Which statement correctly describes cancer formation?
AleksandrR [38]

Answer:

Cancer is formed when there are mutations in a number of genes.

Explanation:

Malignant tumors are gene diseases which do not mean that cancer is necessarily an inherited disease (only in 5-10% of cases the cancer is inherited) because the vast majority of other tumors are the result of somatic, ie secondary, mutations that lead to malignant transformation.

Only 2% of human diseases are monogenic (caused by a change in one gene). The remaining 98% of the disease is either polygenic (caused by a change in several genes at the same time) or epigenetic (caused by non-genetic or post-genetic disorders of cellular molecules).

tatiyna

Answer:

The correct answer will be option-pollen.

Explanation:

The pollen are the male gametophyte which is produced in the seed plants.

The male gametes fuse with the egg cell and form the embryo inside ovary which matures and forms seeds.  The vascular seed plants lack these pollen but instead produces male gametes in gametangia which are replaced by the pollen in the seed plants.

Thus, option-pollen is the correct answer.
