Two experiments were performed to investigate the effects of temperature on the growth rate pine seedlings. Experiment 1 A batch of 60 pine seedlings (Batch I) was grown in a greenhouse under controlled temperatures. Ten plants were grown at each of six temperatures from 50 C to 300 C. These plants remained at their original temperatures 24 hours each day for two weeks. All other conditions were the same for all seedlings. The growth rates are shown in Table 1. Table 1. Growth rates for pine

Jessica Martinez Professor Wright Freshman Writing Comp 1 December 5‚ 2013 How to Interpret Dreams You wake up from fighting zombies or playing football in the Super Bowl for your favorite team. Although you’re sad it’s over‚ you wonder what these dreams mean. Most people have wondered this question‚ and few have summed up these dreams to be random and meaningless. Although‚ Dr. G. William Domhoff‚ the author of “The Scientific Study of Dreams” and one of the leading dream researchers in

For this experiment I am investigating how the light intensity as my limiting factor will have in impact on the amount to oxygen produced‚ to should the rate of photosynthesis.Therefore‚ all the controlled variables must remain constant‚ if not there could be an affect on the accuracy of the dependent variable. The CO2 levels are the same for each trial because before placing the sodium hydrogen carbonate i will weigh it with a measuring scale for 1.5 grams. After completing the five measurements

question was “How does exercise affect your breathing and heart rate?” and my hypothesis was “If you exercise then your heart and breathing rates will go up because your body needs more oxygen to be circulated so that your body can keep up.”. My hypothesis was correct‚ as proven by my test. My partner‚ Brian’s heart rate when it was resting was 56 beats per second and his breathing rate was 40 beats per second. We made him do jumping jacks for ten seconds and his heart and breathing rates both went up

The effects of different wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best

What Is Sickle Cell Anemia? Sickle cell anemia (uh-NEE-me-uh) is the most common form of sickle cell disease (SCD). SCD is a serious disorder in which the body makes sickle-shaped red blood cells. “Sickle-shaped” means that the red blood cells are shaped like a crescent. Normal red blood cells are disc-shaped and look like doughnuts without holes in the center. They move easily through your blood vessels. Red blood cells contain an iron-rich protein called hemoglobin (HEE-muh-glow-bin). This protein

different distances. These results show how the rate of photosynthesis and the by-product produced is increased as the intensity of light is increased. The second part of the experiment reveals that the color of light also has an effect of the rate of photosynthesis. The red light resulted in the greatest amount of oxygen produced and the blue was not too far behind. Green produced the lowest amount of oxygen because that is the only color the chlorophyll does not absorb. It also has longer wavelengths

In the Calvin cycle‚ carbon atoms from CO2 are fixed and used to build three-carbon sugars. This process is fueled by‚ and dependent on‚ ATP and NADPH from the light reactions. Unlike the light reactions‚ which take place in the thylakoid membrane‚ the reactions of the Calvin cycle take place in the stroma. In the Calvin cycle‚ getting pulled into the cells using RUBISCO to facilitate the process incorporated gaseous CO2 molecules. RUBISCO acts much like a sponge with a great absorptive power to

HAIER : Taking a Chinese Company Global Overview: Haier Group found in 1984 was a failing refrigerator company when Director Zhang came into force.At that time he did what he will be doing best in the coming years and signed a licensing agreement with German refrigerator company Liebherr. In 1986‚ Haier reached a profit of 1 Mio RMB. Altough there was a huge market demand‚ the company resisted mass production and continued to focus on quality and brand-building instead.The company’s target was

NOTES ON FOOD PRESERVATION & PACKAGING FOR MSc STUDENTS By Prof C S Purushothaman – Feb 2013 HURDLE TECHNOLOGY The spoilage and poisoning of foods by micrnorgenisms is a problem that is not yet under adequate control‚ despite the range of preservation techniques available (e.g. freezing‚ blanching‚ pasteurizing and canning). In fact‚ the current Consumer demand for more natural and fresh-like foods‚ which urges food manufacturers to use only mild preservation techniques (e.g. refrigeration‚ modifed-atmosphere
