Answer:
Recycling saves energy, helps keep materials out of landfills and incinerators, and provides raw materials for the production of new products. It converts organic materials, like food waste and yard trimmings, into a valuable soil amendment that contributes to soil health and keeps organic wastes out of landfills.
Explanation:
Recycling saves energy, helps keep materials out of landfills and incinerators, and provides raw materials for the production of new products. When waste cannot be prevented, recycling is the next best option. Recycling is more than extending the life of landfills. It is about making the best use of the resources we have available and conserving those resources for future generations. It is about conserving water, energy, land and raw materials.
Composting is recycling for organics. It converts organic materials, like food waste and yard trimmings, into a valuable soil amendment that contributes to soil health and keeps organic wastes out of landfills.
Answer:
Explanation:
The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.
In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.
The majority of photosynthesis occurs in the chloroplasts.
Answer:
Guilt, self disgust, senslessness
Explanation:
Boston is plagued by feelings of guilt and self-disgust after the senseless, cold-blooded murder of Gumboot Dhlamini. He wants to know if Tsotsi shares these feelings. Boston asks Tsotsi many questions and this has a profound effect on Tsotsi, who does not remember much of his past.
