Answer;
-The conservation of "junk DNA" sequences in diverse genomes suggests that they have important functions.
Explanation;
-The term junk DNA refers to regions of DNA that are noncoding. DNA contains instructions (coding) that are used to create proteins in the cell. However, the amount of DNA contained inside each cell is vast and not all of the genetic sequences present within a DNA molecule actually code for a protein.
-Some of this noncoding DNA is used to produce non-coding RNA components such as transfer RNA, regulatory RNA and ribosomal RNA. However, other DNA regions are not transcribed into proteins, nor are they used to produce RNA molecules and their function is unknown.
The first answer is volcanoes
The second answer is They move because of convection currents in the mantle
Immune and reproductive i think
<span>Prokaryotic cells and eukaryotic cells reproduce by mitotic cell division. Regardless of the type of cell, all cells must make a copy of their dna before they divide.</span>
Culturing of microbial organisms allows experts to determine what type of organism is present and at what conditions it abundantly exist. This is an essential tool to determine the cause of contagious/infectious disease so that experts will have a clear understanding how to combat it.
