Match the components of MSW landfill to its description. cells

groundwater monitoring

bottom liner

leachate collection system

A system of pipes that collect contaminated water that seeps into the
bottom of a landfill.

They are approved areas for waste disposal.

The landfill part that prevents the contact of buried waste with underlying soils and groundwater.

They are built to test the presence of leachate chemicals in the
groundwater around the landfill.

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

the fossil record provides evidence of a common ancestor to many species.
