Objectives of the Study This study evaluates the genotoxicity‚ and teratogenicity/antiteratogenicity of the methanol leaf extracts of Tamarindus indica (TE). In particular‚ the study aims to: determine the genotoxicity of TE in terms of: mitotic index chromosomal aberrations micronuclei formation assess the developmental toxicity and teratogenicity potential of TE to zebrafish embryos; and verify the potential of TE to rescue zebrafish embryos from ethanol-induced teratogenicity.

Observing Bacteria Kelli Jo Simco Microbiology Due: 2/8/13 Abstract: Microscopes are fragile instruments that must be handle with extreme caution as they can produce high quality results when observing the smallest specimens on earth. A microscope must be properly cleaned before use and storage. The different objectives allow for a range of observations. At the highest objectives‚ the resolution can easily be lost which is why the oil immersion lens is used to minimize refraction. While

Ben Grygiel Professor Sides ENG-101-D260 1 September 2013 “Observing the Ordinary” Why do people tend to feel attached to “things”? This is a very good question that needs some thought behind it to give you a clear understanding why people feel this way. It’s in our nature to show emotions. If you think about it‚ everything we do in our lives we are showing some sort of emotion or feelings. When I think of people being attached to “things” the first thing that pops in my head is little kids

Observing a Stranger I picked to do my observation of a woman at a park playing with her son. It was on Monday are last day of nice beautiful warm sunny weather we had this week. And the park was packed with lots of children and their mothers. All enjoying themselves before the rain was to return. This woman I observed was about 5ft 2in and about 130lbs. She had long brown hair with some blond and purple strips in it. She was also very tan for this time of year. She was dress in black short and
