Bean Sprouts Experiment Lab Report Research Question (Aim): To determine whether the different amounts of water affect seed germination. Hypothesis: I hypothesize that the largest number of seed germination will occur in the petri dish given 10ml of water. I believe that because, if the plant receives too little water, it will cause the plants to wilt. The plants wilt as they lose water quicker than they gain it from the soil. If the plant collects too much water, it will cause the roots to rot, resulting in the plants not being able to receive enough oxygen from the soil.
Brief Explanation This experiment will test the effect of caffeine on the growth of mung bean plants. By testing this, I can also prove the effect of caffeine on all other organisms. The experiment could go either way: the plants with caffeine could grow more or they could stop growing once I add the caffeine in to the equation. * Independent and Dependent Variables * The independent variables are the watering solutions which are water, caffeine solution, and coffee mixture. The constants are the size of the pot, the concentration of caffeine and coffee, the amount of sunlight, the temperature of the environment (which will remain at room temperature) and the amount of water added daily.
A hypotonic solution is when the substance has lower solutes than its surroundings. During this lab, potato slices are put in 10 cups, 5 of which contain room temperature water, and the other 5 contain a solution of 20% sucrose. The goal is to measure the change in mass of the potato depending on its surroundings. c) Osmosis means that water molecules travel from low solute concentrations to high solute concentrations. This means that the potato that is dropped in water will have an increase in mass.
20061962 Wed The purpose of this study is to test whether or not organic foods have more health benefits and are safer than conventional foods. The word organic refers to how farmers grow and process agricultural products. Farmers use nonconventional methods to fertilize, control weeds and to prevent disease in livestock. This study included seventeen studies in humans which carefully studied the biomarker and nutrient levels in serum, breast milk, semen and urine. The participants involved in this study were tested for pesticide levels.
There are many rules to follow when building structures, removing waste, and even when it comes to farming in all its forms. These rules are implemented to help in lessening pollutants that can be harmful to humans and wildlife alike. Some of the most common pollutants are pesticides, pathogens, oil, and heavy metals. Once these enter our water system, they have the potential to throw our entire ecosystem of kilter. In 1948, Congress enacted the first act regarding the control of water pollution, simply named the Water Pollution Control Act of 1948.
Questions on “The Furbish Lousewort- Weed, Weapon, or Wonder” 1. Macior’s viewpoint is a biocentric viewpoint. He views this plant as valuable due to its life history. Through his studies in his Plant Geography course at the University of Wisconsin-Madison, he first learned of the endemic distribution of Pedicularis Furbishae, or in other words, the fact that it’s species is confined to a small, particular area. In 1977, after discovering that Pedicularis Furbishae was on the endangered status, Macior began working in collaboration with the US Army Corps of Engineers and the Fish and Wildlife services to conduct field and laboratory research with a focus on preserving Pedicularis Furbishae.
If our hypothesis is supported, our results will show that the higher concentration of salt, the faster the enzyme will denature. MATERIALS AND METHODS * 5 mL of potato extract * 10 mL of catechol * 3 mL of .1% salinity concentration * 3 mL of .9% salinity concentration * 3 mL of 2% salinity concentration * 3 mL of 5% salinity concentration * 3 mL of 20% salinity concentration * 1- 5 mL pipettes * Pi-pump for 5 mL pipette * Wax marker * 5 test tubes * Test tube rack My partner and I placed 1 mL of potato extract in five test tubes, along with 2 mL of catechol, to that we added 3 mL of .1% salinity concentration in tube one, 3 mL of .9% salinity concentration in tube two, 2% salinity concentration in tube three, 3 mL of 5% salinity concentration in tube four, and lastly 3 mL of 20% salinity concentration in tube five. Pour each mixture in it’s own spec 20 tube, along with a
Tracy Ramos Mr. Reisinger English 101.11 4 October 2013 Rhetorical Analysis: Exigence: When Rachel Carson’s Silent Spring was published in September 27, 1962, it triggered a storm of disputes over the use of chemical pesticides. Her book helped raise awareness for the environment, warn humans of the dangers of using pesticides such as DDT, preserve several plant and animal species, and make the atmosphere cleaner. Her intent in writing Silent Spring was to warn the public of the dangers related with pesticide use. Throughout her book are countless case studies documenting the harmful effects that chemical pesticides have had on the environment. Along with these facts, she explains how in many occasions the pesticides have done more harm than good in eliminating the pests they were supposed to destroy.
The purpose of this experiment was to investigate on which seeds have the highest germination rate in varying climatic temperatures. In terms of optimal germination temperatures, bean seeds tend to have a higher germination rate at warmer temperatures. Additionally, previous research had shown that “seeds [with similar qualities to bean seeds] stored at 4°C or under dry conditions lost their germination potential immediately” (Zarranz, E. M.). On the other hand, “Pea seeds will germinate as soon as daytime temperatures reach 40°F (4.4°C), although they may take 4-5 weeks to germinate when it's this cold” (www.vegetableexpert.co.uk). Therefore, a
Most of these can be found right in your own kitchen. - Tea Tree Oil - Known for its antifungal properties, undiluted tea tree oil is put on a greased tampon and insert into vagina, let it stay for at least half an hour. To do this twice a day for several days this will eliminate the fungal infection. - Vinegar - not only for cooking, there are credit has antifungal and antibacterial properties. Best thing you can try is apple cider vinegar.
