Answer:
A polar molecule simply means the charges are not exactly even throughout the molecule. Some parts are slightly negative (outside the oxygen), and some parts are slightly positive (outside the hydrogen atoms). Water is polar because the highly electronegative oxygen atom attracts electrons to it, making the region around the oxygen more negative than the areas around the two hydrogen atoms. This concept is important to understand how water bonds.
Answer:
D. Phosphate group
Explanation:
When oxygen is added to a carbon chain, one of the predicted outcomes is the addition of a phosphate group to ADP, which generates ATP. Furthermore, during cellular respiration, biological energy is converted to generate adenosine triphosphate, which is used by the cells for energy.
Pure water has a ph level of 7
