The juxtaglomerular apparatus is a structure (formed by the distal convoluted tubule and the glomerular afferent arteriole) with the function in the regulation of blood pressure and the filtration rate of the glomerulus. Its primary components are:
 · the macula densa- specialized epithelial cells in the distal convoluted tubule (detect Na concentration),
 · juxtaglomerular cells- formed from the smooth muscle cells of the afferent arteriole (secrete renin),
· extraglomerular mesangial cells (lacis cells)-unknown function.

To test the hypothesis that mussels are osmoconformers, researchers exposed mussels to water of varying osmolarities and then dr

inn [45]

The question is incomplete, I included an attachment that completes the question as well as show the options to be chosen from.

Answer: YES, SUPPORTED

Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.

These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.

In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).
