For the source material please read the Radiolab segment, as well as the two articles on Dr. Gey's use of Henrietta Lack's cells from the biomedical test chapter 3.

Answer:

Dr. Gey's use of Henrietta Lack's cells after 24 years was not unethical due to his effort to figure out what was wrong with cells and why it happened to Henrietta.

Even if he did his intentions were to figure out how to treat cancer and help many people from the lethal condition. His effort made it possible to grown immortal human cells in culture. That help in developing the polio vaccine, and many other milestones.

Force

Explanation:

Answer:

A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects.

Answer:

The somatic cells of fruit flies contain eight chromosomes, which means they have two sets of four chromosomes. Meiosis is the process by which sex cells are produced. Sex cells are haploid, which means they have one set of chromosomes.

Explanation:

Fruit flies have two sets of four chromosomes because their somatic cells have eight chromosomes. The process through which sex cells are created is called meiosis. The haploid nature of sexual cells means that they only have one set of chromosomes.

In sexually reproducing organisms, meiosis is a unique type of cell division of spermatids that results in the production of gametes, such as sperm or egg cells. Two rounds of division are necessary, and the end product is four cells with just one duplicate of each chromosome.

When the chromosome count in daughter cells is decreased to half that of the parent cell during meiosis, the process is known as reduction division. For instance, while a human cell has 46 chromosomes, the egg and sperm cells created by meiotic division only have 23. In the above given example, fruit flies have two sets of four chromosomes as their somatic cells have eight chromosomes.

Thus, fruit flies have two sets of four chromosomes because their somatic cells have eight chromosomes.

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).

Answer:

to masticate food

Explanation:

In adults, all the bones of the skull, except one, are fused together by immovable joints referred to as sutures. The sutures are fibrous joints which hold the bones of the skull together to form a rigid and strong structure that protects the brain. Skull bones fuse around two-years (18 to 24 months after birth). The only skull bone that is not fused by sutures in adults is the mandible, which is used to masticate food.
