I believe it is the ascending loop of henle. In the ascending portion, the loop becomes impermeable to water and instead the cells of the loop, actively reabsorb the solute; thus water is not reabsorbed but ions are readily reabsorbed. As the ions are reabsorbed the concentration becomes more and more hypotonic until it reaches 100-150 mOsm/L. Therefore, the ascending loop is called the diluting segment of the nephron due to its ability to dilute the fluid in the loop from 1200 to 100 mOsm/L.

Some substances but not other can cross the (blank) membrane of a cell
Orlov [11]

The correct answer is :

Some substances but not other can cross the (blank ) membrane of a cell. The   blank is to be filled with either cell or plasma. Cell membrane or plasma membrane is the living boundary of a cell which is made of phospholipid. It is a semi-permeable or differentially permeable membrane. It only allows small and non-polar molecules to pass through it. It prevents polar ions or molecules to pass through it

The role of rRNA in gene expression is to?
Verizon [17]

Answer:

The correct answer is rRNA plays an important role during translation (protein synthesis) of mRNA.

Explanation:

Ribosomal RNA or rRNA are the RNA molecules which build up the site for protein synthesis known as ribosomes.

Ribosome synthesis takes place in nucleolus where two types of rRNA molecules associates with proteins, one in large subunit and one in the small subunit to form ribosomes.

These ribosomes physically moves along an mRNA molecule and catalyze the assembly of amino acids where rRNA molecules performs the catalytic steps of protein synthesis that is stitches amino acids together and makes up proteins.

Thus,  rRNA plays an important role during translation (protein synthesis) of mRNA.
