Dad: TtBb

Mom: ttbb

You have to use distribution for dihybrid crosses.  Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait.  So for example with Dad, I will number the traits:

T(1)t(2)B(3)b(4)

To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb.  Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.

Cross:

                 tb

TB           TtBb

Tb           Ttbb

tB            ttBb

tb            ttbb

All of the homeostatic mechanisms that monitor and adjust the composition of body fluids respond to changes in the:
a_sh-v [17]

Answer:

The correct answer would be - extracellular fluid.

Explanation:

Changes in extracellular fluid helps the homeostatic mechanism to monitor and regulate the composition of the body fluids. This process involves regulatory hormones such as anti diuretic and aldosterone in order to maintain body fluids.

It is easy to regulation of the extracellular fluid than trying to regulate 100 trillion cells present in Intracellular fluids as ICF have 10% more water in comparison of ECF.

Thus, the correct answer is : extracellular fluid.
