Explain why the resistance of the current path through the extracellular fluid is much smaller than the resistance of the curren
vodka [1.7K]

Answer:

The correct answer is - the large cross-sectional area and greater length of the cytoplasmic core get less resistance than the smaller cross-sectional area.

Explanation:

The greater length and the large cross-sectional area of the cytoplasmic path or core get less resistance than the resistance of the current path which is the small cross-sectional area of axoplasm. This leads it to greater resistance than the resistance of the current path through the extracellular fluid.

Other than this there is also an unequal distribution of the ions that leads to the increase in potential difference as higher Na+ ions present in cytoplasm and high amount of K+ ion present in axoplasm.

How to write a discussion on macromolecules in a lab report
Kamila [148]
The most common macromolecules found in living organisms are lipids, carbohydrates, proteins and nucleic acids. Briefly, the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy, information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests, many cannot. Scientists then use certain tests to determine the presence of macromolecules. In doing the lab, one was able to determine the characteristics of the given solutions, containing different macromolecules, whilst doing the multiple tests.
