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.
There are 23 chromosomes in a human sperm or egg (ovum). Of these, 22 are autosomes, and there is one sex chromosome: either an X or a Y. So 23 is the human haploid number. + 3 others found this useful.
