferring of electrons.
Bio is not my strongest subject, but I am pretty sure that a pyramid of numbers differs from an ecological pyramid because it displays the number of organisms at each trophic level
