Introduction: This investigation used spectroscopy to evaluate light absorption in different solutions. A spectrophotometer was used in the lab to determine these values. A spectrophotometer is an apparatus used to “measure the absorption of radiation in the visible and UV regions of the spectrum and allows precise at a particular wave length” (Jones et al.‚ 2007). The amount of light absorbed by a substance is directly in relation to the concentration of the solute and also the wavelength moving

Origin of Life 1. The four stages of hypothesis for the origin of life on Earth by chemical evolution is * Abiotic synthesis of small organic molecules * The joining of small molecules into macromolecules * Packaging of these molecules into protobionts * The origin of self replicating molecules that made inheritance possible. 2. A.I. Oparin‚ and J.B.S. Haldane hypothesized a reducing environment. Stanley Miller and Harold Urey did lab experiments that showed that the abiotic

Bruce Yeung 25-11-2012 Biology Lab Comparing and Contrasting Monocots and Dicots Question: In this Investigation‚ live plant specimens of flowering plants would be used to classify plants as monocots or dicots. Hypothesis: Monocots have one embryonic seed leave while Dicots have two. Monocots have one cotyledon in seed while dicots have two. Xylems and Phloem are in circular shape in dicots‚ while monocots’ are scattered. Monocots have the multiples
