throughout the environment. Many components affect this process such as photosynthesis and cellular respiration. Photosynthesis uses the carbon dioxide that is in the atmosphere to transform it into sugar and oxygen; cellular respiration puts carbon dioxide in the air. Both of these processes were studied during the experiment. In the experiment‚ the tube with both the elodea and the snail had the same level of carbon dioxide in both the light and dark tube. This occurred because the snail performed cellular

Chem-102 Lab Dr. Sobhi Experiment #3: Spectrophotometric Determination of Tartrazine Purpose The objectives of this lab include- illustrating the use of the spectrophotometer in chemical analysis‚ and generating a standard‚ or calibration curve‚ then using that curve to determine the value of an unknown substance. The spectrophotometer is one of the most powerful tools used in chemistry to find the concentration of substances in solution. It compares the colors of a known and an unknown solution

If you are interested in learning the benefits of high intensity interval training‚ your concern with personal fitness is likely greater than the average person’s. High intensity interval training at its most effective level is not for the average Jane or Joe. HIIT‚ as it is also referred to‚ can make even a professional athlete weep. But the results are worth it. High intensity interval training has the advantage of requiring much less time to produce great results. It is designed to achieve rapid

Chlorine in Photosynthesis Experiment Abstract Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place‚ the effect of chlorine in the presence of photosynthesis reactions were studied

community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce over time (Sulaiman et al. 2014). The fermentation of the soy sauce brine revealed that the primary bacteria

Full Lab Report Experiment #2: Acid-Base Titration Lab Description: Acid-Base Titration Introduction In this lab exercise we will evaluate the effectiveness of several indicators for the determination of the point of completion of a specific acid-base neutralization reaction. We will also determine the unknown concentration of the strong base NaOH by its reaction with a known amount of the weak acid‚ potassium acid phtalate (HKC8H4O4‚ abbreviated KHP). This will be accomplished using the titration

plant. Plants and trees cover about thirty percent of the planet’s surface‚ as stated in NASA’s Earth Observatory division. They use a process called photosynthesis‚ which allows plants to take energy from the Sun and later using it as food‚ as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows. First‚ the plant uses the sunlight and the green color in their leaves to make sugar from carbon dioxide‚ or CO2‚ which is in the

Having observed these problems being encountered‚ this project will be developed to bring about the automation of the switching of lighting system using light depending resistor (LDR). The project is an electronic switch that is controlled (turned on and off) by the amount of light shining on the LDR. When light strikes the LDR‚ the switch opens (turns off); when the LDR is in darkness‚ the switch
