The substance needed for cell energy is ATP, which is short form of Adenosine Triphosphate. This is created in the mitochondria, the energy center for the cell. It is created through the process of Cellular Respiration
Answer;
mRNA is synthesized from a strand of DNA
During transcription mRNA is synthesized from a strand of DNA.
Explanation;
Transcription is the process that takes place in the nucleus of a cell, where DNA molecules acts as a primer to synthesis messenger RNA, catalyzed by the enzyme RNA polymerase.
It is the first step of expression of gene, a particular segment of DNA is copied to mRNA by RNA polymerase.
Then the mRNA is transported to the cytoplasm for the process of translation in which proteins are formed.
Pond organisms live in shallow water so they can produce
Accretionary wedge is formed when sediments accreted to the non subducting tectonic plate at a convergent plate boundary. Materials in the accretionary wedge are usually marine sediments that are scrapped off from the down going slabs of oceanic crust. Elevated regions within the ocean basin are transported towards the subduction zones and accreted to the continental margin.
