As you probably guessed i am the kind of person that likes to be outside. When i am not at school i am either at sports practice, riding quad or anything else outside. I play many sports such as football, basketball, and track and field. I also race quad which is my favorite sport of the four mentioned. At school i am in the academic curriculum so i also have a lot of homework most nights of the week.

=Scots Pine= -Coniferious -Leaf type- Needles -Leaf Arangment- Opposite -Commercial Uses- Wind breaks, Landscaping, ETC. -Provides habitat for- Birds, Squirrels, and many other small animals -Organisms that affect the tree- White pine weevel top, and pine shoot beetle -Provides food for- Deer, Squirrels, and other small animals -Native to PA?- Yes -Other infor- Scots pine is also used for holiday decor for Christman and New Years celebrations =POEM= Scots Pine Who is tall, woody, and covered in bark Who is the brother of Norway Spruce Who loves wind, rain, and sun Who feels strong, mighty, and important Who needs, water, air, and sunlight Who gives, life, habitat,and food Who fears strong wind, dry soil, and chain saws Who shares the forest, the world, everything Who is tall and strong Who is a resident of the forest Pinus sylvestris

=Classification of Marine Bacteria=

You are //Synechococcus!// You like to hang out on your own, and this solitary microbe is no different. Like you, this microbe prefers staying on the “upper bunk” of the ocean, where it can absorb more sunlight to effectively photosyntesize. And photosynthesize, it does! This microbe cranks out about 25% of the primary production in the ocean. 2a. The steps are organized by using a specific sequence of questions to determine which microbe you are. 2b. To find out which bacteria you are related to 2c. It uses all of the things you enjoy like and other things. 2d. I am closely related to Synechococcus. 2e. I am most different from Heterotroph =BIOMOLECULE/ CATALYST LAB= I found that the room temperature hydrogen peroxide gave the best reaction. The warmed peroxcide gave the second best reaction and the cold gave the least reaction when added to the test tube of the liver "shake." I thought that the warmer peroxside would give the best result because it would be able break down the enzymes better. But to my surprise the room temperature peroxide gave the best result out of all three of them. The result of the room temperature one was actually so good that it came out of the test tube the instant it hit the liver. 1= Absent 2= Present

1.The different biomolecuels found in the dfferent types of food are sugars, proteins, starches, and fats. 2.I found that liver only had proteins. I think that this correct condering the fact that it is meat, and meat is made mostly of proteins. 3. Before this activity i didn't know how many different things were in foods.I knew that they were made of cells but i didnt know baou teach individule biomolecules.

=CATALYST ACTIVITY=

1. A. In conclusion this lab shows us how catalyst reactions and shows us how it works to break things down. B. The peroxide that was cold gave the least reaction of the three. The warmed peroxide was second in reaction and the room temperature was surprising the best reaction.

2. Why are enzymes so important to break down foods?

3. Enzymes are so important to break down food in the human body because they are the only thing that break down the food in the body. There is nothing else in the human body that can do this so the enzymes are almost the most important part of the bodies digestion system.

= = =Chromatography lab= I think that all leaves do not have the same kinds of chlorophyl and pigments. I think this because with each of the different leaves, there was different colors that were extracted with the test was done. Every leaf had some of the same colors, but none were exactly the same. It have come with this conclusion because each of the leaves all had different RF values. I think that all leaves have different RF values because each leaf had different pigments come out at different places across the filter paper. = =

=LIGHT INTENSITY= The higher of the intensity of light, the more efficently photosynthesis can occur. The longer the wave length, the faster photosynthesis can occur. Some plants require different pigment color in order for photosynthesis to happen the right way.

=YEAST RESPIRATION LAB=

GRAPH OF DATA BREAD DOUGH = = BEFORE AFTER My ballon had a circumfrence of 12cm and a radius of 1.96cm

1. Yeast can be affected by many things. One conclusion of this is that yeast reacts better in a warm environment than in a cold one. Another conclusion is that yeast will react much more if there is alot of sugar present for the yeast to break down.

2. The dependent variable was how much the yeast caused the bread to rise. The amount that the bread rises, was affected by the independent variables such as how much sugar was in the solution and how warm the dough was.

3. According to the data that i got, the yeast prefers a warm environment with a lot of sugar to break down. The more sugar there was, the more the bread rose, and the warmer the envirnment, the more the bread rose. The more sugar added, the more that the yeast rose/

4 The higher the concentration of the sugar, the more that the bread rised. So, the 10% solution rose more that the 7% solution. There was actually a pretty big difference in how much the yeast rose in the 10% compared to the others.

5. Yeast preformed anaerobic respiration. I think this because yeast produces ethanol gas when it reacts and this is called alcohol fermentation, which does not use oxygen, which makes it anaerobic respiration.

=DNA REPLICATION PROJECT=

==

__**Telomeres**__ Telomeres are at the end of chromosomes and sometimes appear as stretch like marks. They also keep the different ends of the chromosomes from getting attatched to each other, which would be bad.

__**Okazaki Fragments**__ These are created on a lagging strand of DNA during replication and are usually really short.

__**DNA ligase**__ 1- links okazaki fragments during the process of replication 2- only found in non-dividing cells 3- Used to help combine the fragments bag together 4- Repairs the final two strands in the final step

__**Telomerase**__ Used to cause telomeres to lengthen and is mostly found under the germline and in mostly cancer cells.

__**Cancer**__ Most of the time cancer only appears from stomatic cells. Telemerase levels are very high in these cells and keeps their telomeres from shortening.

__**Transplanted Cells**__ First, cells are removed from a person or animal. They then look for what the cells are lacking and then replace the cells with new ones that will multiply and begin to heal the person/animal. The major problem with this is that the cells die after each use of this process.

__**Cloning**__ This is when you make and exact copy of a strand of DNA. You can clone just about any living thing on earth, but it is a very complicated process and seldom works. To do this the DNA is extracted then the strand is copied exactly by a scientist or machine.

__**Aging**__ In aging, the ends of the chromosomes become frayed such as the end of a shoe string. After a while, the strands become so frayed that they cannot replicate anymore and cell death occurs.

=CLASS TRAITS LAB=

1. The two traits that I choose are hitchhikers thumb and free or attached ear lobes. Having hitchhikers thumb is a recessive trait and not having it is dominant. Having a free ear lobe is a dominant trait and having an attached ear lobe is a recessive trait. The numbers portray correctly whether or not they are dominant or recessive and match with the chart on the website.

2. As I looked an compared the data between our class and classes else where, I noticed that many of the traits had similar numbers of male and females. I believe that some of these traits are more common in males and females based on the results I have seen comparing all the classes.

3. The two traits that I am choosing are widows peak and no color blindness. Out of 11 girls 2 had widows peak. Out of 13 boys, 4 had widows peak. This is a recessive trait. Nobody in our class had any color blindness whatsoever. So, the numbers were out of 11 girls, 11 had no color blindness and out of 13 boys, 13 had no color blindness. This is a dominant trait.

4. In my parents and I, we all three have hitchkikers thumb. The genotype of this is that we all three have this as a dominant trait and the phenotype is that we all three have the hitchhikers thumb which is very visible. All members of my family clear back to my grandma have this trait and always have.
