Darra Boyer November 18‚ 2015 Affects of Various Drugs on the Heart Rate of Daphnia magna Introduction The Daphnia magna‚ more commonly known as water flea‚ is indigenous to ponds and lakes in northern and western North America. This crustacean has an outer transparent covering called the carapace. The unique physiology of the water flea is useful in translational research allowing researchers to visibly study all of the bodily systems without causing harm to the specimen (2). Being classified

they gave the apple in an evidence bag to the forensic scientist. Then they left and the scientist looked over the apple. She took it out of the bag while wearing gloves‚ and noticed some hairs and/or fibers on it when she looked at it under the microscope.

Ch.2 Essential chemistry for Biology 1. Water is precious to life because living organisms use water as the medium (solvent) for chemical reactions necessary to sustain life. Water also helps maintain temperatures. Droughts are disastrous because they can wipe out crops‚ which in turn cause famine. 2. MATTER: Composed of chemical elements‚ occupies space and has mass (ex: solid‚ liquid‚ and gas states.) CHEMICAL ELEMENTS: substance that cannot be broken down into other substances by chemical reactions

Introduction The annelids (also called "ringed worms")‚ formally called Annelida (from Latin anellus "little ring")‚ are a large phylum of segmented worms‚ with over 2‚000 modern species including ragworms‚ earthworms and leeches. Annelids are abundance in freshwater‚ brackish and marine sediments. They are bilaterally symmetrical‚ triploblastic‚ coelomate organisms. These invertebrates can be recognized by their segmented bodies. Segments each contain elements of such body systems as circulatory

Lab Design “Investigate the effect of a factor on the number of stomata of a leaf.” Research Question: How do differing leaf heights affect the number/density of stomata of a leaf? Hypothesis Stomata are pores‚ typically found under the leaf (lower epidermis)‚ that control the gas exchange of transpiration‚ where water vapor leaves the plants‚ and carbon dioxide enters. I predict that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts
