Which statement best describes an environmental consequence of unsealed landfills? Landfills can produce carbon dioxide that lea
k into the atmosphere. Long-term exposure to mercury and lead in landfills can cause cancers.
Heavy metals are released as leach ate into surrounding waterways.
Materials in landfills undergo decomposition for hundreds of years.
The correct statement describing environmental consequence of unsealed Landfills is : ( A ) Landfills can produce carbon dioxide that leak into the atmosphere
A landfill is composed of 4 essential components and some are ;
bottom linear
hydrogeologic component and
A cover ( seal )
Given that a landfill constitutes of about 40 to 60 percentof C0₂ the environmental consequence of not providing a proper seal for the landfill will be the leakage of C0₂ into the atmosphere. while
The release of Heavy metals as leach ate into the surrounding can be controlled with the provision of a system in the landfill, materials in landfill undergo decomposition for a long period of time.
Hence we can conclude that Landfills can produce carbon dioxide that leak into the atmosphere.
RNA polymerase, a chemical in the cell, is answerable for making mRNA from the right quality. RNA polymerase is like DNA polymerase, yet it makes a RNA strand as opposed to a DNA strand. The promoter region of DNA Helix is attached by RNA polymerase.
It pulls in nucleotides that supplement those on the DNA strand containing the gene of interest. RNA polymerase duplicates one strand of DNA to make a stretching bit of singlestranded mRNA. RNA polymerase makes the mRNA strand in what is known as the 5' to 3' course.
The effect would be that the green leaves, which contain chloroplasts, containing a chemical called chlorophyll would enable the plants to take in more energy in the form of sunlight, enabling the plants to photosynthesise and grow.
The reticular formation can be said to be a network of nuclei in the brainstem that wakes or alert us to a sharp reaction or occurence at a particular time.
