Which of the following genetic changes would be passed from parent to child?
a. a translocation in a nonhomologous pair of chromosomes in a liver cell
b. a mutation in a skin cell caused by uv light
c. the addition of a chromosome in an egg cell
d. a duplication of chromosome 21 during mitosis in a pancreas cell

The addition of a chromosome in an egg cell.

Explanation:

Mutation may be defined as sudden, heritable change in the DNA sequences. The mutation may be caused during the DNA replication or may be caused by the environmental factors.

The mutation that occurs in the gametic cells may pass down from parents to their offspring. The addition of an extra chromosome in egg cell will be inherited in the next generation.

Thus, the correct answer is option (C).

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
