Review Questions 3. Animals benefit from the relationship with plants because they are able to get rewards such as pollen and nectar. With these they have the ability to continue on with their daily work. Applying Your Knowledge 1. The rise in prominence of one major group does not necessarily result in the total replacement of a previously dominant group because one group may work better in the part than the other group. Gymnosperms for example produce excess amount of pollen‚ they are

and familiarize ourselves with their taxonomic levels through the organism’s mechanisms of feeding‚ motility‚ and reproduction. Our group used the prior knowledge we possessed about the Hydra‚ Rotifer‚ Gammarus‚ and Planaria organisms to complete the lab. We knew that all of these small invertebrates have a freshwater habitat. Each organism differs in taxonomic levels from Genus to Species. We knew that the Hydra reproduces with one of two methods: 1) by “budding” which is an asexual method of reproduction

Siddharth Tirumala Mrs. Kiriazis IB1 Biology 22 August 2013 Diffusion Lab Write-Up Research Question: How does the temperature of the water affect the diffusion of food coloring? Hypothesis: Food coloring will dissolve faster as the temperature of the water increases. Variables: Name of Variable | What is it? | How is it measured? | Units | Range of the data | Independent | Temp. of Water | Thermometer | oC (Celsius) | | Dependent | Rate of diffusion of food coloring | Stopwatch

What are the names of the species used in this experiment? Which of these species was the most tolerant of increased acidity in the aquarium? Which species was the least tolerant? The names of the species used in the experiment were clam‚ dragonfly‚ and side swimmer. The specie that was the most tolerant was the dragonfly and the least tolerant was the clam. Describe how acid precipitation affects ecosystems. Acid precipitation affects the ecosystem‚ for example‚ lowering ph in water when it

chloroplasts 1. This organelle takes sunlight‚ water and carbon dioxide and can make organic food molecules and oxygen. Chloroplast 2. This organelle is constructed of cellulose and supports plant cells and prevents them from blowing up. Cellulos 3. This organelle contains enzymes for intracellular hydrolysis of food molecules. Lysosom 4. This organelle takes in food molecules and oxygen and can transfer the food energy to ATP batteries‚ which will eventually collision energy for chemical reactions

Observance of Artificial Selection: Technical Study of Wisconsin Fast Plants 5th and 6th period AP Biology Due: 12/16/13 Abstract This experiment was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism ’s traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in

Title: studying organisms in an ecological habitat Aim: to determine the feeding relationships in an ecological habitat Method: * Explore ecological habitat * Make notes of features of selected habitat * Measure the seize of the area to be explored * Record the name of all organisms found in the habitat * Make note of any special features of the organisms * Note the presence of any symbiotic relations Observations and results: Tabulation of the organisms in habitat

Also the sunlight beaming on the trees‚ with no water it causes them to die. - ------------------------------------------------------------------------- Question 3 Limestone‚ an underlying material for many soils‚ dissolves and corrodes when exposed to high concentrations of hydrogen ions.

perspective of a measurement could be different than the others‚ but the lab cannot be preformed solo. When it comes to improving the lab‚ there aren’t to many ways to ensure accurate measurements due to the fact that in any experiment there are human and environment variables that cannot be accounted for‚ or even prepared for. In any experiment there will always be human error. Group Lab Report The purpose of this lab is to use a variety of analytical skills and methods to determine the empirical
