The Teenagers Brain

An extremely important part of the brain is the grey matter, gray matter contains neurons which help your mind communicate with your body to perform a physical action. As you grow older the volume of grey matter increases then declines.

The volume of grey matter is at its highest when your a child then slowly declines over the time the child grows. In the early ages when the teenager is growing up start to gain synapse helping information pass between different nerve cell, a synapse acts as a junction between two nerve cells.

When you turn into an adult you start a process called pruning, pruning is a process where you start to lose synapses, it's important to exercise your mind so you prune less. As you mature your connections to different parts of the brain will increase, increasing the speed in which your body can transmit pulses.

It's also important that you get plenty of sleep, adolescence brings with it a change of sleep regulation, inadequate sleep is a major contributor to depression and have a major affect on the maturing child's attitude. Since I am still maturing myself these are just the things that I did the research on, the rest is left for me to learn while I grow up.

Hurricane Katrina

Hurricane Katrina struck the United State's Gulf Coast in he morning of August 29, 2005. The total death toll that Katrina caused is unknown, the estimated amount ranges from 1,200 to 1,800+, Katrina hit several states some of these are: Florida, the Gulf of Mexico, and New Orleans. New Orleans was hit the hardest and the amount of damage it caused was catastrophic. The aftermath it brought caused over $100 billion dollars in damage. Many residents of Mississippi, Lousiana, and Alabama   had their homes destroyed by the storm. Hurricane Katrina was about 400 miles long reaching winds of more than 100 miles per hour. The storm caused so much flooding that nearly 80 percent of the city was covered with water, people had to break through their attic and climb to the roof for safety. 

The Cell

All living organisms can be classified into two cell groups Prokaryotic and Eukaryotic. Prokaryotic cells are smaller, independent from the other cells and less complex than Eukaryotic, Prokaryotic cells take form of bacteria and blue-green algae, and Archaea. Eukaryotic cells unlike Prokaryotic contain a nucleus. Eukaryotic cells are bigger more complex and are seen in animal, plants, protists, and fungai. The Eukaryotic cell contains many organelles I will explain some of them and their jobs in the cell. The nucleus contains the DNA the nucleus is the one controlling the cell and what cell it become. Nucleolus is contained in the Nucleus. The nucleolus' job is to assemble the ribosomes. The ribosomes job is to help build protein, the ribosome is a large subunit over a smaller subunit while messenger rna goes through building the protein. The Cytoplasm made up of Cytosols. Cytoplasm acts as the internal-substructure for the cell. All the contents of the Prokaryotic are stored within the Cytoplasm. The lysome or the suicide sac has the ability to break down all sorts of biomolecules. The lysome said job is to  digest the unwanted materials from the Cytoplasm. The reason this organelle has a nickname of the suicide sac is because when this organelle pops the digestive juice spreads to the whole cell eating itself. These are just some of the many organelles inside a Eukaryotic cell.

DNA

This is my report on what makes DNA. To know what makes DNA all you really need to know is what is a Nucleotide and the three parts of a Nucleotide. The first part is the Nitrogenous Base it's basically a nitrogen which has a molecule that has the properties of a base. The second part of a Nucleotide is a Deoxyribose sugar the reason they call it that is because in the rna its group is called ribose sugar Anderson hydroxyl group contains oxygen while deoxyribose sugar doesn't contain oxygen. The last part is a Phosphate which is familiar with ATP, ATP contains three Phosphate groups. The backbone of DNA contains numbered prime carbons which travels from 3' to 5' DNA is also known to be anti-parallel meaning it goes from 3' to 5' on one side and goes in the opposite direction in the other side.
