AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of

maintain order‚ grow and reproduce. Organisms employ various strategies to capture‚ use and store free energy and other vital resources. Energy deficiencies are not only detrimental to individual organisms; they also can cause disruptions at the population and ecosystem levels. Biological systems must both capture free energy and then transform the energy into usable forms. Autotrophic cells capture free energy through photosynthesis and chemosynthesis. Photosynthesis traps free energy present

Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

Eating fish is labeled as being good for your health; however is farmed fish good for you? More people are opting to eat fish. They have been influenced by reports from the American Heart Association‚ The United States Department of Agriculture and also mass media‚ that eating fish regularly (1 to 2 times a week)‚ may reduce the risk of diseases ranging from asthma and prostate cancer to heart disease. With this increase awareness of healthy benefits of eating fish adds to the trend of fish

I am a fish‚ very small and cute. At one time a long long ago‚ I used to live in the depths of a river but‚ as time passed by‚ my life has changed a lot. This new life that I am spending now‚ is just wonderful‚ and I like it immensely. However‚ life was never hard on me. Even when I lived in the river‚ I was very happy as‚ life there was calm and quiet‚ and I gained a lot of experience there. Going backwards down memory lane‚ I can very clearly recall my life in the river. There‚ in the depth of

Determination of Water Hardness Using a Titrator Heather Crall Chemistry 1 SMT- 271044 10/17/2012 Abstract From seeing all of my results and conclusion I now see that I didn’t understand this lab very well and that its not easy when others try to help. Since I have hard water it tells me that my water flows over and through rocks and minerals‚ like limestone. Purpose The purpose of this lab is to become familiar with the concept of water hardness. We learn that hard water contains high

(Research Labs have space constraints for breeding) 2.)Transparent Embryo that develops outside mother’s womb - Observing organ development at various stages is much easier. 3.) Embryo resembles that of higher vertebrates4.) Rapid Development of Embryo- Experimental data can be collected within a short span of time. | 1.) Water system required- The D.rerio only thrive in water and therefore resources have to be expended

The word “Population Growth” has its origin from the latin words ‘Populus’ meaning people. According to ecological term; “population is group of people of the same species occupying a particular space”. Population is subdivided further into demes or local population which is group of interbreeding organism in demes; they share a common gene pool. Population density is defined as a number of individual per unit area or per unit volume of environment. When the size of the individual is uniform the

not big enough to contain the fish ’s long teeth. The viperfish is also bioluminescent‚ with photophores light-emitting organs on its dorsal fin and along its body to lure its prey to it. The fish has been observed hovering in place in the water with its dorsal fin curved around so that its photophore is waving near its mouth‚ as a means of drawing prey. Because the viperfish ’s body is dark blue or black in color‚ it is thought that other fish can see no part of it other than

CHAPTER 1 INTRODUCTION BACKGROUND OF THE STUDY Fish is abundant in the Philippines and is the cheapest source of protein‚ thanks to advances made in aquaculture or fish farming. Aquaculture is contributing significantly to food security‚ livelihood‚ and the economy. It involves raising seaweeds‚ milkfish‚ tilapia‚ shrimp‚ oysters and mussels in tanks or enclosures‚ ponds‚ pens‚ cages and open coastal waters. Fish Farming has been practiced over a hundred of years. It is a viable‚ sustainable
