<span>Chromated copper arsenate, or CCA, is a pesticide that has been used for years in
pressure-treating lumber to prevent destruction from rot and insects. Arsenic, a toxic
chemical, can leach from this treated wood, leaving residues on the wood’s surface and in
nearby soil. Young children who play on or near decks or playscapes made from CCA-
treated wood can get arsenic on their skin and into their bodies, especially if they eat or
drink without washing their hands.
Because of the health risks of long-term exposure to arsenic, the Environmental
Protection Agency (EPA) has announced that as of December 31, 2003, arsenic Currently the EPA does not recommend that people remove existing structures made with CCA-treated wood or the soil surrounding those structures. However, they do recommend that people reduce their potential exposure to arsenic.</span>
Cell saps are the liquid inside of a plant cell's large central vacuole, which acts as support in order for it to function. They're made up of amino acids, glucose, salts and water and plays an important role in osmosis.
Cytoplasms, on the other hand, are a jelly-like substance between the cell membrane and nuclear envelope within a eukaryotic cell. They're mostly made up of water and salt, and aid in growth and metabolism in a cell.
Answer: In an ionic bond the valence electrons are transferred from the metal only to the neighboring nonmetal, but in metallic bonding the valence electrons of each atom/ion are free to move or float around within the entire metal solid.
Explanation:
Yes, without homeosatasis a human cannit survive. In order to live we must have a stable internale enviroment
