Properties Of Water Adhesion
How does temperature change affect surface tension?

As the temperature of a liquid increases, its surface tension decreases. When water heats up, the movement of its molecules disrupts the imbalanced forces on the surface of the water and weakens its sheet-like barrier of tightly bound molecules, thereby lowering the surface tension. This is why hot water is more effective when cleaning; its low surface tension allows it to more easily penetrate the fibers of a material like fabric and wash away stains. ( www.classroom.synonym.com)

If I put one cup of water in two different places that are 70 degrees Fahrenheit, and 28 degrees Fahrenheit for twelve minutes, and then switch them, the water’s surface tension will change. I expect the paper to sink after I switch their locations. I am predicting that the paper will sink to the bottom and not float.

My independent variable is one cup of water and my dependent variables are my 70 degree and 28 degrees places.

First, I poured one cup of water into two different cups. The next thing I did was put one of the cups in a place that is 70 degrees Fahrenheit, and the other in a place that is 28 degrees Fahrenheit. I started a timer for twelve minutes after I finished step two. I stuck a piece of paper in both and recorded what happened.Then I switched the location of the two cups. The 70 degrees cup was moved to the 28 degrees place and the 28 degrees cup was moved to the place that is 70 degrees for another twelve minutes.

    Produced by cell clusters in the pancreas called the Islets of Langerhans, insulin is a hormone that regulates glucose concentration in the blood. It is a protein synthesised and stored by beta cells, which secrete it in surges responding to changes in glucose levels. (Hardin, Bertoni and Kleinsmith, 2012) Fig 1.

    2 Production of Protein from Cloned Genes Now that we have covered the basic techniques involved in gene cloning and DNA analysis and examined how these techniques are used in research, we can move on to consider how recombinant DNA technology is being applied in biotechnology. This is not a new subject, although biotechnology has received far more attention during recent years than it ever has in the past. Biotechnology can be defined as the use of biological processes in industry and technology…

    Introduction: Proteins are necklaces of amino acids – long chains molecules. Proteins are the basis of how biology get this done. As enzymes, they are the driving force behind all the biochemical reactions which make biology work. As structural elements, they are main constituents of our bones, muscles, hair, skin, and blood vessels. As antibodies, they recognize invading elements and allow the immune system to get rid of the unwanted invaders. For these reasons, scientists have sequenced the…

    PROTEIN TRANSLATION 1. Initiation Translation To begin translation: large and small ribosomal subunit, along with the initiating tRNA, assembles onto the mRNA 2. Translation Elongation The next amino acyl-tRNA enters the ribosome at the A site The amino acid at the P site is transferred to the tRNA at the A site. The ribosome moves one codon farther along the mRNA, releasing the empty tRNA through the E (exit) site. The A site is free for the next incoming RNA. The cycle is repeated as the…

    Protein SCI/241 Protein A protein are organic compounds that made up of amino acids and are the building blocks of the cells in the body. Every cell in the body requires proteins to grow and repair themselves so these proteins are necessary for a healthy body and survival. Having so much protein can hurt your body so when you consume so much can get you sick and the right size of protein can keep you from getting sick. They’re five types of protein in everything that we eat. The largest class…
