Answer:
The sum of the numbers of protons and neutrons in the nucleus is called the mass number and, expressed in amu, is approximately equal to the mass of the atom. An atom is neutral when it contains equal numbers of electrons and protons.

Answer:
It occurs during the continuous glyceraldehyde-3-phosphate phosphorilation.
Explanation:
Hello,
First of all, the process of extracting energy from glucose is called glycolysis. Then, the NADH oxidation happens during the glycolysis' sixth step when the glyceraldehyde-3-phosphate is phosphorilated by the addition of another phosphate group due to the electron carrier NAD+ which produces NADH. In fact, that is not the requested oxidation but it occurs when this process becomes continuous as long as the NADH is oxidized back to NAD+ to keep on the process.
Best regards.
Answer : The correct option is, (C) 10-mL volumeric pipet.
Explanation :
Graduated cylinder : It is a measuring cylinder that is used to measure the volume of a liquid. It has a narrow cylindrical shape. The marked line drawn on the graduated cylinder shows the amount of liquid that has been measured.
Pipet : It is a type of laboratory equipment that is used to measure the volume of a liquid. It is small glass tube and the marked line drawn on the pipet. It is used to accurately measure and transfer of volume of liquid from one container to another.
Volumetric flask : It is a type of laboratory tool that is also used for measuring the volume of liquid. It is used to make up a solution to a known volume. It measure volumes much more precisely than beakers.
Beaker : It is a type of laboratory equipment that has cylindrical shape and it is used for the mixing, stirring, and heating of chemicals.
As per question, we conclude that the pipet is most precise than other devices because in pipet the marking lines are more accurate. Thus, it can be used to measure volume to precision.
Hence, the correct option is, (C) 10-mL volumeric pipet.
