Lab 1‚ Exercise 1 • Based on the information in Table 2‚ what patterns do you observe? The number of fish that I observed in a body of water increases until the dissolved oxygen was at 12 ppm. After that point‚ the number of fish declines slightly. • Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. When the dissolved oxygen levels increase‚ the number of fish that

Daniel Bergey Lab 2: Proteins and Starches Purpose The purpose of lab 2 and both tests with proteins and starches is to determine which substance contains either protein or starch. Hypothesis Proteins: I predict that any substance I test that derives from a living organism is will test positive proteins. Any substance that isn’t from a living organism more than likely will test negative for proteins. Starches: I predict that any substance that contains any level of glucose will test positive

million Africans were transported to the European colonies in the Americas. Of these‚ over 3.5 million were taken to Brazil. Brazil was the biggest importer of slaves and took in an even greater amount than the United States. What influence did these 3.5 million Africans have on Brazil? The international slave trade that took place from 1538-1888 changed Brazil’s culture profoundly. Many Of Brazil’s cultural identities derive from African descent such as some cuisines and musical rhythms. With an

Lab #2 – Assessment Worksheet Applying Encryption and Hashing Algorithms for Secure Communications Overview In this lab‚ you applied common cryptographic techniques to ensure confidentiality‚ integrity‚ and authentication. You created an MD5sum and SHA1 hash on a simple text file on a Linux virtual machine and compared the hash values of the original files with those generated after the file had been modified. Next‚ you used GnuPG to generate an encryption key pair and encrypted a message

shifts daily. For an example‚ when water freezes into ice‚ or the water in the shower turns to steam. To begin to start describing how a phase shift works we must understand factors that influence a phase transition. Variables that effect a phase shift are volume‚ pressure‚ temperature‚ and number of moles or molecules present in a system. For simplicity when analyzing a system it is easiest to assume that the number

process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate was then subjected to a flammability test to confirm ethanol content. The percent ethanol was computed
