David wants to live more sustainably and use a more environmentally friendly fuel source than the coal he currently uses to heat his home. which choice would be the most sustainable?

Switch from coal to solar power

Explanation:

The choices were:

A. switch from coal to natural gas

B. switch from coal to oil

C. switch from coal to solar power

D. switch to coal with a lower sulfur content

Explanation:

Clean , pure energy is derived from the sun from solar power systems. The installation of solar panels in your home helps to prevent greenhouse gas emissions and reduces our global dependency on fossil fuels. Fossil fuels such as coal and natural gas are the origins of conventional electricity.

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.

if your own plato the answer is b. the fern transitioned from sporophyte generation to gametophyte generation.
