Question 2

A neurophysiologist was interested in using the path clamp technique. Following statements are related to this technique:

A) Intracellular movement of ion channels.


B) Post-translation modification of the ion channel protein.


C) Ligand that controls the opening or closing of ion channels.


D) Change in current flow in a single ion channel.


Which one of the following combinations will be achievable using the patch clamp technique?

Question 3


The blood plasma proteins (albumin and globulins) from a healthy person were separated by electrophoresis as shown above. The diagnosis of acute inflammation can be done used on one of the following observations:

Question 4

Area of patch 1 is 2000 m2 with a resource density of 5 units/ m2. Area of patch 2 is 3000 m2 with a resource density of 10 units/ m2. As per the theory of ideal-free distribution, organisms distribute themselves such that the expected ratio of abundance of organisms in the two patches (patch 1 : patch 2) is:
