4. Strain the banana mixture though a cheesecloth, and collect the filtrate in a small beaker. Dispose of the banana residue. 5. Transfer 2 mL of the filtrate to a large test tube.
Strawberry DNA Purpose: To extract DNA from the fruit of a strawberry plant. Background: In this lab we extracted DNA from a strawberry. DNA, or, deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. DNA is located in the nucleus of the cell, and is made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Materials: * Heavy duty zip-lock baggie * 1 strawberry (fresh or frozen and thawed) * Cheesecloth * Funnel * 100 ml beaker * Test Tube * Wooden coffee stirrer * DNA extraction buffer * Ice-cold 95% isopropyl alcohol Hypothesis: DNA can be extracted if you use certain buffers.
Brendan Dennis 2/24/13 CP Biology Enzymes Used vs. Amount of Apple Juice Produced Lab Report Title: Enzymes Used vs. Amount of Apple Juice Produced Problem: How does a change in the enzymes used affect the amount of apple juice produced? Hypothesis: If different enzymes, such as pectinase and cellulase, are used to break down apple sauce, then the most apple juice will be produced when 5 drops of both pectinase and cellulase are used in one mixture because the two enzymes will be working together to break down the apple juice. Procedure: 1.
Experiment & Observation I gathered together my items; distilled water, salt, ruler, scissors, stapler pencil, tape, 16 toothpicks, Kool-Aid drink mix strawberry and grape, set of McCormick food coloring red, yellow, green and blue, small bag of M&M candy, plastic beaker 50 mL, petri dish 60mm, well-plate 24, FDC blue dye #1 0.5 mL vial, FDC blue dye #2 0.5 mL vial FDC red dye #3 0.5 mL vial, FDC red dye #40 0.5 mL vial, FDC yellow dye #5 0.5 mL vial, FDC yellow dye #6 0.5 mL vial, unknown 0.5 mL vial, 3 filter paper chrom 14x7 cm. I first made a solvent using a 50 mL beaker with warm room temperature distilled water and a pinch of salt. I made sure the salt was completely dissolved and set the solvent aside. I took out two of the Chromatography filter paper sheets 14x7 and with a pencil very lightly drew a horizontal line 1 cm from the bottom of both sheet. Then horizontally on the line I just drew I marked off 9 spaces 1.5 cm apart.
Purpose and Hypothesis The pupose of this project is to investigate how the presence of seed crystals changes the growth rate of rock candy. My hypothesis is that seeding the string will affect the growth rate of sugar crystals. Materials 1 quart saucepan 1 glass container with a lid 2 cups of regular table sugar 3/4 measuring cup a few drops of food coloring 1/4 teaspoon of flavoring (such as peppermint, lemon, cherry or strawberry extract)optional 1 thin wooden stick or string ruler tape or plastic wrap Experimental procedure 1.measure 3/4 of water and pour it in sauce pan. Heat on medium high until it comes to a boil. 2.pour 2 cups of sugar in sauce pan and stir.the solution should look cloudy at first then i will become clear .then keep stirring for 2 minutes 3.After the sugar is dissolved pour the solution into the jar.

There are four steps in making the icing. In step one heat the butter, sugar, nuts and ginger over medium heat in a saucepan until a paste is formed. Then in step two spoon the icing evenly onto the cake pan. Next, drain the can of pineapple slices; separate and arrange fruit one layer deep on the bottom of the pan on top of the icing. Finally, place a cherry inside each of the pineapple centers.
Like a tomato, you can know when it is ripe by looking at the color or by squeezing it, the hardness will indicate the ripeness of the fruit. In addition, when I first sliced and opened it, it has an orange color, which looks like a sunset. The smell of persimmons is not aromatic; it does not have an aroma that attracts people to eat it. When it is sliced, however, you can actually smell the fragrance of the fruit spreading in the air. Its smell, in my opinion, is like that of an apricot and mango combined.
Professor Ian Campbell from Australia's Peter MacCallum Cancer Center says that no scientific evidence showing that GM food is harmful to people's health has been presented to date. (Campbell p.4) It illustrates that GM foods are still not unsafe to people. "As long as the GM food comes out in the markets, it means that it has been proved they won’t hurt people’s health," Yunbo Luo states," and GM foods will be digested in our stomachs without changing people’s own genes at all, which is just like other traditional foods." I am for him and some of my classmates as well. We have learned that modern biological technology in high school and got to know the safety of GM foods.
Genetically Modified Foods Genetically modified (Gm) foods are integrated into products that we are not even aware of such as vegetables, fruits, grains, est. GM is a new way for creating foods, therefore scientists do not know ALL of the health and safety risks from eating genetically intergraded foods. The process of producing GM foods is difficult and the failure rate is high. This is why we (my partner and I) feel GM foods should be banned until scientist’s know ALL the affects Gm foods has on humans and the environment. Genetically modified foods use the latest molecular biology techniques and are commonly used for growing crops for human or animal consumption.
