et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light

This lab specifically does not require the knowledge of what each organism does when introduced to another living organism‚ like a human. Figuring out the type of bacteria could help with further experiments. The idea of the unknown bacteria lab is to show

This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon dioxide levels decrease

This lab was completed to determine the rate in which fermentation occurs in different sugars and to compare the rate of cellular respiration in germinating and non-germinating soybeans. Fermentation breaks down sugars for a source of energy. Cellular respiration is the process used by cells to produce energy from nutrients. This process allows sugars and foods to be broke down in order to obtain energy from adenosine triphosphate (ATP). Cellular respiration is vital for survival of cells. Oxygen

franciscana are known to live in high salinity lakes that are often basic (Biology 108 Lab Manual 2015). Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

Tori Suchy Physical Science Honors 1st block October 4‚ 2012 Balloon Powered Car Problem: In order to create a race car that can travel a minimum of eight meters powered by a nine inch balloon. We need incorporate Newton ’s Law of Motion including speed‚ velocity‚ and acceleration. Hypothesis: If a car were to be made out of homemade materials‚ then it would be possible for it to travel 8 meters powered by a nine inch balloon. Independent Variable: building the car from homemade materials

Pixar Facts 1.) In order to give Dash a realistic out-of-breath voice in "The Incredibles‚" director Brad Bird made actor Spencer Fox run laps around the studio.4 2.) Every Friday during the production of “Brave‚” each Pixar employee was told to wear a kilt for the fun of it. 3.) Shortly after completing Toy Story‚ the Pixar chief creative staff of John Lasseter‚ Peter Docter‚ Joe Ranft and Andrew Stanton got together for a lunch meeting at the Hidden City Café in 1994 that would become one of

Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating

Chapter 12 (Part 2) Explain the principle of independent assortment and its relation to meiosis: The segregation of chromosomes in anaphase I of meiosis explains Mendel’s observation that each parent gives one allele for each trait at random to each offspring‚ regardless of whether the allele is expressed. The segregation of chromosomes at random during anaphase I explains Mendel’s observation that factors‚ or genes‚ for different traits are inherited independently of each other. Apply the
