In the beginning of the book Deborah wasn’t interested in seeing her mother’s cells. Over time she has learned more and more about Henrietta and how her cells contributed to science. With this knowledge she was then ready to overcome her fear of going to Johns Hopkins and seeing the cells. We can infer that Skloot used this as one of the pieces of evidence to prove how Deborah mourned her mother. Deborah had to do this later in life because she was so young when Henrietta died, and would not have been able to understand why and how she died. When Skloot was writing the book, her and Deborah became close and was one of the few people who would explain Henrietta’s cells to her. This learning about her mother helped her understand how her mother

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms, such as the unicellular bacteria and protozoa; others, such as nerve, liver, and muscle cells, are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas, which are 0.1 micrometer in diameter, to the egg yolks of ostriches, which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function, all cells have a surrounding membrane and an internal, water-rich substance called the cytoplasm, the composition of which differs significantly from the external environment of the cell. Within the cell is genetic material, deoxyribonucleic acid (DNA),

Salt water desalination is not only an alternative source of drinkable clean water, but also a controller of the natural water resources which are regarded very limited compared to the copious sea and ocean water. Consuming fresh water coming from lakes, rivers and springs may lead to different problems, such as drought, pollution, and soil erosion. Shortage of pure water, thus, makes large areas of land not dead, polluted and not suitable for living. Water unbalanced consumption may result even in increasing desertification. Furthermore, there are many living beings and crops which mainly depend on fresh water coming from lakes and rivers (Majumder, 2015). Such imbalance endangers their life. It also influences the ecological system badly, and causes diseases originated by water pollution. For this reason, increasing dependability on desalinated water can help to control the consumption of fresh water and reserve it for a sustainable environment and a balanced system of living. This saves soil from erosion, protects large areas of land from desertification, prevents unhealthy diseases, and protects human, animals and plants life from being endangered severely by water

As you can see that 72 percent of Earth is covered in water, but 97 percent of that water is salty ocean water and is not good for drinking (Pete). Is the salt water that can only be consumed by only humans and other species. Why should we save water? the whole world revolves around it . Living in one of the most spoiled countries in the universe can make it difficult to understand , But just like we put the man on the moon we can help save water for those in need . Water is a privilege , a lot of us take it for granted . Many countries don 't have fresh clean running water to rely
