Evaporating Dish Aluminum Foil
1,928 wordsPurpose: To conduct experiments and to determine whether they are physical or chemical changes Before we conduct these experiments there are some topics that we must discuss. As I stated in the purpose, in this lab we are going to be looking at some experiments, and we have to determine whether they are a cause of chemical or physical changes. The purpose for all the labs that we will be doing will be the same. During a chemical change a new substance is formed, it is irreversible, and it is usu...

Gel Electrophoresis Restriction Enzymes
554 wordsDNA, Deoxyribonucleic acid, is a double stranded, helical nucleic acid molecule which determines inherited structure of a protein. The steps are made of bases: adenine, guanine, cytosine, and thymine. The sides are sugar and phosphate molecules. Restriction enzymes are enzymes that cut DNA at restriction sites, leaving fragments blunt or sticky. The restriction fragments are separated using a technique called DNA has a negative charge so when an electrical charge is applied it makes DNA move to ...

Cruel And Unusual University Of Pennsylvania
1,089 wordsMany humans use animals for testing each year. Animal testing is when the animals are put through something or injected to see how they react to what medical research they have been used for. There are three very important reasons why animals should not be used for testing harmful or dangerous materials. One of these is that testing and its use is trivial in the cosmetic industry. The second reason is that animals have rights and animals can feel pleasure and pain just as humans do. The third re...

Fruit Flies Fruit Fly
1,462 wordsTo do genetic research on a fruit fly one must understand the life cycle of the fruit fly. Also, to do the research, one must know how to: prepare a vial, subculture, isolate virgins, and make crosses with mutant flies. In addition to doing all of the above, one must know how to identify the differences between male and female fruit flies. Finally, a scientist must know how to keep accurate records of all research. The complete metamorphosis involves four steps. The first step is the egg stage. ...
