Answer:

Endoplasmic reticulum is the defective organelle in most CF.

Explanation:

This is because of  mutation(deletion) in the proteins of these organelle. The CFTR  protein -a transmembrane regulator get stucked inside the E.R, thus  the  CFTR chloride protein channel is blocked. Therefore the outflow of Cl and water  out of the cell  is obstructed.

Consequently, the mucus from blocked fluid flow, clogs the lungs, the fallopian tube, sweat duct, and other places.

Answer:

The electron microscope

Explanation:

<u>The microscope that would be best suited to study the inner structure of the chloroplast would be the electron microscope.</u>

<em>The electron microscope has a high magnifying property due to the fact that it uses a beam of accelerated electrons as a source of illumination, unlike the light microscope that uses visible light. While the light microscope might be enough to see the inner portion and the organelles of the cell, the tiny nature of the inner structure of the chloroplast means that the light microscope will not be able to view the details. A more powerful microscope like the electron microscope would be required.</em>

The organism must be regularly associated with the disease and its characteristic lesions

The organism must be isolated from the diseased host and grown in culture

The disease must be reproduced when a pure culture of the organism is introduced into a healthy, susceptible host

The same organism must be re-isolated from the experimentally infected host

In the given hypothesis , Koch's postulates could be used as:

1) identify pathogen associated with disease 2) isolate or purify pathogen 3) test subject gets pathogen 4) same disease/ causes liver disease or not
