=Cell Size=



__**Explanations:**__
 * Area**-Length x Width
 * Volume**-Length x Width x Height
 * Surface Area to Volume Ratio**-Area divided by Volume
 * Distance of Diffusion**-We measured to distance that the purple penetrated the agar
 * Rate of Diffusion**-Distance of Diffusion divided by the 10 minutes

=Protist Lab:=

Cilia are vibrating hair like substances found on the outside of some organisms. Flagella are slim threadlike structures that help organisms in locomotion. They are kind of a tail like structure. These are different because cilia are on the sides of organisms and vibrate to help with locomotion. Flagella are on the back of the organism and flail back and forth to help move. Cilia are a microtubule-based cytoskeleton.Flagella are made of two central microtubule fibers and nine circular outer microtubule pairs. Other organisms such as humans have cilia also. Cilia in humans are used to catch unwanted particles that enter your body.

The elodea in the salt water was smaller than the elodea without salt water. This is because it is in a hypertonic solution where the water leaves the cells.

=Biomolecules in Foods Lab:=

The biomolecules that are in steel cut oats are starches. This is the only biomolecule found in this food. In cooked rice, we found starches and protein. The protein was one that the entire team thought would be there because we know that eggs are high in protein. In the gelatin, we found starches and protein also. We thought that there would simple sugars in the gelatin because jello is very sugary. =Enzymes Lab:=

=Water Inquiry Lab:=

=Light Intensity Activity:= Are maximum ATP % was reached by using 200 light intensity and 425nm wavelengths. 0-40 light intensity never worked well and the maximum reached in that group 20% ATP. The 80-140 light intensity range worked all right and the maximum reached was 60% ATP produced. The 40-80 light intensity produced a maximum of 40%. As you can see the highest light intensity worked well with a low wavelength but not high wavelengths.

=Primary and Secondary Productivity=

__**Activity #1**__

After analyzing the data table, we have found that places with the most luscious plant life and fertile soil produce the most kilocalories/m2/year. We collected these results by analyzing the table and inferring that the rainforests and plant fields have the highest productivity because they have the highest kilocalories/m2/year.

Questions That We Have:

-Why do these areas have the highest kilocalories/m2/year ? -Why do the deserts have the lowest kilocalories/m2/year ? -Why do the the oceans and lakes have low kilocalories/m2/year ?

=DNA Gatorade Extraction= What are the 5 elements that make up DNA? Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus

What is the function of DNA from day to day? To copy itself and preform the certain tasks that that specific cell is programmed to do.

Describe how long strands of double-helical DNA fit into the nucleus of a single cheek cell. The long strand of double helical DNA fit into the nucleus of a single cheek cell by wrapping around proteins, folding back on itself, and coiling up.

What was the purpose of using the detergent as a cell lysis solution? Dish soap separates food from dishes so it separates the DNA from the Gatorade.

Why does the DNA become visible once the alcohol is added? DNA is a polar molecule and alcohol is a non polar substance so given the info the two will not dissolve into each other

If DNA is so thin, how is it that we are able to see it during this simple lab exercise? We are able to see it during this simple lab exercise because it is present in your spit and even though it is thin, it is present in large amounts.

Why is DNA referred to as your genetic fingerprint? Because each persons DNA is almost exactly the same but in every person there are slight changes that make each persons DNA a little different.

Give some examples of how DNA is used everyday. To solve crimes and determine who committed it, identifying people that have genetic diseases, and tracing your ancestors
