Which statement about identical twins and fraternal twins is correct in regards to DNA? A. Identical twins have different DNA, and fraternal twins have different DNA.
B. Fraternal twins share the exact same DNA, but identical twins do not.
C. Identical twins and fraternal twins share the exact same DNA.
D. Identical twins share the exact same DNA, but fraternal twins do not.

D. Identical twins share the exact same DNA, but fraternal twins do not.

Explanation:

Identical twins are the twins formed from one egg provided by their mother and one sperm provided by their father. In contrast, fraternal twins are formed from two different sperms and two different eggs from the same father and mother.

Due to the fact that identical twins are as a result of one fertilized egg dividing into two, they share the same exact DNA. On the other hand, fraternal twins do not share the same exact DNA because they are formed from separate eggs and separate sperms.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
