Halobacterium Lab Investigation Mason Pirio 12/12/13 Period 5 Table Group 3 PS 2- Experiment Design PS 3- Conclusion Writing PS 13- Nitrogen Cycle Abstract- In this experiment we tested to see how well halobacterium grows in different levels of salinity. We found out that the higher salinity in the growth medium the better the halobacterium grows. Background Information- Halobacterium is a bacteria that is found in the great salt lake. Halobacterium is an extremeophile which means it thrives

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

Ans: The signs and symptoms the young graduate student presented‚ show evidence of Lyme disease. 2. What is the environmental pathway for the vector of this disease? Ans: The environmental pathway for the vector of this disease would be a forested habitat. The black-legged tick or the deer tick is the principle vector of this disease (Lyme

Bacteria are among the oldest species in the world.They both incerease in number and comply with nature very quikly so‚they maintain their species.Therefore‚bacteria have been the most common type of species according to number.Hence‚bacteria had been classified in order to make analysis.easily.Bacteria can be classified into three main categories on the basis of their nurition:saprophytic‚parasitic and chemoautotrophic bacteria. The Saprophytic bacteria are the first type of bacteria

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

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
