Hydrogen Fuel Cells There are many reasons to look for new cleaner forms of energy. Fossil fuels‚ being non-renewable‚ will eventually run out. Pollution from burning fossil fuels destroys our environment. Hydrogen fuel cells could be used many places where fossil fuels are currently being used. Using hydrogen as a form of energy can not only reduce our dependence on imported oil‚ but also benefit the environment by reducing emissions of greenhouse gases and pollutants that affect our air quality

Cell Transformation Cell transformation is when a cell takes in DNA from the outside of the cell. It then becomes a component of the cell’s DNA. There are three different ways in transforming the cells. There is transforming bacteria‚ transforming plant cells‚ and transforming animal cells. The purpose of cell transformation is to introduce a foreign plasmid in order to make large quantities of it. In transforming bacteria‚ a foreign DNA is first joined to a small circular DNA molecule known

Cell phones and their everyday use. The invention of cell phones has enabled us to improve our lives in many ways which can be great for some but for others has caused irresponsibly behavior. Most of the time they allow us to multitask but for some it is just a distraction. Cell phones have had a major impact on our lives both positive and negative. They affect how we handle our everyday tasks. They can be entertaining most of the time with all the cool features‚ or help us regarding safety

pluripotent stem (IPS) cells differ from those currently in place for human embryonic stem (ES) cells. An IPS cell is created artificially from skin‚ fat and fibroblasts by reprogramming patient ’s own cells. Scientists believe IPS cells to be a promising source for treating diseases. An ES cell is created by destroying an embryo. Other scientists think ES cells will also be a promising source because it is composed of your own DNA‚ so the immune system won ’t reject the cell.
