Salt is a substance that prevents from osmosis taking place which leads to the seed not receiving any water uptake so it is not able to grow at all since there is no energy provided for its growth. Is a seed able to become tolerant of salt? Quinoa is known to have salt tolerance‚ but it is still shown in this experiment that the quinoa surrounded by distilled water still had much more growth than the quinoa placed with a high concentration of salt. The results were clear that

Lab Report Procedure 6.1: Perform Benedict’s test for reducing sugars. Introduction: Benedict’s tests allows for the detection of the presence of reducing sugars. All monosaccharides are reducing sugars since all of them have active carbonyl group. Some disaccharides that are exposed to a carbonyl group are also reducing sugars but less reactive than monosaccharides. By mixing the sugar solution with Benedict’s solution and heating them‚ a redox reaction will occur. The copper (II) sulphate

Lab Report Density Name: Period: Problem How do you calculate Density? What units did you use for volume‚ mass‚ and density? When the cubes are placed in water which one will sink 1st? What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density? Hypothesis I think the 1st cube was aluminum I think the 2nd cube was steel I think the 3rd cube was brass I think the 4th cube was copper I think the 5th

This lab experiment investigates the effect of listening to different types of music on one’s pulse. The experiment relates the circulatory system to the pulse as it measures how quickly the heart contracts and releases blood. Pulse is measured in beats per minute (bpm). One’s pulse is loudest near the heart‚ because there is more pressure closer to the heart. In contrast‚ one’s pulse is quieter the further away it is measured from the heart‚ because there is less pressure the further the distance

A. Avril Crayfish Lab Report November 9‚ 2012 Dr. Marvin Results: Figure 1. Firing Rate of Tonic Receptor in Response to Stretch. The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential

Instruments: UV/VIS spectroscopy was used to analyze the absorption spectra of the many solutions in this experiment. It was chosen for its ability to collect absorption data quickly and efficiently. A Target Factor Analysis program was used to treat the UV/VIS data collected. Target Factor Analysis was used as the calculation method instead of CLSR due to it taking into account the interference2. Discussion: Table 1 is the calibration matrix

Bath Salts Since synthetic drugs have become a common theme in the news I wanted to look more into “bath salts” otherwise known as synthetic cathinones. The questions I was pondering were: what exactly do these “bath salts” do‚ how is this latest development in drug abuse affecting the brain and how can you treat someone on these dangerous chemicals? I used Google Scholar to research my topic. http://scholar.google.com/scholar?hl=en&q=Minnesota+Bath+Salts&btnG=&as_sdt=1%2C24&as_sdtp=

Purpose The purpose of this experiment was to become familiar with the electrocardiograph to help us determine the electrical activity of the heart. As well as‚ to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread
