Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.

Explanation:
Local muscular strength and local muscular endurance are two important qualities of muscle functioning. The maximum weight a muscle can lift is indicated by Local muscular strength while the number of repetitions of particular task a muscle can perform without being exhausted is indicated by local muscular endurance. These both tasks are frequently used in our daily life
For example if you can pull 50 kg weight that would be your local muscle strength and if u can pull it 20 times that would be your local muscle endurance.
While performing the the intensity of resistance exercise during assessment if you pull the 50 kg weight less than 5 times it would be considered as local muscular strength and if you pull it greater than 15 times it would be considered as local muscular endurance.
