Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule

placed in an electrophoresis machine. An electric current is run through the machine and the different sized molecules form bands on the gel matrix. In visualization‚ the gel is dyed so the results become present. This is used in modern crime labs‚ figuring out DNA‚ which plays a key role in many criminal trials. The researcher completed this experiment to figure out who committed the murder using gel electrophoresis. The researcher followed five steps in this experiment; First was placing the gel in

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

The major trend is leaning toward the sporophyte dominating the life cycle‚ which means the gametophyte is decreasing. The reason why sporophyte might be dominating

DNA Extraction from Wheat Germ and Making an Agarose Gel AIM: To be able to make and agarose gel and perform gel electrophoresis in six different dyes. Also‚ to extract DNA from wheat germ. INTRODUCTION: Agarose gel is a substance that is used in science for gel electrophoresis and size exclusion chromatography. These processes use agarose gel to separate and analyze proteins and DNA. The medium is composed of a purified agarose powder that has been boiled in a buffer solution and then cooled

Conclusions of DH5α DNA transformation with red colonies resistance to ampicillin and the lacZ gene Introduction: In this experiment‚ a plasmid with a gene that has resistance to the antibiotic ampicillin and has lacZ is used to transfer the resistance into E. coli bacteria in red colonies. This same technique is used to give diabetics their insulin‚ and to give dwarfs growth hormones. The point of this lab is to give the groups an idea how DNA can be transformed

Objective: The purpose of this lab is to allow you to become familiar with a procedure for extracting DNA‚ collecting DNA samples‚ and to observe the physical characteristics of DNA Background: The wild strawberry is a diploid because it only has two sets of chromosomes. While the grocery store kind is an octoploidy because it has eight sets of chromosomes. The reason we chose the grocery store strawberry is because we’d be able to extract more DNA. Ripe strawberries make enzymes which help break

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
