Basing our hypothesis off of this past experiment, I hypothesized that in the presence of ammonium nitrate we should see an increased germination rate of our spores from the Ceratopteris richardii. We grew 2 different cultures of the fern spores, one on a control petri dish and one in 1% NH4NO3, with 6 replicates. They were grown for 4 weeks and were put under sufficient lighting. All the data was compiled from all the replicates and after all the calculations we found that there was a significant difference in the spore germination rate. Less germinated in the presence of 1% ammonium nitrate compared to the spores not in the presence of ammonium nitrate.
Name and describe the function of the five plant hormone groups discussed in your text. 5. Describe sexual and asexual reproduction in flowering plants. Be specific in regards to flowering plants. 1) Monocots are shorts for “Monocotyledons” which means plants whose embryo has one cotyledon; whereas, Eudicots (Eudicotyledons) carry embryo with 2 cotyledons.
Writing Assignment 4 Name: Michael Tran FlyGene Unknown Code: 230 PS ID #:1109766 Lab Section: 16241 BIOL 3311 - Spring 2012 TA Instructor Name: Sneha Koneru Date: March 29, 2012 Materials and Methods In order to contain and cultivate Drosophila melanogaster flies, 25 x 95 mm polypropylene vials are used and are enclosed with foam stoppers. Provisions are made from a dehydrated cornmeal-based formula called 4-24 Blue and is prepared by combination with diluted water. The appropriate ratio of fly food is obtained by measuring half of the provided metal food cup with 4-24 Blue and mixing it with 7 ml of diluted water using a 15 ml conical test tube. Once complete, four granules of dry baker’s yeast are placed on the hydrated food as a nutritional supplement and to prevent the growth of bacteria. To manipulate the flies, they are anesthetized using CO2 that is administered through the FlowBuddyTM device with a 5 L/min flow rate.
Lull Period: The years of calm 1770-1773 Anglo American problems: * Congregationalists and other non-Anglicans were worried by rumors that the Church of England intended to appoint an American bishopric. They feared that the Anglican Church might grow at the expense of their own congregations. * In 1772 Hutchinson revealed that he and the senior Massachusetts judges were to receive their salaries direct from the Crown, payable from the tea duties. Some saw this as evidence of a British design to impose arbitrary rule. * Two events in June 1772 broke the period of quiescence in the quarrel with the mother country.
Felix-Archimede Pouchet, believed in spontaneous generation and published 700 page book which claimed to prove that the life could originate from inanimate matter, thus life from deity. However, Louis Pasteur, convinced the world that disease were caused by microbes and experimented using a “swan-neck” flask, performed at many different environments in different locations, successfully disproved spontaneous generation (creationism) and later his theory became a great influence on modern medicine and public health. Kahn also tried to clarify the difference between creationism and evolution, both based on our religious preference and scientific perspective, and evidence to support both sides of argument. Creationism supports the great creator for existence of this world, from the power of deity and this idea became religious beliefs for many generations for different people. She argues that a scientific theory requires collection of data and
Discuss the criticisms that have been made of any two general defences and consider what proposals have been made for reform of the law. The general defences have evolved over the years mainly through judicial decisions, with which some have received criticism. The defence of insanity has received several criticisms; the first is that rules are not based on medical definitions and the terms used do not relate to medical conditions. Also the rules were created by judges in 1843 and despite huge developments in the understanding, diagnosis and treating of psychiatric illnesses the M’Naughty rules remain unchanged. In 1953, the royal commission on capital punishment described these rules as “obsolete and misleading” and the requirements for “disease of the mind “as “outdated and inaccurate” In the cases of Sullivan, Burgess and Hennessey it appears that this defence is too wide covering epilepsy, sleep walking and diabetes, which most people would not regard as mental illnesses.
In 1967 seventeen Nobel Laureates and 5000 other scientists signed a petition asking for the immediate end to the use of herbicides in Vietnam. Press coverage of the controversial use of herbicides in Vietnam increased in the late 1960s. In 1970 AAAS sent a team of scientists to conduct field tests of the ecological impacts of the herbicide program in Vietnam. In 1969 a report authored by K. Diane Courtney and others found that 2,4,5-T could cause birth defects and still births in mice. This, and follow-up studies, led the US government to restrict the use of 2,4,5-T in the US in April 1970.
One of the criticisms is that the revelation of the genetic predisposition of certain groups to certain ailments could lead to discrimination from health insurance companies. In May of 2006 indigenous representatives went to the United Nations Permanent Forum on Indigenous Issues (UNPFII) to express their frustration, as a result, an investigation was launched into the project. The UNPFII sided with the IPCB and
Michael Pollan's Putting It Back Together Again: "Processed Foods" Initiative 522 on the Ballot 2013 Let's start off with what are GMO's? It's an acronym for the scientific term for Genetically Modified Organism. What is a genetically modified organism, it's anything that as been altered from it's original state. All plant life has it own DNA makeup just like we humans do. When the original or natural organic plant life has been modified they can make crops 4 times larger than a naturally grown crop, they can even modify the plant can be genetically altered to have a pesticide to ward of insects that would normally kill off crops.
The owners of the Suez Canal Great Britain and France both attempted to assault Egypt. Both Britain and France believed that the U.s would come to aid and supply oil for them. The U.S never aided this cause because president Eisenhower did not like the fact that Britain and France kept America out of the assault. The United Nations forced to mantain orders. this assault led to the Oil Embargo in
