Antibiotic resistance happens naturally due to genetic mutation through random selection, however, genetic drift occurs on purpose and tests which genes are stronger and should continue to be passed on to future generations. In most cases, genetic drift is needed and antibiotic resistance isn’t.
Answer:
<u><em>Initiation</em></u>
Explanation:
The first part of translation is initiation. So first an initiator tRNA molecule binds to a start codon in the mRNA. And then more tRNA's with amino acids attach to the mRNA strand according to the codons on the strand. Then the process continues.
Distention from accumulating gas and fluid impede venous return, leading to bowel wall ischemia.
<u>Explanation:</u>
When the bowel lumen is obstructed, the gases and fuids starts accumulating as a repose to the obstruction. The accumulated fluid and gases results in the swelling or enlargement. This will result in the production of electrolytes and water inside the mumen that is in obstruction. The wall of the bowle will also enlarge and becomes swollen.
As more and more fluid and gas gets accumulated in the bowel, the bowel wall will be enlarged and as there is an increase in the pressure due to this accumulation, the fluid starts to leak from the wall. This will enter peritoneum and necrosis. This will result in an acute emergency when it becomes serious.
