Petri Dishes Test Tubes
899 wordsControlled Comparison: During class, our instructor set up the same lab that we were doing with 2 solutions, both of which were known acidic or basic. He placed 2 ml of the known acid into 2 different test tubes, and 2 ml of the known acid into 2 different petri dishes. Then using forceps, he tested blue litmus paper in one petri dish, and red litmus paper in another. The blue litmus paper, after being dipped into the solution, turned red in reaction to the acidic solution. While the red litmus ...

Petri Dishes Bacteria Cells
1,566 wordsIn this lab we observed the growth of bacteria in a conjugation and transformation experiment. We expected the mating plate of the conjunction to grow and the bacteria on the transformation plates to grow also. We also practiced using aseptic techniques to clean the lab benches and to keep the bacteria from being contaminated from outside bacteria. This lab will take a total of 2 days because of the observations that need to be made. The parts of this paper will explain the procedure and the obs...

Dry Ice Petri Dishes
1,905 wordsA particle cloud chamber is a device that makes visible to the human eye the presence of certain particles and cosmic rays. This paper will discuss the process in which a successful chamber prototype was developed. This paper will also discuss how the chamber utilizes the properties of a supersaturated environment to detect these particles. Finally, plans for the future development of a larger model to study the charge and energy of particles through the use of a magnetic field is presented. The...

Gram Negative Petri Dishes
1,384 wordsAbstract/Summary: Changing our focus from the properties and functions that take place within the cell to the actual cell itself, we observed three specific bacterial types within this lab: Gram-positive bacteria, Gram-negative bacteria, and cyanobacteria. We closely observed the features of cyanobacteria and were able to differentiate them from other bacteria. We specifically observed gloeocapsa, merismopedia, anabaena, and oscillator. In addition to this we observed the different characteristi...

Biology Research In Vitro Fertilization
2,054 wordsIn Vitro Fertilization (IVF), is the procedure whereby human babies are conceived, not in the womb but in a test tube or a Petri dish. This procedure has become one of the greatest developments in the world of medical technology. In Vitro Fertilization has given infertile couples the chance to conceive and bear a child from a full term of pregnancy. Without this procedure, their infertility would render them childless. There are many aspects of the IVF program that have been both praised and cri...

Embryonic Stem Cells Petri Dishes
1,229 words... 2 day as compared with uh ES. No significant difference in insulin concentration was observed when incubation's were carried out at 5. 5 -mmol / l medium glucose concentration (15816 gU/ml, gU/ml, n = 6) or at a 25 -mmol / l ambient medium glucose concentration (146. 2 bn 22. 1 gU/ml, n = 6). (Assay et. al. , 2001) Method 2: As a result of their ability to differentiate into many different cell types, one can dissect the complex network of transcription factor genes regulating tissue-specifi...

Morality Of Cloning Vitro Fertilization
1,732 wordsMorality of Cloning Today biological science is rising on a wall of worry. No other science has advanced more during the past several decades or yielded so many palpable improvements in human welfare. Yet none except nuclear physics has aroused greater apprehensions among the general public and leaders in such diverse fields as religion, the humanities, and government. There is much discussion going on about the morality of cloning. It is undecided whether human cloning should be left to individ...

Advantages And Disadvantages Mental And Emotional
1,256 wordsShould Human Cloning be Legal? Cloning captured the publics attention when Scottish scientists startled the world in July of 1996 when they announced the birth of a sheep named Dolly which they had cloned from the nucleus of an adult mammary cell and a sheep egg. Ever since this spectacular event occurred people have been thinking about the possibility of cloning humans. What would a clone be like? His / her physical appearance would be the same as the person he / she was cloned from, but depend...

Sodium Hydroxide Petri Dish
1,559 wordsDetection of Biological Molecules Introduction: Without carbon, nitrogen, hydrogen, sulfur, oxygen and phosphorus, life wouldnt exist. These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to make polymers, which is a long chain of monomers strung together. Biological mole...

Petri Dishes Flowering Plants
3,855 wordsIs there an effect on Rhizobium bacteria by changing its pH? Steve Lincoln Period 3 12 / 7 / 98 Question What are the effects of varying pH levels on Rhizobium bacteria, and can a pH resistant Rhizobium culture be grown? Hypothesis Alterations of the balanced habitat such as the change of pH levels can drastically alter the life of bacteria and can directly affect chemical reactions of enzymes released by the bacteria. Using this information the change in pH will have an effect on the Rhizobium ...

Dopamine Making Neurons Substantia Nigra Spider
367 wordsInsects have sensors (force-sensitive organs) concentrated in areas near joints, tips of the legs, and near exoskeletal sites attached to muscle tendons. These sensors act as strain gauges to detect compression of the exoskeleton. Using this information, insects recognize environments, regulate walking movements, and astonishingly remember stepping patterns and location. Through memory experiments, scientists see that a spider memorizes its own previous walking movements to backtrack to a fly. A...

Lector And Zore June Lector And Zore Petri
636 wordsMyth of The Tornadoes This was the time when gods ruled the universe and used the earth as their playground. The days where perfect for the month of May. The crops of the people grew fast and healthy, and the soil was rich as gold. The gods were being nice this year but people still knew that June was yet to come, the most dreaded month of the year, for this was the month of tornadoes. The people began preparing early for the treachery of the gods and put whatever they could over their windows t...
