Observing Cells George Meni Introduction Did you ever wonder what makes up all living things? Organisms are in most living things, there is a range of organisms from unicellular to multicellular organisms that are inside a human, dog, cat, plant or any living growing thing. An example of a unicellular organism would be; Bacteria, Archaea, Protozoa. An example of a multicellular organism is; most types of Fungi, Algae. There are also organisms that are partly unicellular and multicellular like:

During this lab, we drove to Jim Timmerman’s home in Marco Island, were he happily allowed us to collect and test samples of the water from the mini-reef system he has under his dock. Divided into groups, the whole class measured the temperature, salinity, conductivity, dissolved oxygen, pH, phosphates, ammonia, nitrates, nitrites, and turbidity of the water under the mini-reef system under his dock and compare the results to the water under another neighbor’s dock, who doesn’t have a mini-reef system

The premise of this lab is to measure our enzymatic activity of Alkaline phosphatase, we began measuring our activity by applying different substrate concentration of p-nitrophenyl phosphate in relationship to absorbance over the span of 70 seconds, the data obtained in table 5.1, the different substrate concentration 0.9mM, 0.675mM, 0.45mM, 0.225mM, 0.09mM, 0.045mM, 0.0225mM. keeping our enzyme constant at 100μL, what we concluded is a significant decrease on the absorbance as we decrease the substrate

Kendall Montgomery AP Biology Period 1 The Effect of Varying Light Intensities on the Location Preference of Brine Shrimp Hypothesis: If brine shrimp are placed in a chamber with varying light intensities, then they will prefer a chamber with significant light intensity because they need light in order to hatch and develop. Null Hypothesis: If brine shrimp are placed in a chamber with varying light intensities, then they will not have a preference. Procedure: The brine shrimp were placed in

Cara Williams Professor Straube Biology 107 17 June 2015 Theoretical Experiment Background: According to the World Health Organization, approximately 2.5 million lives would be saved if universal access to safe water and sanitation. According to the United Nations Development Programme, 443 million school days are lost each year due to water-related illnesses. All living things need water to survive. Water is vital for human bodies to preform essential jobs, such as, proper digestion, nutrient

Discussion In order to figure out what family an organism belongs to all the way down to the species, a scientist will perform many tests. Each test done will help to eliminate other bacteria. Once a scientist knows the species, the right steps can be taken to help out people if they get contaminated with the bacteria. When I received my unknown bacteria, I started of doing a Gram Stain. This test revealed to me that I had a Gram negative bacilli in a random arrangement. This step is very important

oxygen and we exhale carbon dioxide. In this lab the topic was about cellular respiration. The lab is to investigate fermentation in respiration. Cellular respiration is a process an organism goes through to obtain energy, ATP [adenosine triphosphate]. Oxygen is then reacted with glucose which results in water, carbon dioxide and ATP. Every organism goes through some type of respiration but only animal cells undergo cellular respiration. For this lab we came up with a question, what environmental

Report on Escherichia Coli and Tetani Clostridium. Tetani Clostridium is responsible for the critical, often lethal, disease Tetanus which is caused by the exotoxin tetanospasmin. Escherichia Coli is a microbe that lives in our gut and can be very helpful to us. Both microbes are bacteria and are rod-shaped bacilli. Both of these microbes have an interesting life cycle, one can help us and both can make us sick, use different life processes and are affected by their environment. Escherichia Coli

Mealworm Response Lab Mealworms are the larvae of the Mealworm Beetle, also known as the Darkling Beetle. The Mealworm Beetle life cycle consists of four stages: the egg, the larvae, the pupa, and the adult. Mealworm beetle eggs are small elongated spheres, about the size of a dime. The eggs hatch anywhere from four to nineteen days after being laid. When the mealworm beetles hatch, mealworm larvae emerge. These larvae feed on plants and dead insects. As these larvae grow, they periodically molt

The mean and standard error was calculated for the 15m and 25m depth, temperature, and salinity. The depth at 15m was 36.7 +/- 7.89 and the depth at 25m was 70.7 +/- 11.3. The temperature at 15m was 23.3 +/- 0.68 and at 25m it was 23.1 +/- 0.59. The salinity at 15m was 28.5 +/- 0.41 and at 25m it was 29 +/- 0.41. There is no significant difference between turtle grass at 15m and 25m (t= 1.667, p= .171). The turtle grass at 15m was .0000 +/- .0000 and at 25m was 20.0 +/- 20.0. There was no significant
