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.
1). it either lowers or increases the activation energy. 2). it modifies the rate of the reaction
Meiosis is important in the human life cycle in terms of chromosome number because it maintains the chromosome number in human beings constant. Meiosis occurs when gametes are produced wherein only half the number of the total chromosomes are allotted for each gamete.
