Discussion The result of the experiment determined that water did not spread the fungal spores as well as the low airflow. The fungal spores were spread inefficiently by water compared to that of low airflow. The petri dish 1 and 1a had the same amount of growth, the water seemed to clump the spore the together and deposited them
These plants do not live near the sea normally. Many plants cannot live in soil with high salt content. Salt is called an abiotic factor because it is a non-living factor. Salinity lowers their ability to absorb water and they die. We will experiment to see if beans can be grown in a soil with varying levels of salinity (salt).
Scientific Method Case Study Introduction In this paper I will be identify the five steps of the scientific method and use the method to work through a case study. In the study, I notice the grass in my lawn is short, brown and dead and my neighbors grass is tall, green and alive. I will recognize a problem, develop a hypothesis, design and perform an experiment to test my hypothesis, analyze my data and reach a conclusion, and share my conclusion with the scientific community. First, let us look at scientific method. Scientific Method The American Heritage Dictionary defines scientific method as: “the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to demonstrate the truth or falseness of the hypothesis, and a conclusion that validates or modifies the hypothesis”.
Samantha VanderVeen Mrs. Flegel AP Biology 10 September 2012 Environmental Effects on Isopods In this lab, there was testing of three different environment variables that could affect the lifestyle of an isopod. We used household items such as makeshift tin foil containers, strawberries and potatoes, wet paper towel, a lamp and piece of brown cardstock, along with about 50 isopods to participate in this experiment. Allowing us to determine what kind of environment isopods prefer. We were able to conclude that isopods prefer a dark, damp atmosphere with a large supply of a starchy food source. As a whole, the class was asked to create and carry out at least three environmental differences that would help create and single out variables to help find the most desirable environment for the isopods.
The phosphate activity found in our extract would be acidic because the pH is low. 4. (4pts) Write an abstract for this experiment. An abstract is a short paragraph (three to five sentences) that communicates the purpose of the experiment and states the specific conclusions determined by the experiment. Do not go into detail about the protocol.
This researcher called his experiment" Bound water" "The water of Potato Tissue Potential". (Clemson University by Robert J. Kosinski) Quote: He talked about how, when using organic materials and beakers, there can be predictions made of how sucrose or NaCl molecules will bind up any hydrophilic solute if it is diffusing within a membranous condition. Because the potato is semi permeable , the potato tissue will always take up the water because the water is hypertonic and because it just simply moves into a concentration gradient. (Baumgarten and Feher, 1998; Weiss, 1996, pp. 216-222).
Causes and spread of infections 1 Understanding the cause of infection Bacteria can be both beneficial and pathogenic. These single cell micro-organisms are tiny living beings, neither plant or animal, that normally exist together in millions and reproduce only asexually. Some of their common illnesses and infections include ear infections, food poisoning, urinary tract infections, diphtheria, bacterial meningitis, gastritis and sinusitis. Viruses differ from bacteria, being coated genetic material and in that they do not reproduce on food, needing a living host to do so. They replicate by invading targeted cells of their host and taking over genetic material responsible for reproduction.
That’s why it’s so important to wash your hands or use hand sanitizer, it grows in numerous places. Also bacteria cells do not contain a cell nucleus and rarely harbor membrane-bound organelles, unlike eukaryotes which they all contain a nucleus. Bacteria has a wide range variety of metabolic types and that is how they are defined using their taxonomy, the three different types are phototrophs (sun light), litotrophs (inorganic compounds), and organotrophs (organic compounds). In the lab we tested our very own bacteria off of our tongue and smeared it on a blood agar plate, sheep blood to be exact. We collect the bacteria from the inside of the mouth and grow them in specially prepared petri dishes.
In this experiment the atomic absorption spectrophotometer will be used to analyze the concentration of magnesium in soil samples from different parts of Guam. Soil is very important in agriculture. It is the critical component that gives plants its nutrients to flourish. Atomic absorption spectrophotometer helps identify soils which are contaminated or acidified. This analytical technique helps agriculturist ensure maximum crop production.
For the pH, phosphorous, nitrogen and potassium lab we used the soil test kit to determine the different levels. We filled each comparator with a little soil, distilled water and the powder from the capsule. We shook the comparator until the color of the water changed and recorded the results. DATA: SOIL TEXTURE TABLE SOIL POROSITY TABLE SOIL PERMEABILITY TABLE SOIL pH and NUTRIENTS TABLE ANALYSIS OF RESULTS: From our results, we have discovered that garden soil is mostly made up of silt. Silt is a
