elodea with salt



Elodea

Elodea Facts: - The elodea has only 3 leaves in the whorl and no midrib teeth. [] - The elodea is aided in growth with silty sediments and water that is rich in nutrients. [] - Its an important part of lake ecosystem and provides a habitat for animals. []

hydra -The hydra belongs to the phylum Colenterata and the class hydrozoa. -They are about ¼ of an inch long and consist of about 100,000 cells. [] -Hydra has an amazing regeneration power. []

Questions: 5.The cilia and flagella move by locomotion. Cilia does this by hair like organelles that beat in rhythmic waves in water. Flagella uses lash like appendages to move through water. The cell structure is exactly the same but some differences very from the size. These structures are used to bring food closer, and they help them use sensory appendages. Other organisms that have these could be humans because they use appendages to live. Cilia could be plants. 6. The elodea with salt was smaller and more condensed. This was hypertonic so the water in the elodea moved out into the water. Therefore, the elodea in normal water was larger because it was filled with water. This was hypotonic so the water moved into the elodea.

=Biomolecules in Food Lab=


 * **Food** || **Simple Sugar** || **Starches** || **Protein** || **Fats and Oil** ||
 * **Egg Yolk** || Negative || Negative || Positive || Positive ||
 * **Potato** || Negative || Positive || Positive || Negative ||
 * **Processed** **Oatmeal** || Negative || Positive || Negative || Negative ||
 * **Green Banana** || Negative || Positive || Negative || Negative ||

2. No biomolecule was found in every food, potato, egg yolk, processed oatmeal, and green banana, but they all tested negative for simple sugars. We were surprised that the green banana tested negative for simple sugars and proteins. We were also surprised that the oatmeal did not have protein. 3. Yes there were a couple differences when comparing our data with the other teams. For example, The Ice Cream Squad, had oatmeal positive for sugars while we had negative. Also, we had green banana negative for sugar, fats and oils, while they had it negative. They had the egg yolk positive for starch and we found it to be negative. With the potato they had negative for simple sugars while we had positive. This could be because one of the groups could have miscalculated time or not observed correctly.

**Enzyme lab**
The hot peroxide had the highest reaction: Kyle Yoho (also added the chart) The cold hydrogen peroxide had the greatest reaction with the liver, the hot came close behind with a 3 and the normal had a 4: Hannah Duminske The peas had little to no reaction but the hot did bubble some so we made it a 2. Devon Dubensky The corn had a small reaction if any. The normal bubbled a little so we made it a 2 while the others did not bubble at all. Shayna Dicker

=Light Intensity Activity= We found that if the wavelength is 425 and the brightness is 200 then you reach 100% maximum ATP. Some things that we found strange when the wavelength is at 400 and the intensity is at 200 the ATP increases but the percent stays at 65. We also found that if the light intensity is at 0 and the wavelength is at 750 there is no ATP. Also, when you're maximum ATP or 100% the ATP increases very rapidly. If there is no light intensity there is no ATP no matter the wavelength and the percent stays at 0.

=Primary and Secondary Activity 1= The ecosystems with the more dense plants have a higher productivity than the ecosystems that have less plant vegetation.

Do some plants have a higher productivity than others? Can the productivity in an ecosystem change?

=DNA Lab Questions= > >
 * 1) What are the 5 elements that make up DNA? Hydrogen, oxygen, nitrogen, carbon, and phosphorous.
 * 2) What is the function of DNA from day to day? Controls the functions of cells and constructs other components of cells.
 * 3) Describe how long strands of double-helical DNA fit into the nucleus of a single cheek cell. They are small and bundled together.
 * 4) What was the purpose of using the detergent as a cell lysis solution? It separated the DNA from the cells.
 * 5) Why does the DNA become visible once the alcohol is added? It clumps all the pieces of DNA together.
 * 6) If DNA is so thin, how is it that we are able to see it during this simple lab exercise? It is bundled together from the alcohol.
 * 7) Why is DNA referred to as your genetic fingerprint? It contains the hereditary material.
 * 8) Give some examples of how DNA is used everyday. Investigation crime scene, people getting sick and the DNA is used to see what they have and to trace your ancestry.
