rate of photosynthesis using leaf discs. Aim : To measure the effect of light intensity on the rate of photosynthesis in leaf discs. Introduction : The simple concept of photosynthesis is that it can occurs in the presence of light‚ which takes place in the chloroplasts of green plant cells. Photosynthesis can also be defined as the production of simple sugars from carbon dioxide and water causing the release of glucose and oxygen. The chemical equation for photosynthesis can be expressed

HYPOTHESIS Using train conductors as representatives for all of human kind we can postulate with some accuracy the percent of the population of Earth that are complete and total assholes. If you have ever lived in a small town with train tracks running through it you will know that the conductor of the train is required to sound the whistle at every crossing. This is a 4-part whistle; 2 long‚ 1 short‚ 1 long. My hypothesis is that we can calculate what percentage of the population of planet Earth

Practical 5: determination of activation energy of an enzymed catalyzed reaction Introduction: enzymes are complex chemicals that control reactions in living cells. They are biochemical catalysts‚ speeding up reactions that would occur too slowly to be of any usefulness to an organism. Although in organisms‚ it is not necessary for the reactions to be at maximum rate at all times. Enzymes interact with other molecules to produce a stable system in which the products are made when they are

Photosynthesis and Semiconductor-Based Solar Cells Photosynthesis‚ by definition‚ is “the process by which green plants and certain other organisms transform light energy into chemical energy” (photosynthesis‚ 2011). This is a remarkable process that occurs naturally and is one that is required for all living organisms to sustain existence on this planet. The efficiency of this process has sparked inventions‚ such as the semiconductor-based solar cell‚ that would allow humans to produce energy

Cell Respiration In Yeast Abstract This lab investigates the effects of Sucrose concentration on cell respiration in yeast. Yeast produces ethyl alcohol and CO2 as a byproduct of anaerobic cellular respiration‚ so we measured the rate of cellular respiration by the amount of CO2 produced per minute. The results show a trend wherein increased concentrations of sucrose increase the rate of cellular respiration. Introduction All living cells require energy in order to proceed with cellular processes

Have you ever wrote a compare and contrast essay or ever read a compare and contrast essay? Well if not in this essay you will you’ll be reading about how The Truman show and The Giver are similar and different and also what the stories are like and a little about characters The Giver is about to have a perfect community and a perfect world. They all have to wear the same thing and look they all can’t be different so they all see black and white cause they can’t see color casue they all look different

paper with proper formatting and organization. But writing a scientific research paper isn ’t something that you just happen to know. So this is a short guide on how to write one followed by a sample paper written by me last semester for my Intro To Cellular Biology Class at Rensselaer Polytechnic Institute (I got a 98% on it so it should be a good guide). Formatting: Biological research papers should be written in Times New Roman font‚ size 11‚ and a line spacing of 1.5. On the upper right hand

Making the decision to buy or rent a home is one of the most important choices in a person’s life. These are some of the things that should be considered when making this type of decision: what is the five-year plan‚ what are the financial implications of this decision‚ and what type of maintenance are you comfortable with. When deciding to rent or buy‚ a person needs to weigh all options. The price-to-rent ratio is a good first step in the process of deciding to rent or buy a home. The price-to-rent
