Answer:

The correct answer is D. Umbilical cord

Explanation:

The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).

How many changes to the DNA strand occur in a gene mutation?
ella [17]

Answer:

Changes can be gathered into two principle classes dependent on where they happen: substantial transformations and germ-line transformations. Substantial changes happen in non-conceptive cells. Numerous sorts of substantial changes have no conspicuous impact on a living being, on the grounds that hereditarily ordinary body cells can make up for the transformed cells. Regardless, certain different changes can significantly affect the life and capacity of a living being. For instance, physical transformations that influence cell division (especially those that permit cells to partition wildly) are the reason for some types of malignancy.

Germ-line changes happen in gametes or in cells that in the end produce gametes. Interestingly with substantial changes, germ-line transformations are given to a living being's offspring. Therefore, people in the future of life forms will convey the transformation in the entirety of their cells (both physical and germ-line).
