Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
Well, It would be placed in a hyper tonic solution and will shrink. Hope this helped!

The other three are already well established.
When focusing a specimen you should always start with lower power objective .
<h3>How to use microscope?</h3>
- Lower the stage (the flat ledge on which the slide is situated) to its lowest setting.
- Onto the stage, place the glass slide. Make sure the cover slide doesn't move or break when you push it under the clips.
- Choose an objective lens with the lowest .
- Once the cells are visible, turn the coarse focus knob.power
- When the cells are sharply in focus and visible, steadily turn the finefine focus knob.
- To see the cells more clearly and to repeat steps 1 through 5, use the higher.
- When using the high power objective only the fine adjustment knob should be used.
- The type of microscope used in most science classes is the light microscope.
- You should carry the microscope by the arm .
- The objective are attached to what part of the microscope revolving nosepiece.
