the commercial chitosan. FT-IR spectra gave characteristics bands of –NH2 at 3431cm-1 and carbonyl at 1661cm-1. X-ray diffraction (XRD) patterns also indicated two characteristics crystalline peaks approximately at 10° and 20° (2θ).The surface morphology was examined using scanning electron microscopy (SEM). 4|Page Preparation of Chitosan from Jazan Area Shrimp wastes and Investigation of Its Properties KEY WORDS 5|Page Preparation of Chitosan from Jazan Area Shrimp wastes and Investigation

Paul Jackson November 30‚ 2011 ANT 1010 Michelle Lappegarrd Language of the Neanderthal It is understood that the Neanderthal was an exceptional thinker and communicator; but there are heavy debates that question whether or not it spoke with a language. Some argue that the hyoid bone of the Neanderthal was too high in relation to its larynx to enable its tongue to form words‚ while others argue the opposite. With respect to both theories‚ it was indeed a linguistic hominid. The Neanderthal

then reverting from 3’C to -25’C between the months of July to December. Through those temperatures it causes a cycle of thawing and freezing of the soil. During the short time of the temperature rising‚ the ground thaws out making the soil soggy and wet; but refreezes again in the winter‚ causing the the roots of small plants to tear apart‚ negatively affecting their growth. Abiotic factors such as the cold weather‚ the worn down soil‚ the blistering winds‚ and shorts growing seasons are also reasons

weight 64kDa. Keywords: Phytase‚ Aspergillus fumigatus and Aspergillus terreus. INTRODUCTION Phytase is widespread in nature‚ occurring in plants‚ microorganisms‚ as well as in some animals. Microbial Phytase activity was most frequently detected in fungi. Phytic acid was discovered as early as in 1872 by Pfeffer and a first note on Phytase can be found in the literature in 1907. Phytase belongs to the group of phosphoric monoester hydrolases; it catalyzes the hydrolysis of myo-inositol hexakisphosphate

The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients from the soil. In addition‚ roots often form mycorrhizae with fungi‚ providing further advantage. Some roots are specially designed to store nutrients for later use of the plant. Leaves are wide flat regions that grow off of the stem. Their primary purpose is to add surface area for photosynthesis. 2. List the
