It also showed how IQ has been abused throughout the years from the time of its inception to now and that it has happened in different countries; countries that were considered intelligent and respected for their accomplishments as well. IQ also seems to be effected by the interaction of both genetics and the environment in which one is nurtured and their…

Preparation for Cell Lysis Obtain the mammalian expression vector for homo sapien ESR2 from Addgene. Assemble the vector to code for the proteins snail, slug and twist. Transfect HEK293 cells with the modified plasmids in petri dishes. Allow the cells to grow for 1-2 days so they will express the proteins. Transfer the culture medium to a centrifuge tube to separate it from the cells. Add 1mL of phosphate buffered saline (PBS) to the cells and swirl to mix. Separate the PBS from the cells and…

Society Science explains many of the things in today’s world that, just decades or centuries ago, were complete mysteries. One of the things science has made clear is the fact that sexuality is very biologically based and driven. While this is truthful, it is not one hundred percent accurate. Sexuality is biologically based, yes, but it is shaped by society. Biology defines sex as the way humans reproduce. Sociology takes this definition and furthers it by adding that, while it is how humans…

A very large and growing issue in the health sector today is diabetes. Diabetes being both…

things including their ear shape, length of their fur, and what they last ate before they died. The genes that are collected are used to show how that certain animal or species lived/survived. Proteins which are found in the cells help perform processes and drive the cells. The work done by these scientists have helped the world to better understand ancient creatures. A scientist by the name of Campbell wanted to find out how the woolly mammoth lived and adapted to such cold climates.…

Nanotechnology has a great potential to enhance our society. However, similar to many other technologies, its introduction and implementation raises some ethical issues for the scientists who are developing this technology and for the general public who may benefit from or be exposed to it. Most of the social, economic and ethical issues are exactly the same as those that affect many other high profile technologies. Although the technology is new, the issues it raises have been faced before by…

Claude Bernard “It is what we already know that often prevents us from learning” (Claude 2). This famous scientist wanted to find out about more of the body then what man already knew at his time. Claude Bernard studied and found many discoveries about the human body and its functions. He found valuable information that is still accurate and used today. This paper will walk through Claude’s life and his discoveries, research, and achievement. To start off, his birth was on July 12th, 1813. He…

The beauty about life is that each and every multicellular living being on this planet was created by a sperm cell fertilizing an egg cell to form a zygote. Once the zygote is formed a processes knows as mitosis allows the zygote to develop cells, tissue, and organ systems until all of the proper systems necessary for survival are formed (Witz BW 2004). Conceiving a baby is one of the most beautiful things life could bring someone…

nucleus. To start off, I am going to start with the one in charge of the whole cell or town. The one that is in charge of the cell is the nucleus. In a town it is the mayor or the town hall. There is a reason why I way that is because the mayor makes the laws in the town hall, so basically the mayor is the nucleolus and the town hall is the nucleus.…
