Explanation:

The practice of marriage is practised in every culture which is associated with the union of the boy and a girl to which they are committed to spending a life-long relationship.

law: This law mathematically describes how two different bodies in the universe interact with each other.

I hope this is ok :)

What is the objective lens used to locate the specimen and first focus?
Mandarinka [93]
Course alteration is the first to be utilized to find the example, and just with the low power objective. When seeing an example, you should dependably utilize the lower control target focal points first. Low power focal point gives the most stretched out field of view and makes it less demanding to discover the example when you look through the magnifying lens. Finding the example at high power, without first focusing it in the field of view at low power, is almost outlandish.
