In 1963 James Edgar Till discovered that bone marrow transplanted cells in the spleen of mice self-replicated. With the research, Canadian scientist James Edgar Till discovered stem cells that have become a known and controversial subject ever since.

From this, stem cells have become the subject of numerous studies and experiments, and are the main subject of many debates. Experiments have already been performed that tested the influence of stem cells in cancer treatments, cloning, chronic disease treatments, experiments that evaluate the possibility of organ transplantation from animals to humans, tumor treatment, among others.

Several segments of the population have taken a position contrary to this type of research, as they claim that the good of society cannot be obtained from the death of some individuals, even if still in the embryonic stage. The Roman Catholic Church, as well as Protestant churches has defended this position, also accepted by many unrelated scientists and philosophers, that a person's life begins with fertilization, so there is no ethically adequate justification for such research. .

Ernest McCulloch and James Till discovered the stem cell research while working on the mice bone marrow. He found that the different blood cells were formed by the single class of cells.

Experiments on mice and other animals have been conducted to study the stem cells so far. The study of stem cell is useful to cure the genetic defects, Cancer and other harmful diseases.

The graph shows the growth and reproduction in 4 different cells, A, B, C, and D, over time. Use the graph to answer questions b
balandron [24]

Answer: A.

Explanation:

Cells generally have a relatively short lifestyle in that they grow, divide and then die off. This is not the case with cancerous cells as those ones mutate and then multiply such that they eventually form a tumor.

Looking at the graph, most of the cells are remaining at a lower or manageable number because they are dying off. Cell A on the other hand is simply increasing in number which means that it is a cancerous cell as it is increasing its number by mutating instead of dying off like other cells would.
