Black was the darkest and took the longest. Deciding on the percentage of the efficiency of removing the permanent marker using the cream cleanser was difficult as a comparison between each colour needed to be decided upon. Waiting for each marker to dry after 5 minutes was nerve-racking and keeping the same pressure whilst rubbing the sponge over the spots of permanent marker. Based on the findings in this experiment‚ ideas for future experiments would be to observe different variables‚ ensure

Chromatography: Separating Mixtures Introduction: Magic marker inks are often mixtures of several compounds. Paper chromatography is a common method of separating various components of a mixture. After separation‚ you can observe the different colors that make up a particular color of magic marker ink. You can also calculate a ratio Rf‚ which compares how far each compound traveled to how far each solvent (substance that dissolves another substance) traveled during the experiment.

and on the chromosome gives integration. Hfr: a strain with F integrated into the chromosome that will give efficient transfer of Hfr some chromosomal markers. F+ plasmid: 1) Transfers itself at a frequency of 0.1 2) Does not transfer chromosomal markers Hfr Hfr 1) Transfers some chromosomal markers efficiently 2) Other markers transferred inefficiently - Gradient of transfer (It takes about 100 minutes to transfer the entire chromosome) Consider an F+ integrating to make an Hfr:

that genetic markers‚ thought to be wiped clean before birth‚ were used to transmit a single traumatic experience across generations‚ leaving behind traces in the behavior and anatomy of future pups. Studies that show how molecules act as DNA markers that influence how the genome is read are known as epigenetic. We pick up these markers during our lives and in various locations on our body as we develop and interact with our environment. Through a process‚ these epigenetic markers were thought to

the time elapsed. 3.2 Setting up study length 1. We chose 54 m of study length because the traffic stream average speed in front of Polytechnics Sultan Azlan Shah is 60km/h. 2. We used cone as a marker so it will easy to capture the speed limit when the vehicles pass by the marker. 3. Three of our group members were assigned to measure and put the cone at the road. 3.3 Collection of data 1. All of our group members were assigned a different role in this field work.

They have been collecting DNA samples from people‚ and by studying and grouping the genetic markers people possess‚ it can be determined which path your ancestors took when populating the world! It can answer why we ended up where were are‚ and why there is a wide variety of colors and features amongst humans. Now‚ what I am going to be talking

and students are not able to having class without blackboards. Blackboards always accompany students and teachers whole time in school. Blackboards show all the important knowledge in class. It is really hard for teachers to find some chalks and markers soon during teaching. Teachers spend many times on changing screens‚ erasing‚ and organizing blackboards. Students are the direct suffers because blackboards are not convenient. A smarter blackboard may give teachers and students a great success
