Removal of introns and the splicing together of exons.
Introns are regions of the DNA code that do not code for amino acids; therefore, they need to be removed before the mRNA strand is translated. Exons are the parts of the strand that do code for proteins, so they need to be pieced together once the introns are removed.
The tonsils located at the base of the tongue are the lingual tonsils.
He movement of water out of the proximal convoluted tubule follows Na+ by osmosis and is referred to as obligatory water reabsorption.
<h3>What is obligatory water reabsorption?</h3>
Regardless of the body's level of hydration, the term "obligatory water reabsorption" refers to the reabsorption of water in the early parts of the nephron that occurs independently of the antidiuretic hormone (ADH), also known as vasopressin.
<h3>What is osmosis?</h3>
Osmosis is the naturally occurring net movement or diffusion of solvent molecules over a selectively permeable membrane from a location of high water potential to a region of low water potential, in a manner that tends to balance the solute concentrations on the two sides.
