Primary succession is a method of fertilizing soil that was barren and had never supported plant life, for example soil left over by a moved glacier of lava.
There are many reasons why researchers use mice as animal models in science and medicine. A huge reason why mice are used is that their genetics and behavioral characteristics are very close to humans. So, having an animal model for Huntington’s Disease would help scientists be able to study the disease further and make advancements in treatment options in a far less costly and a much safer way than studying it in humans. Mice as animal models can also help in a huge way because their lifespans are very short compared to humans (they only live about 2-3 years). This allows scientists to be able to study the affects of the gene over many generations in a much shorter amount of time.
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
