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).
Answer:
The correct answer is option - limbic association area is correctly matched with the sensing of danger.
Explanation:
The limbic association area is found on the medial side of the frontal lobe of the brain. This region or area that helps form memories and converts that to motor responses.
It also helps in the process of emotions and helps in providing the responses according to the particular emotion. Such emotions include fear by sensing danger, it is very important as it helps in interacting socially and expression of the personality and response according to the situations.
Thus, the correct answer is - limbic association area.
The small intestine is the longest part of alimentary canal with a length of 4.5 to 7 m and narrow in width, while the large intestine is the hinder-most part of the alimentary canal with a length of 1.5 m. it called the large intestine because it has a width of 4-6 cm. Also in the large intestine circular folds are absent while its present in the small intestine.
