Introduction In this experiment‚ I measured the impact of two different topical chemicals on growing bacteria over the course of a week. Bleach‚ water‚ hand sanitizer and hand soap were all variables used to observe the effects of the bacteria swabbed from my palm and fingers. Bleach has been the go to product for killing germs and it is because of the similar effects it has with high temperature on the proteins in bacteria. I hypothesized that bleach would be the most efficient way for killing the

Abstracts The first article I read was about retirement. The article reasserted a lot if not all the points we hit on during the semester. It basically covered three different areas of retirement that need to be looked at seriously. The first being social security‚ which most of us know is looking very dim as far as our generation is concerned. The second was benefit plans offered by employers. And last was the savings that people accumulate until their retirement. The article basically tried

ASU BIO 100 Exam 4 Practice Questions 1. Because of evolutionary descent‚ many species share characteristics with other species to which they are related. Indeed‚ according to evolutionary theory‚ all living species are descended from some common ancestor in the ancient past. What evidence supports this conclusion that ALL living species are related to each other? Shared traits in the fossil record; Genetic Code; DNA Structure of all living organisms 2. For some time‚ Russian prisons have been

Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

"Everyone Is a Mutant‚ But Some More Than Others." Today’s Science. Facts on File News Services‚ July 2011. Web. 19 Sept. 2011. . What do you think about when you hear the word mutant? You probably think about a big‚ alien-type monster with many horrendous attachments‚ or those teenage‚ crime-fighting turtles. The truth is‚ everyone is a mutant. Our bodies all contain mutations. They are what make humans so diverse in terms of attributes. Mutations are changes‚ or mistakes‚ in our genetic code

We only had the potatoes in their solutions for 20 minutes instead of the normal 30 minutes which could mean that the potatoes did not go through the whole process of osmosis. Also‚ a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal

Abstract: Osmosis is the transport of water across a selectively permeable membrane from a region of a higher water chemical potential to a region of lower water chemical potential. (Tzahi 2006) To demonstrate osmosis lab‚ artificial cells were made with various sucrose concentrations and were placed into beakers of different sucrose solutions. Overall the results showed that the higher percentage of concentration gradient of sucrose‚ the more the artificial cells absorbed. Introduction: The
