Biology Abstract In this experiment we used dried split peas to extract the DNA and observed the protein isolate. Introduction The purpose of the experiment was to learn what the process was to extract DNA. You also learned the characteristics of DNA and go to observe them. Hypothesis I think the DNA will be really interesting to observe. Procedure Material: * Alcohol * Blender * Water * Drinking glasses * Measuring cup * Paper towels * Freezer

Introduction Germination is the very beginning of the plant’s life; where it transitions from being an embryo in a seed to breaking out and becoming a little stem. There are many factors that affect the germination of seeds which include the PH level of the soil‚ the amount of water in its environment‚ the amount of ATP the seed can generate in order to grow‚ the temperature of the environment and the amount of sunlight the seed receives (Ghaderi-Far et al.‚ 2010). The purpose of this study was

GREEN HOUSE EFFECT * The green house effect is the rise in temperature that the earth experiences because certain gases in the atmosphere trap energy from the sun. * Earth receive most of it’s energy‚ called radiation‚ from the Sun sun earth Atmosphere * The Earth’s surface absorbs the solar energy and release it back to the atmosphere as infrared(IR)radiation‚ some of which goes back to space. * IR radiations emitted by the Earth is absorbed by gases in the atmosphere that

Germination in plants is the process in which dormant seed begins to grow and sprout under certain growing conditions. The English pea‚ also known as the garden pea‚ is a member of the legume family and is known to grow roughly three to four inches long. Research shows that it only takes approximately 1 week for the seed to start to germinate. There are many things that can affect‚ the growth of the pea seed such as; temperature‚ moisture‚ planting depth and sunlight. The pea grows best in temperatures

activity of the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less

Enzyme Activators and Inhibitors Lucia House AP Biology‚ Block 4 Mr. Trice October 18‚ 2012 Introduction: Metabolism is the totality of all of an organism’s chemical reactions. Chemical reactions occur due to enzymes‚ a substance which acts as a catalyst in driving chemical reactions in order to produce a desired product (Campbell and Reece‚ 2002). A catalyst is usually a protein; however‚ some catalytic molecules counter this generalization. A discovery made in the early nineteen- nineties

Effects of pH on fungal amylase activity BI 211 November 25‚ 2011 Introduction In recent years‚ the uses of microorganisms have become a huge importance to industry and sparked a large interest into the exploration of enzyme activity in microorganisms. Amylase is one of the most widely used enzyme required for the preparation of fermented foods. Apart from food and starch industries‚ in which demand for them is increasing continuously‚ amylase is also used in

Green Home Essay The growing pollution through greenhouse gasses and the loss of natural beauty‚ rare ecosystems and basic resources have led to the development of two very important designer and construction concepts – green building and sustainable design. The way we build our houses and chose the materials for them can have a great influence on our future and the future of our planet. The role of green houses in modern building is crucial and the process of constructing them must obtain a strong

3 Title: Effect of dissolved Carbon Dioxide on the pH of Water Aim: To investigate the effect of dissolved carbon dioxide on the pH of water. Hypothesis: The dissolved carbon dioxide will cause the water to turn acid‚ lowering the pH when carbon dioxide dissolves in water in which it forms carbonic acid (H2CO3). Materials: Straws‚ distilled water‚ safety glasses‚ pH probe‚ computer‚ universal indicator‚ gloves‚ lab coats‚ measuring cylinder‚ data logger‚ printer‚ pH chart.

The Effect of Soil pH on the Living Conditions In Lumbricus terrestris Abstract The difference in soil pH weighs a heavy measure on the appearance of the earthworm Lumbricus terrestris in different areas of soil. A highly acidic or highly alkaline soil may be the underlying reason for the absence of this earthworm in certain areas where pH plays a large role. In this experiment‚ soil pH was altered with Miracida soil acidifier and Agricultural Limestonea soil correctional for acidic soil
