For many decades‚ HeLa cells have helped scientists develop many achievements in vaccination‚ mapping chromosomes‚ and even cloning. HeLa derived from the first two letters of the first and last name of Henrietta Lacks. These cells were taken from her in the 1950’s without her or her family’s knowledge. Only twenty years after her death did they discover its’ existence. Living as African American women of lower economic status during Henrietta’s time compared to life now are very different lifestyles

The Progress of the Atomic structure Different theories about the atomic structure were introduced over time. These theories changed as a result of development of different experiments. Leucippus was the first to introduce the theory of atomism‚ however he didn’t write about his theories in detail. However‚ Democritus‚ his student wrote about the theory of atoms in detail. He theorised that everything was composed of atoms and that atoms are solid and indestructible. He also had a theory that

Types of lung cancer 1. Non-small cell lung cancer is the more common of the two types of lung cancer. It generally grows and spreads slowly. There are five types of non-small cell lung cancer. Each type has different kinds of cancer cells. Each of the types grows and spreads in different ways. Causes of Lung Cancer The main cause of lung cancer is smoking tobacco (most often through cigarettes). Between 80% and 90% of lung cancers are due to smoking. People who are affected by Second-Hand
