  • Cells Case

    Cells Case

    Although a cell may be the smallest functional, living unit known to man; it is certainly not the least important. In fact, all life is based on cells. All functions of an organism are dependent on individual and collective cell functions. Almost all cells have three basic regions which include: the plasma membrane, cytoplasm, and the nucleus; all of which play an active role in cell functions. The plasma membrane acts as an outer boundary for the cell. This boundary is flexible, semi-permeable, and is made to control the passing of molecules in and out

Regardless of whether the solute particles are atoms, ions, or molecules. These colligative properties are vapor pressure lowering, boiling point elevation, freezing-point depression, and osmotic pressure.

  • Comparing Water Potential of Two Plant Tissues

    Comparing Water Potential of Two Plant Tissues

    Comparing water potential of two plant tissues Introduction Osmosis is a passive transport and stands for diffusion of water across the plasma membrane, which is selectively permeable. Taking in account the difference in free water – water not bound to solutes or surfaces – concentration, H2O diffuses from the area of lower solute concentration to the area of higher solute concentration. When plant cells, which have walls, are placed in a hypotonic environment, the wall helps preserve the cell's water balance. Just as in animal cells, the water fills the cell and causes swelling, but

  • Compleximetric Titration

    Compleximetric Titration

    Various compounds or substances can be used in quantitative analysis, including complexes. A complex or coordination compound is a molecular entity composed of a central metal ion reacting with electron-pair donors called ligands. The ligands must have at least one pair of unshared electrons available to form a covalent bond. They can be grouped in different ways depending on the number of coordination bonds they manage to form with the transition metal. Monodentate forms only one coordination bond, while polydentate forms more bonds. Complexes that polydentate ligands form are called chelates. A certain form of

The Cathode ray tube consists of a tube, not unlike a water bottle. Inside this tube were two metal plates. The first was connected to a power source and was positively charged, while the other was connected to the same power source, but was negatively charge and it had a hole in the middle of it. Once the power was fed to the plates, a ray shot out from the negatively charged plate, through

    You might be asking yourself, what entirely is Hydraulic Fracturing? As David Shukman, a writer for the BBC, explains, fracking “is the process of drilling down into the earth before a high-pressure water mixture is directed at the rock to release the gas inside. Water, sand and chemicals are injected into the rock at high pressure which allows the gas to flow out to the head of the well”. In other words, fracking can be seen as a method of drilling down into the earth to extract natural gas. This requiring chemicals and other liquids
