Answer:
The correct answer will be- Tight junction
Explanation:
The cell membrane contains faces two sides: the faces the lumen of the cell is called the apical membrane while the side which faces the basal side and lateral side is known as a basolateral membrane.
The junctions are present in the layer of cells which allows the physical binding of the cell and also allows the communication between the cells.
Tight junctions are one of the types of junction which helps maintain the polarity of the cell by preventing the diffusion of the integral membrane proteins between the apical side to the basolateral side. This maintains the specialised function of the membrane-like endocytosis in apical membrane while exocytosis at the basal membrane.
Thus, Tight junction is the correct answer.
A hypotonic solution is a solution in which there is a lower concentration in solutes (ex. salt) dissolved in the solvent (ex. water). A hypertonic solution would be one in which there is a higher concentration of solutes in the solvent.

Answer:
Explanation:
There is a lot of missing information in the question but I will help you with the explanation that can help you understand the question and at the end provide a solution to it correctly.
Ion exchange chromatography is necessary and is used for the separation of charged molecules. In this method or process, ionic solutes display reversible electrostatic interactions accompanied by the charged stationary phase, this usually comprises an insoluble matrix together with a covalently attached ion (ion exchanger). The solutes which are introduced in the column, perhaps(- ve) charged, (+ ve) charged, or neutral under a given condition.
So, the higher the charge density, the stronger the interaction.
pI of RNAP= 5.34
The pH of the experimental condition = 7.4
So, if pH is > pI of a solute, the solute gives H+ ion and converts to be (- ve) charged.
Thus, in this scenario (- ve) charged RNAP attaches to the (+ ve) charged ion exchanger. So, an anion exchanger (which is a basic ion exchanger) is imbibed in the separation of the anion in ion exchanger chromatography.
sample of such anion exchanger is DEAE - cellulose (Diethylaminomethyl).
