Answer:
The ability to bring water into the gills when the mouth is closed would benefit a bottom dwelling shark or ray, because it would allow them to be more discreet when in the process of catching prey and they would be able to stop swimming. Most sharks have to continuously swim or else they would sink, while being able to bring water into the gills when the mouth is closed would highly benefit them and allow them to stop swimming for a moment.
Explanation:
I am not 100% sure this is the correct answer, but I am currently doing a lab on this, so I am using the knowledge I previously had and online resources. I am pretty confident though.
Polypeptide is another name for a protien.
Answer:
Explanation:These studies generally explore how insights gained from traditional unidimensional biodiversity research differ from those derived when multidimensional approaches are taken
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.
