OSHA considers methylene chloride to be a potential occupational carcinogen. Short-term exposures to high concentrations may cause mental confusion, lightheadedness, nausea, vomiting, and headache. Continued exposure may also cause eye and respiratory tract irritation. Exposure to methylene chloride may make symptoms of angina more severe. Skin exposure to liquid methylene chloride may cause irritation or chemical burns. Allegra-D 24 Hour 180 mg / 240 mg (Sanofi-Aventis)
2 3 5 Distinguish Between Active And Passive Transport And R. Movement of materials into and out of cells takes place either passively or actively. Passive movement includes diffusion and osmosis, passive movement requires no energy input from the cell â since the molecules follow a concentration gradient. Active transport requires energy as the molecules are forced against the concentration gradient.
CELLULAR TRANSPORT. The two main types of transport into and out of cells include passive transport and active transport. PASSIVE TRANSPORT involves the transport of molecules from regions of high concentration to regions of low concentration.No energy is used in this process.ELLULAR TRANSPORT.
