Which type of biomass energy is produced from vegetable oils and animal fats? a. ethanol b. methane c. biodiesel d. wood fuels

Biodiesel (D) is made from vegetable oils and animal fats.

 C. biodiesel

Explanation:

Biodiesel is the fuel which is produced from the vegetable oil and animal fat. It consists of esters of long chain alkyl molecules. The fuel is produced by the transesterification reaction in which fats and oils are converted into biodiesel. It is a kind of biomass energy which when burn produce huge amount of heat energy like other conventional fuels. It is a renewable source of energy and does not produce much pollution in the atmosphere.

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 rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
