Answer:

To summarise, a parent cell divides by mitosis (doubling the DNA then splitting) and then divides again to have 4 daughter cells with all different DNA in and all with only half the amount of DNA as a normal body cell. This stage is meiosis. They make sperams and eggs which fuse together in fertilisation and once fertilised the cell will divide by mitosis to create embryos and further to grow into a fetus.

The ka values for several weak acids are given below. which acid (and its conjugate base) would be the best buffer at ph = 8.0?
Pie
One of the best buffer choice for pH = 8.0 is Tris with Ka value of  6.3 x 10^-9.

To support this answer, we first calculate for the pKa value as the negative logarithm of the Ka value: 
     pKa = -log Ka

For Tris, which is an abbreviation for 2-Amino-2-hydroxymethyl-propane-1,3 -diol and has a Ka value of 6.3 x 10^-9, the pKa is
     pKa = -log Ka
            = -log (6.3x10^-9)
            = 8.2

We know that buffers work best when pH is equal to pKa:
     pKa = 8.2 = pH 

Therefore Tris would be a best buffer at pH = 8.0.
