Abstract: Protecting biological diversity is defined based on analyzing the cladistic information. In this lab the null hypothesis was examined through interpreting constructed cladograms. A cladogram of five mammalian species include domestic dog (canis familiaris)‚ the Virginia opossum (Didelphis virginiana)‚ the domestic horse (Equus caballus)‚ the domestic cat (Felis cattus) and the white-tailed deer (Odocoileus virginianusis is generated based on the morphological feathers of these mammalian

What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics‚ by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter‚ particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom‚ as well as the subatomic realm. Really‚ they are two sides of the

Tiration of sulfite in wine using iodine is a common example. Alcohol can be determined by reacting with potassium dichromate. Examples in clinical laboratories are rare‚ since most analyses are for traces‚ yet these titrations

Environmental Chemistry: Water testing in Bouregreg Valley Nowadays we are more and more concerned of environmental issues and especially the ones about water since experts have remarked that wetland regions are disappearing (50% reduction). Wetland regions are very important because they help preserve different wildlife species and also can be considered important indicators of the health of the “blue planet”. One of the most interesting wetland regions is the Bouregreg one that is close to
