Henrietta Lacks was a young African American woman. Doctors experimented on her in order to form the HeLa cells, which was an immortal cell line, obtained from her body, and used in scientific research. She was born in Roanoke, Virginia, and known by the name of Loretta Pleasant. When her mother died, she changed her name to Henrietta Lacks, and was sent to live with her grandfather in an old slave quarters. She roomed with her cousin, Day Lacks, who later fathered her two children, Lawrence and

World War 1 was a moment in American history that will forever leave its mark. There were positive and negative factors that came as a result of this brutal bloodshed. There were new types of technology formed that proved useful to our military, new tools, and leaps in medical advances that that helped push the medical fields to its limits and a greater acceptance of women. Despite the bloodshed of world war 1, it was the impetus of the medical advances that help shape the world we live in today

The science of human cloning is one of the most fascinating entities of the 21st-century biology. The announcement of a cloned sheep ignited an international debate in the late 1990s; two and half decades later, the debate is still very much alive (Li 1-2). The researchers at the Roslin Institute, Scotland, announced that they had fruitfully cloned an adult mammal (Caplan 1-3). The procedure used in cloning is called somatic cell nuclear transfer. It involves the transfer of the genetic code from

Isotopes are essential to the universe in a chemical and even a social aspect, standing as a variation of an element portrayed as unique. Important questions surround isotopes, how are they distinctive and ultimately what is an isotope? To answer that question, isotopes are a form of an element that differs in the number of neutrons in the nucleus but does not differ in protons of that element. An isotope in particular that contributed to society is Plutonium-238, which is understood to be a radioactive

The Second Industrial Revolution tremendously helped our society become what it is today. Before it occurred, the universe was believed to work like a machine. It has reshaped society through the different inventions and ideas that were made. The Second Industrial Revolution also had ideas and inventions that hurt society. Although the Second Industrial Revolution has led to poor thoughts, it has made our society extremely advanced because of new social thoughts, inventions made by people, and different

Immortal Life of Henrietta Lacks, by Rebecca Skloot starts off with Rebecca Skloot’s narration, of the first time she had heard of Henrietta Lacks. Henrietta Lacks had cervical cancer but technically died of uremic poisoning. When she was treated with radium, they took a sample of her cells and sent it to a scientist by the name of George Gey. Gey wanted to find cells that didn’t stop multiplying even after they were out of the body, and Henrietta’s cancer cells were the 1st known cells in history to

methods. One process of disposal involves injecting the wastewater deep into the ground (NYC Environmental Protection, 2017). If disposed inadequately, there are chances that the wastewater could leak back into the surface, along with heavy metals, radium isotopes and other waste, with the possibility of leaking into groundwater and surface water sources (Zucker, 2017). In the case of New York City, the Catskill-Delaware watersheds lay on top of the Marcellus shale. This watershed is the source of

target of radioactive or nuclear weapons and devices, this includes the use of a conventional explosive device that disperses radioactive material, known as a dirty bomb. Historical Information: Back in 1902 when Marie & Pierre Curie were isolating radium, a radioactive

1869 - Mendeleev produced a periodic table based on atomic weights but arranged 'periodically '. Elements with similar properties appeared under each other. 1894 – William Ramsey discovered the Noble Gasses. 1898 – Marie and Pierre Curie isolated radium and polonium pitchblende. 1913 – Henry Moseley determined the atomic number of each of the elements. 2. The scientist that has been chosen concerning their significance towards the periodic table is Dimitri Mendeleev. Although Mendeleev was one

Energy has always been the driving force that help mankind developed. From the First Industrial Revolution, steam engine powered by coal was developed. Then the Second Industrial Revolution come with the development of combustor engine and petroleum. Today, oil has become an essential source of energy for production and our everyday life. The demand keep on increasing which lead to the growth in scale and quantity of oil production all over the world. It has led many companies to overlook the benefit
