organism
Explanation:
<span>The most obvious change due to seasonal variation is the change from summer to winter. Some animals migrate to other parts of the world, such as migratory birds. Many animals in colder climates hibernate. In both cases, the absence of these animals leads to a gap in the ecosystem. In regions with highly seasonal rainfall, the low rainfall season can lead to low flows in rivers, and a reduction of certain habitats for some aquatic organisms, such as beaver or aquatic insects.</span>

Answer is: A nasogastric tube
A nasogastric (NG) tube is used for gastric intubation via the nasal passage, this is a common procedure that provides access to the stomach for diagnostic and therapeutic purposes.
The step is transcription.
<h3><u>Explanation</u>:</h3>
Transcription is the process by which the RNA is produced from ribonucleotide polymerisation taking DNA as the template.
The DNA is the genetic molecule of the living organisms. This DNA stores the genetic information and passes them to the offsprings by means of reproduction. This DNA has the information about the production of the proteins that is manifested by the central dogma theory.
The enzyme DNA dependent RNA polymerase acts on DNA which brings the ribonucleotides and polymerises them according to the complementary template supplied by DNA.
Here the step of transcription are mentioned where we can see a RNA polymerase producing a part of the RNA.
