3.08 Marine Science TYPE OF EROSION CONTROL PROS OF USING THIS CONTROL CONS OF USING THIS CONTROL Jetties - Designed to coastal properties. -“The increased wave energy and the sediment trapped behind the seawall often decrease the sediment supply near the seawall‚ causing erosion on adjacent beaches. Therefore‚ alternatives to these hard structures are strongly encouraged and actively sought by the NPS.” Breakwaters -“Dunes not directly disturbed‚ increases area of dry upper beach‚ may allow new

Biofuel Enzyme Kit Katie Adamson Biochemistry Laboratory‚ BIO124L 1/29/15 Abstract The objective in this lab was to determine the effects different conditions had on the enzyme cellobiase. We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this

Digestion Lab Abstract – The purpose of this lab was to understand how different solutions played a role in the digestion protein. By looking at different variables‚ such as temperature‚ and pH we’re capable of understanding just how certain substances functioned and when they didn’t. The data for all labs are clear and concise and give a clear understanding of what solutions work best. All three labs were placed in a warm water bath set at 37’C to stimulate the reaction as if it were taking place

Collision Lab Simulation Purpose: To study elastic and inelastic collisions in one-dimension. Background Information: Momentum: is a measure of mass in motion. It is the product of mass x velocity. Conservation of Momentum: in the absence of external forces‚ such as friction‚ the linear momentum of a system remains constant. Procedure: 1. Open web browser and go to the site: http://phet.colorado.edu 2. Click “play with sims”‚ then “physics”‚ and then “motion” 3. Find the “Collision Lab” 4

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

Bio Lab Report In part II of the Organic Compounds in Foods lab‚ we to examining whether or not the starch in the saltine cracker can chemically break down in sugar with the presence of salivary amylase‚ which is an enzyme found in your mouth which assists in digestion. My group and I were instructed to obtain a saltine cracker from our teacher and chew on it for approximately 2 minutes. After concluding the chewing‚ we then grabbed a beaker and spit our slimy and chewed cracker into it. Subsequently
