in place and the chamber lid is closed‚ light from the light bulb passes through it. The detector measures the amount of light transmitted. The white light from the bulb is separated into different wavelengths by reflecting the beam off of a diffraction grating‚ forming a spectrum. A mirror is used to control the angle at which the light is reflected‚ so light of a single wavelength can be passed through the sample. A pigment solution (such as spinach and acetone) is exposed to different wavelengths

Newton’s Laws of Motion and Gravity Define mass‚ weight‚ force‚ and acceleration. Mass – A measure of the total amount of material in a body‚ defined either by the inertial properties of the body or by its gravitational influence on other bodies. It is proportional to‚ but not the same as‚ its mass Force – A quantitative description of the interaction between two physical bodies‚ such as an object and its environment. Force is proportional to acceleration. Acceleration – A vector quantity that

Experiment 2: Starch Hydrolysis by Amylase Theoretical Background Polymers of carbohydrates are called polysaccharides‚ and make up some of the most important naturally occurring compounds [1]. They have thousands of monosaccharide units linked to each other by oxygen bridges. They include starch‚ glycogen‚ and cellulose‚ all three of which yield only glucose when completely hydrolyzed [2].

Chapter 2 REVIEW OF RELATED LITERATURE AND STUDIES Related Literature Spider silk (Parasteatoda tepidarium) commonly known as agiw in Filipino‚is a material spun by varieties of spiders.Spider silk has a unique combination of mechanical strength and elasticity that makes it one of the toughest materials we know.(Arizona State University‚2013). Furthermore‚silk consists of very repetitive blocks of mainly glycine and alanine.These are the simplest and smallest amino acids allowing strands to be packed
