To start, move the objective lens to its lowest power setting. Place a slide on the stage with the label side up and the cover slip in the middle. You can only use the coarse focus knob when the power is low. If you can't see anything, move the slide a little while you look and focus. If nothing shows up, turn down the light and move the slide a little while you're looking and focusing. Once you're in focus on low power, move the slide to make the object of interest in the middle of it. Turn the objective to medium power and only change the fine focus. If you need to, turn the objective to high power and only adjust the fine focus.

Answer:
<u>Living things are derived from single units and show several characteristics such as growth respiration, response to stimuli, homeostasis, evolution, and reproduction.</u>
Explanation:
The natural world comprises several biotic or living and abiotic, non-living factors. Cells, are considered the smallest unit capable of supporting life. All living, or biotic factors must be able to grow, carry out respiration- a process that produces energy, and reproduce (pass on genes). They also show some level of organization or complexity, and respond to stimuli. Additionally, living organisms exhibit homeostasis or control over their internal environment and evolve or change over time to adapt to their external environments.
