decrease the yield of yeast cells. This statement above is misinforming because antibiotics are used to kill bacteria‚ and yeast are not bacteria. Bacteria are prokaryotic while yeast‚ Saccharomyces cerevesiae‚ is eukaryotic. Yeast is used for fermentation to produce alcohol‚ and as well as to help give bread its shape (formation). Antibiotics have the same effect on both yeast and bacteria although they do not have the same structure. The experiment was carried out to compare the growth of cells

salt solution is 6.3grams and the 15% salt solution is 6.8 grams. My hypothesis was that the carrot would shrink and be very small and gooey‚ but it was wrong. The controlled variable in this lab is the carrot and time‚ the manipulated variable is the salt solution‚ and the resulting variable in this lab is what happens to the carrot. Materials and Methods: . Salt solution ( 0-15%) . 4 Carrot pieces from same Carrot( Cut carrot in half if needed) . 4 Beakers . Water . Triple beam balance

In the humus lab were were trying to find out if hydrogen peroxide would cause a reaction and show us the amount of humus in the soil by putting gas into a graduated cylinder with water to make the water level lower therefore showing us how much humus the material being tested contained. It showed that the sand was lacking humus but the mushroom compost was the most rich in humus. My hypothesis was correct because I predicted that the mushroom compost would produce the greatest amount of humus out

6 November 2012 SUBJECT: Lab Report Analysis This memo proposes the observations and claims I collected from reviewing three different lab reports. Three fields of study are composed within this memo that includes Electrical Engineering‚ Environmental Engineering‚ and Petroleum Engineering. “Electrical Filters‚” (Electrical)‚ written by Joe Schmoe‚ is a lab report made by a student at a university. The College Board produced an environmental lab report named‚ “Monitoring Air Quality‚”

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

Amber McMillian May 26‚ 2009 Bacterial Vaginosis This is a vagina condition also referred to as Gardnerella Vaginitis that can produce vaginal discharge that is a result from an overgrowth of normal bacteria. This will cause a woman to have a vaginal discharge with a foul odor. It is not dangerous but it can cause bad symptoms. If any woman has this problem they should also be checked for more serious infections such as Chlamydia and Gonorrhea. The normal symptoms are excessive vagina discharge

only require small amount of the urine. Usually they are two parts of urine test include. First part‚ visual exam. The sample of urine will be looked for color and cleanness‚ an infection may make urine look cloudy and smell bad. Urine found with blood and foamy can be the signs of kidney problems. Second part‚ dipstick test‚ dipstick is a thin stick with strips chemicals. Strips change color if substance is above normal range.
