discovered the endless possibilities of the so called embryonic stem cells. It has been said that these cells have the ability to repair an entire tissue or even create a copy of it. It is also said to be a potential cure for innumerable serious diseases such as the Alzheimer and the Parkinson’s disease. This is why stem cell research should definitely be funded for the enormous impact it can make in the medical field. Stem cell research is perhaps one of the most controversial topics in modern day

require more efficient sources of power. At the forefront of research for these power sources are hydrogen fuel cells. This power source takes in the most abundant element in the universe‚ Hydrogen‚ and yields immense power without combustion or pollution. The three aspects of this scientific breakthrough are the fuel cells‚ hydrogen production‚ and hydrogen storage. Fuel cells are the devices with which Hydrogen is made into electricity. These use a technology much similar to that of something

Animal and Plant cells consist of most of the same cell types‚ but the whole shape of the cell is quite different. An animal cell is a round‚ uneven shape‚ whereas the Plant cell has an affixed shape. They have a more of a rectangular shape. Chloroplast‚ Vacuole and the Cell wall are only found in Plant cells. The Chloroplast is the organelle for the whole system of Photosynthesis. Chloroplasts are found in mesophyll cells (which are found in the leaves) of green plants. They convert light into

Eukaryotic Cell Division Cells must continually grow and divide in order for an organism to grow‚ maintain its structure‚ and reproduce. Cell division involves the replication‚ or copying‚ of the complete set of hereditary information. It also involves the equal distribution of the genetic material in the resulting cells. The hereditary information of organisms is contained in large molecules called deoxyribonucleic acid‚ DNA. Objectives Upon completion of this laboratory

“The cells in your body are tiny-a row of about forty would fit into 1mm. But although they are too small to see with the naked eye their complexity is remarkable. A single cell can be thought of as an organised chemical system‚ separated from its disorganised surroundings by a membrane” (Boyle et al 1999) First here is a brief summary of major eukaryotic organelles and their structures. The nucleus is the largest and most prominent organelle in the cell. It is usually spherical and about 10um in

In many of the readings we have explored in class about Chinese culture have many similarities and differences with my experience of American culture. For example‚ the way businesses are ran‚ are different. There is no such thing as suing in China. Also people’s jobs are set in stone so China doesn’t have as hard working citizens. In both cultures I think the mixing of age groups is similar. Something I think is really different‚ is how people in China seem to receive an equal pay as their associates
