one parent is 6 feet tall and the other parent is 6 feet 4 inches tall.

what is the best prediction for the height of the offspring of the two parents?
a.
the offspring will be about 6 feet tall, but the exact height cannot be predicted.
b.
the offspring will be exactly 6 feet 2 inches tall because it is in-between the two heights.
c.
the offspring could be any height because the height of the parents is not important.
d.
the offspring will be either exactly 6 feet tall or exactly 6 feet 4 inches tall.

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
