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.
The basic difference between both kinds of transport is that Active Transport requires chemical energy to complete its biochemical transport as it have to move the molecules from lower concentration towards the high concentration which is against the natural law of transportation and it thus requires energy for this purpose, Whereas passive transport is the transport system which does not require any energy or external force as it is a moment of biochemical from higher concentration towards ...
