DON’T spill any water or have to restart. Make sure no air bubbles are clinging. Then take down final volume of water cylinder. 6. Dump the water out‚ then dry sample off. 7. Repeat this over with the other metal samples. * Hypothesis: * My hypothesis is that even though I will find the densities and names of the unknown metals its not going to be accurate because some water will spill out. Many people are going to come up with the different names because they aren’t care full enough

The lamp experiment is primarily based off of the process of photosynthesis. The experiment tracks the rate of photosynthesis as it is affected by the color of the light source. Changing the light bulb color changes the length of the wavelengths that hit the chloroplasts in the plant leaves and effects how fast or if photosynthesis occurs. The equation for photosynthesis is 6 CO2 + 6H2O + light energy=C6H12O6 + 6O2 meaning that when a plant cell absorbs carbon dioxide and water alongside sunlight

Introduction Photosynthesis takes place in the chloroplast and is the use of sunlight energy for cell processes. It happens through a number of chemical reactions and the transfer of electrons. It is used as the source of energy (ATP) for plants. The reaction equation for photosynthesis is H2O + CO2 + (Light) (CH2O)N + CO2 In the Hill reaction‚ Robert Hill showed how chloroplasts in water can still function if there is light and an electron acceptor to release oxygen. He proved that the oxygen

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

The five-step processes for hypothesis testing are the following. Step1. Specify the null hypothesis H0 and alternative hypothesis H1. The null hypothesis is the hypothesis that the researcher formulates and proceeds to test. If the null hypothesis is rejected after the test‚ the hypothesis to be accepted is called the alternative hypothesis. For example if the researcher wants to compare the average value generated by two different procedures the null hypothesis to be tested is [pic] and

Ecology Lab Report 4/17/12 Abstract Sampling Stomatal Densities of Various Species of Plants The importance of stomata is the fact that they control the intake of carbon dioxide and the loss of water in plants. The ratio of intake to loss creates a better picture of which plants adapt would to their environment and which would not. Eight different plant species were sampled the stomatal densities and compared them to their environments. The densities were recorded for each species

Primordial Soup Hypothesis is a hypothesis created by Alexander Oparin in the year of 1942. It claims that life started when a group of chemicals mixed together to form a pond‚ making amino acids‚ which then lead to proteins‚ and later the first forms of life. The evidence presented in the Miller-Urey experiment provided proof that basic monomers could be created from a mixture of methane‚ ammonia‚ and hydrogen. Different to the Primordial Soup Hypothesis‚ the Iron-Sulfur World Hypothesis states that

Photosynthesis and Semi-Conductor based Solar Cells Plants‚ by shear desire to survive have developed the worlds most efficient and reliable power supply by way of photosynthesis. Scientist for years have tried unsuccessfully to duplicate the process of photosynthesis. However‚ for the purpose of this paper‚ I will compare and contrast how energy and electricity is generated through photosynthesis and a semi-conductor based solar cell. In addition‚ this paper will explain how both processes
