swell up and eventually burst. This is also the result of osmosis. An ideal environment is one where there is roughly the same number of dissolved particles inside the cell as outside (an isotonic environment). This is the environment that cells are normally found in and have adapted themselves to. In an isotonic environment the amount of water diffusing into a cell equals the amount of water diffusing out. The cell remains the same size and is a happy cell. Hypertonic environments are more common

to the concentration of solutes in a solution (Lab 6-7). There are three stages of tonicity: Isotonic‚ hypertonic and hypotonic. Four unknown solutions were given and labeled as followed: Solution A‚ Solution B‚ Solution C‚ and Solution D. Since potato cells were used for this type of experiment‚ in an Isotonic solution the solute and water concentration are the same as inside the cell in which the isotonic solution contains 0.9% NaCl. In other words‚ water moves in and out in the same amount without

The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs.

Normal saline is regarded as the most appropriate and preferred cleansing solution by health care providers because it is nontoxic‚ isotonic solution that does not damage healing tissue.

Tap water is cost effective and easily available‚ therefore

Osmotic concentrations will either be hypertonic‚ hypotonic or isotonic depending on the results of mass change of the potato tubers.

Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues

cell wall that further protects them. When Gram positive bacteria are treated with lysozyme‚ the lysozyme breaks down the peptidoglycan‚ allowing the cell to rupture if it is in a hypotonic solution or change shape without rupturing if it is in an isotonic solution. The LPS of Gram negative bacteria protects the peptidoglycan from being affected by lysozyme. When Gram negative bacteria is treated with ethylene diamine tetraacetic acid (EDTA)‚ a chelator‚ this destabilizes the LPS allowing it to become
