lyudmila [28]

Answer:

Resolution.

Explanation:

This is the ability to  distinguish between two separate  points.  if two  separate points can not be seen separately, but as a single  point,  they can not be resolved.   Consequently Resolution  is the amount of  details of an object that that can be seen. Thus the more  the  higher  the resolution of an object the more  the detail of the object that can be seen.

For example the maxiimum reso;ution of  light microsope is 20nm<u>. Therefore if two objects are placed together more than 20nm apart , they can not be seen(resolved); that is  distinguished from one another by light microscope,This is the limImitation of light microcope.</u>

Electron microscope makes use of beam of electrons for focusing, therefore has resolution than light microscope

Rina8888 [55]

Answer:

Ventilation may increase to compensate for the reduction in gas exchange.

Explanation:

The conducting zone is part of the respiratory system. It includes the organs and structures not directly involved in gas exchange.

It serves as a route for incoming and outgoing air and filtering debris and pathogens from the incoming air.

Blocking the structures of the conducting zone would prevent delivery of air to and from the lungs impairing gas exchange.

In order to compensate for the reduction in gas exchange in the respiratory system, ventilation will increase

The mass of a nucleus is less than the total mass of its nucleons. This difference in mass indicates that some of the mass has b
elena-14-01-66 [18.8K]

Answer:

Option B , Binding Energy

Explanation:

The energy in combining two nucleus is lost in binding them. This binding energy is too large that it causes significant loss of mass and is calculated using the Einstein’s theory of relativity.  

When two nucleons combine , mass defect is caused which leads to loss of mass associated with energy and therefore the mass of nucleus is less than the mass of nucleons.  

Hence, Option B is correct.
