7/30/2015 Assignment [ print page ] Assignment Background Information: Scientists have found that almost all living organisms have a gene that codes for a protein called Cytochrome C. This protein is important in releasing energy from food. Scientists study similarities such as the gene that codes for Cytochrome C in hopes to learn more about the universal genetic code and the relationship between living organisms on Earth. Procedure: The charts below lists a portion of the amino acids found in

Objective: To find out the food substance in food sample X‚Y and Z. Biological Principle: Test for lipids using the grease spot test Test for glucose using Clinistix paper Test for reducing sugars using Benedict’s test Test for starch using the iodine test Test for proteins using Albustix paper Test for vitamin C using DCPIP solution A control using distilled water instead of the sample should be included. Independent: different types of food samples Dependent: different types of food

1. By exhaling out carbon dioxide into the straw on top of the bromothymol blue indicator‚ the solution will turn the color blue into a yellowish-green color. When there is a presence of something that is acidic the BTB indicator changes its color into yellow/green. So in this case‚ the water with BTB and carbon dioxide exhaled into the flask creates a carbonic acid. As an aerobic activity increase than the carbon dioxide rate increases as well. 2. By exercising more‚ one’s body requires more

Iodine is a test for starch while Benedict’s solution is a test for reducing sugars. When solution A is tested by benidicts test‚ the clear blue solution changed to a little reddish and brick red precipitate is formed.this result show that solution A is a reducing sugar. When carried out iodine test with solution A‚ the colourless solution remain unchanged . this tell us that starch is absent is solution A. When solution B is tested with Benedicts test‚ the clear blue solution remain unchanged‚ we

Introduction: Living‚ microscopic‚ unicellular organisms can be identified as microorganisms. Fungi‚ Protista‚ Bacteria‚ and Archaeans are four kingdoms in the phylogenetic tree of life that consist of microorganisms. Amongst these microorganisms the prokaryotes were the first ones to arrive through evolution. The rest of the life forms as we see them evolved from these simple creatures‚ prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of
