** My Blog ** = **About M**e = My name is Maija, and I am a freshman of the year 2009-2010. I like to play sports, such as, softball, volleyball, and I run in track. I can play the guitar, and I enjoy being with family and friends. The top three subjects that interest me are health, english, and biology. My hobbies include spending time with others, playing instruments, and participating in physical activities.

= **White Pine Tree** =


 * 1) Name-White Pine Tree
 * 2) Scientific Name-Pinus Strobus
 * 3) Organism that infects tree-Blister Rust
 * 4) Provides habitat or food for... (don't guess, research)-This tree provides a habit for forest birds and small mammals such as squirrels.
 * 5) Justify classification of tree to related trees - create classification scheme as a class, identify related species-Adapts well in moist soil, though it grows at a slower pace than other trees if the soil is not right. This tree prefers sandy soils to grow the strongest, and the fastest.
 * 6) Commercial use of tree-Needles are a good source of Vitamin C. Pine bark bread was once fed to pigs and cattle to make them grow well. The bark of the tree was also used to waterproof baskets. The sap can be processed into turpentine. Also used as the common Christmas tree, timber, and paper.
 * 7) Twig characteristics-Twigs are slim, thin, flexible, and the color is a reddish brown.
 * 8) Where tree is found in the world (native to pa?)-All throughout Pennsylvania, and all northeastern states of the United States.
 * 9) Draw or find a picture of a drawing of the leaf to show to the class.

= **Eastern Hemlock** =


 * 1) Name-Eastern Hemlock
 * 2) Scientific Name- Tsuga Canadensis
 * 3) Organism that infects tree- Hemlock woolly adelgid
 * 4) Provides habitat or food for... (don't guess, research)- Ruffled grouse, wild turkey, and songbirds . White-tailed deer use this tree for shelter during the winter.
 * 5) Justify classification of tree to related trees- The eastern hemlock can tolerate and grow well in shaded areas.
 * 6) Commercial use of tree- Once used to make leather, and the bark was once used for harvesting tannins
 * 7) Twig characteristics- Yellow-brown, slim and slender. Many needles cover each twig.
 * 8) Where tree is found in the world (native to pa?)- Nova Scotia westward through New Brunswick, Maine, Quebec, Ontario, Michigan, and Wisconsin.
 * 9) Draw or find a picture of a drawing of the leaf to show to the class.

This creature is part of a very unique species. It holds the head of a polar bear on the body of a giraffe. These animals can be found in the cold Antarctica, or in any of the tropical jungles. This species eats mainly fish, but it also eats leaves, and other small plants. The polaraffe is of the Phylum Chordata. It can run up to 60 mph. They are very gentle creatures that nurse their young with the milk of their bodies. They cannot be found at local zoos because they are very hard to find. They hide with their own kind in places we are unaware of, because they are so well hidden. The only reason humans know this species exists is because we have found traces of their footprints, or hoofprints, and scientists have studied what they excrete. One was also recently hit with a school bus. Only nineteen children were able to see this magnificant creature. It had a few bruises, but it quickly ran back into the wild. If you're concerned, I am happy to inform you that all the children talked to their school counselors and no signs of post traumatic stress were found, except for a select few. I am sorry to say, you will most likely never see a polaraffe.

=Catalase Activity=

Catalase Chart






=Carrots=

Questions:
1. There were simple sugars, starches, and fats and oils found in carrots, while proteins were absent. 2. In carrots, I found that catalase were in active in all but proteins. This means that the catalase did not react to proteins, because they were absent in the carrot. Fats and oils, starches, and simple sugars were present in the carrot, so catalase reacted with it. 3. Other results of my class mates experiments made me realize that my food, carrots, is not as active as ground beef, liver, potatoes, ect. =Biomolecules Webquest= Primary Structure of a Protein This is a sequence of a chain of amino acids.
 * H.**

Secondary Structure of a Protein Occurs when the sequence of amino acids are linked by hydrogen bonds.

Tertiary Structure of a Protein Occurs when certain attractions are present between alpha helices and pleated sheets.

Quaternary Structure of a Protein This is a protein consisting of more than one amino acid.

=Light Intensity Activity= =Photosynthesis Webquest=

1. Photosynthesis-When something takes light and converts it into food. 2. Bacteria, green plants, and protistans, a large group made up of single-celled organisms, all carry out photosynthesis. 3. Six carbon dioxide molecules make one molecule of sugar + six molecules of oxygen. 6H(2)+6CO(2)=C(6)H(12)O(6)+6O(2). 4. A. Carbon dioxide and water are the raw materials used for photosynthesis. B. The products of photosynthesis are simple sugar glucose and oxygen. C. The energy source needed in th reaction of photosynthesis is solar energy. 5. A. The thylakoid is where photosynthesis occurs. B. The cells involved are the mesophyll and the epidermal. C. The organelle involved in photosynthesis is chloroplast. 6. The stomata absorbs water and carbon dioxide and sends it to the plants part where photosynthesis occurs. 7. Stroma- This surrounds the thylakoid and consists of connective tissues and blood vessels. 8. Chloroplasts are contained in the thylakoid. These organelles are involved in photosynthesis. 9.The first part of photosynthesis is the light reaction.This occurs in the thylakoid. 10. The first part of photosynthesis is found in the stroma of the chloroplast and its the light reactions. 11. The second part of photosynthesis is found in the stroma of the chloroplast and it's the Calvin Cycle. 12. In the second part of photosynthesis, ATP and NADPH (Energy carriers), are produced from light reaction. Carbon dioxide is then captured and combined with the hydrogen to make carbohydrates. 13. ATP and NADPH link the two parts of photosynthesis. In the first part, the energy carriers are created and tehn in the second part, they are sent to make carbohydrates.

=Yeast Activity Analysis=

1. The less sugar in the water let off the most carbon dioxide, causing the balloon to inflate. In the 3% sugar water, the balloon was large compared to the 10% sugar water. The 5% sugar water was larger than the 10% sugar water. 2. Sugar and water is dependent, and yeast is independent. 3. Yeast prefers a warm, moist environment. The sugar concentration effects the rising of the bread. The difference in sugar caused different results in other groups. The less sugar, the more the yeast grew. 4. When there was lesser amount of sugar, the yeast grew the most. When there was a greater amount of sugar, the yeast grew less. 5. Yeast carried out anaerobic respiration. Ethanol was produced and carbon dioxide was released in this process. There was no oxygen present.

=DNA Replication=

Steps in picture: 4&3-2-1

Guanine Thymine Adenine Cytosine
 * Bases**

DNA is shaped like a spiral staircase, which is known as the double helix. The DNA replication happens in the stage of interphase during mitosis.

1-The enzymes unwind the DNA 2- The hydrogen bonds break that are holding the two halves of DNA together 3&4-The Left side gains one that was on the right side, such as, phosphates, sugars, and bases The Right side gains one that was on the left side, such as, phosphates, sugars, and bases T always bonds with A, and C always bonds with G. They switch sides, but the bonds never change.
