Why is it important to focus specimens under the Low Power Objectve before observing it under the High Power Objective?

It allows you to center the specimen, and if it is set up correctly, then when you switch objectives it should still be there and only need fine focusing.
It also reduces the chance of crushing the specimen and/or breaking the slide or the lens as the LPO is further away from the slide than the HPO.

Objectve of hrn in present content?
The traditional objective of a firm is to maximize shareholder wealth. This is mostly done through profit maximisation. This objective is questionable now though as the pursuit of profit can come at the expense of natural resources, the environment, labour standards etc.
What is the objectve of intrenet?
The internet was invented by DARPA largely as a reaction to the cold war. Packet switching would allow information to travel from one place to another even if some of the nodes were missing, due to nuclear war or something. I beat the internet. The end boss is really hard.
