= = flat = = =About Me=

Hi, I'm Dakota, I am a freshman at PHS. I love sports, I play baseball, football and basketball. Baseball is my favorite. I also like to hang out with friends and play xbox live every once in a while. I usually just play sport games on xbox like MLB, Madden, or NBA but i also sometimes play Call of Duty. Another thing I like to do is listen to music. I like artists like Biggie, Tupac, Wiz Khalifa, Tyler the Creator, Eminem and Jay Z.

=Tree Name: Elm= The tree that I have is the Elm. The scientific name for it is //__Ulmus americana L__//. Other trees that it is related to are the Water Elm, the Slippery Elm, and the Rock Elm. There are 30 or 40 different species of Elm's in the world. It is a deciduous tree with a serrated margin, alternative leaves and it is simple. Some distinctive characteristics of the tree are it's bark is dark gray to a gray brown bark, the leaves are 4-6 inches long, and the bark also has long "corky" ridges. A use for the tree is since it is a hard, tough wood it is used for the manufacturing of boxes and barrels.

=The Pitch Pine= The name of my tree is the Pitch Pine, it's scientific name is the __//Pinus rigida//__. Some of the trees that it is related to are the Loblolly Pine, the Shortleaf Pine, and the Pond Pine. There are around 115 different species of pines. It is a Coniferous type tree with 3 needles in a bundle. Some characteristics of the tree are the needles can be anywhere from 6-13 cm long. The cones on the tree can be from 4-7cm long and they are oval shaped with prickles on the scales. This tree also has shoots that can grow from the trunk that is an adaption for fire. Some uses for this tree is since it is a decay-resistant wood it is used to make railroad ties and fencing. It is also used for fuel.

=Biomolecules in foods= The first food we tested was milk. We found that there were no simple sugars present in the milk. There were also no starches present in the milk. However, there were proteins found in the milk along with fats and oils. Another food that we tested was lettuce. We found that It did not have any simple sugars, starches, fats and oils, or proteins present in it. Some biomolecules found in foods that were surprising to me were fats in avocado because avocado’s are fruits and you normally don’t think of fruits as being fattening. Also, no fats in the egg white surprised me because egg yolk has fat so I thought egg white would have fat too. Some biomolecules that I expected to see in some foods that weren’t were protein in apples. It did not have any but people always say that apples are good for you so I thought it would have some protein in them. Also, lettuce did not have any sugars, starch, fats, or protein in it and that is surprising because it basically has no nutrients or anything in it at all, if it does not have any of these. Based on nutrition information though, bananas should have a little bit of fat in them. Also, avocado should have protein in them. Potatoes should also have protein in them.

 * 1) **What are catalysts?**
 * They speed up and cause chemical reactions**


 * 1) **What is the importance of enzymes for living beings?**
 * They break down food for humans**


 * 1) **Is there a difference between the initial and the final energy levels in catalyzed and non-catalyzed reactions? No, there is no difference between the initial and final energy levels in catalyzed and non-catalyzed reactions. However, Catalyzed reactions are much faster than non-catalyzed.**
 * 2) **Why can it be said that the enzymatic action is highly specific?**
 * Enzymes can be said to be highly specificeach enzyme has a specific chemical reaction that it causes and speeds up.**


 * 1) **Describe a reaction without the presence of an enzyme and then with an enzyme.**
 * The reaction without an enzyme takes very long to occur. With an enzyme the reaction speeds up very much and it occurs in only a few seconds.**

=DNA extraction from human cheek cells lab homework= NO, not everybody in our group had about the same extraction results. Ethan had a lot more DNA that could be seen than Eric, Ruben, and I. This is the because we all have different day to day activities, DNA, amount of saliva, and differences in how we scraped our mouth (whether we scraped it easy or hard and for how long). The amount of DNA extracted is affected by your day to day activities because if you exercise a lot you have more saliva in your mouth so there would be more DNA that could be extracted. Also, if you exercise a lot your cells have to work harder and you need more of certain cells to be able to carry out the exercise
