true or false: All substances can pass freely between the intracellular and extracellular fluids through a phospholipid bilayer.
Komok [63]

Answer:

False

The DNA if these people were collected and PCR was performed to duplicate the DNA. These DNA samples were then analysed on the Gel electrophoresis in which the bands were visualized with the UV light.

In the band, we observe that the size of the DNA fragments was not similar to the DNA sample of the women but a band was of similar size to the father.

Since the bands are of different size of the boy when compared to the mother, therefore, the women are not the mother of the boy.

Thus, No is the correct answer.
