conditions do cells gain or lose water? Did water move into the cell or out of the cell while it was surrounded by hypotonic solution? The water moved into the cell‚ because there was less water inside the cell than outside (there were fewer water molecules inside). 2. In which direction did the water move though the cell membrane when the cell was surrounded by the hypertonic solution? The water moved out of the cell because there was a higher concentration of water inside the cell than outside

Embryonic stem cells The term "stem cell" in Websters dictionary defines it as "An unspecialized cell that gives rise to differentiated cells"‚ which is a fancy way of saying "stem cells can be used to copy and turn into any other type of cell". To understand Embryonic stem cells‚ we must go back to the Discovery of stem cells in general. Stem cell research first dates back to the late 1800’s‚ when scientist first observed evidence of cells able to produce other cell types. There was a gap in

INTRODUCTION An important aspect of any biotechnological processes is the culture of animal cells in artificial media. These animal cells in culture are used in recombinant DNA technology‚ genetic manipulations and in a variety of industrial processes. Now-a -days it has become possible to use the cell and tissue culture in the areas of research which have a potential for economic value and commercialization. The animal cell cultures are being extensively used in production of vaccines‚ monoclonal antibodies

Stem Cell Research Advancements Tara Cantwell English 215 Professor Amanda McClure 02/10/2013 Stem Cell research could save the lives of many people suffering from diseases. Stem cells are organisms that are crucial in development. These non-specialized cells have a potential to create other cells such as; muscle cells‚ tissue‚ brain‚ and blood cells. Stem cells can even repair and replace damaged cells. With all this wonderful technology in our reach Ethics holds back the development of

Stem Cell Research I have decided to write my paper on one of the most controversial subjects in the United States for the past few years: Stem Cell Research. The problem with this topic is that it’s relatively new and many people don’t realize that stem cell research can eventually provide incurable diseases to be cured in the years to come. There are basically two different sides to this issue: 1) People who want to ultimately provide a cure for unsolvable medical issues 2) The other side

Least Intensive Interventions Mnemonic Device Teach the student strategies to write lengthier stories with organized content. Use a mnemonic device such as “WWW‚ What = 2‚ How = 2” which translates into a story grammar checklist: WHO is the main character; WHERE the story takes place; WHEN the story occurs; WHAT the main character(s) do or plan to do; WHAT happens next; HOW the Story oncludes; and How the character(s) feel about their experiences.
