The acidity of a solution is typically measured by pH. A pH of 7 is neutral. A pH below 7 is acidic, and a pH above 7 is basic, or alkalotic. Normal blood pH is 7.4. Having acid in the blood means that the pH is below 7.4, and excessive protons may be found in the blood.
The number of chromosomes in the secondary spermatocyte are 23 but each chromosome having two chromatids, while the chromosomes in the spermatid are also 23 but each chromosome is made up of one chromatid.
The sperm cell and the egg cell that come together to form the zygote each contain half the normal amount of DNA. There are 46 chromosomes in a typical human cell. The sperm and the egg each contain only 23 - one copy of chromosomes 1 through 22 plus an X or a Y. Egg cells can only contain an X but the sperm can contain an X or a Y.
