Other scientists suggest that the structure aids the parasite to divide into two when it is multiplying in the human bloodstream. Scientists found out that the flagellum had about 300 proteins some of which were unique

1. There are many ways in which human activities may lead to an imbalance in biochemical cycling: Something that the natural environment is unfamiliar which can harm the chemical imbalance. One of the many negative impacts caused by eutrophication and increased algal growth; is a decrease in the oxygen available, known as anoxia. These anoxic conditions have the ability to harm fishes and other aquatic animals. However, it is true that algae produce oxygen, but that is possible when an enough amount

Simran Mann Negative Opinion Paper Biology 3000 Harvesting Embryonic Stem Cells Harvesting embryonic stem cells can be an argumentative topic with differing opinions. I believe by researching and experimenting on embryonic stem cells, the results can be beneficial to society through medical treatments. I believe this research will benefit medical science into further advancement. The human body contains more than 220 differentiation cell types that are acquired from a collection of cells that
