The collared lizard is a species found in the Desert Southwest. Male collared lizards show considerable color variation‚ ranging from brightly colored to a very dull pattern. The goal is to determine the function‚ if any‚ of male color patterns in collared lizards‚ using the scientific method. The tentative explanation is that male color

Its significance to the individual and society hardly requires any emphasis. In the recent decades population is multiplying by leaps and bounds. This phenomenon is having its impact in every sphere of human life‚ more particularly in the Social and economic life of the society. Significance of demography in different

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
