Parts of the microscope are:
1. Eyepiece or ocular. This what you look through at the top of the microscope.
2. Eyepiece tube. Holds the eyepiece in place
3. Objective lens. The primary optical lenses on a microscope ranging from 4x to 100x magnification power.
4. Nosepiece. Houses the objective.
5. Coarse and fine focus knobs. They are used to focus the microscope.
6. Stage. This is a ledge where the specimen to be observed is placed.
7. Stage clips. Clips on the stage that hold e.g. a glass slide on which the specimen has been mounted.
8.Aperture. The hole in the stage through which transmitted light from the base reaches a specimen placed on the stage for observation.
9. Illuminator. This is the light source for a microscope usually located in the base of the microscope.
10. Condensor. Is used to collect and focus the light from the illuminator on to the specimen. It is located immediately under the stage.
11. Iris diaphragm. This is a flexible structure that controls the amount of light reaching the specimen and is located above the condenser and below the stage.
12. Condensor focus knob. Moves the condenser up and down to control the light focus on the specimen.
13. Base. This is the foot of the microscope and supports the whole frame of the microscope.
Climate change is a change in weather that causes disruption of weather patterns, but only if that change lasts for an extended amount of time.

Hope I helped :)
The removal of Balanus shows that the realized niche of Chthamalus is smaller than its fundamental niche. <span>These two species of barnacle do not show competitive exclusion.</span>
Options:
it has a cell wall but lacks a well–defined nucleus and organelles, and its cytoplasm doesn't have
<span>
much structure. - this is the correct one!
It contains a membrane–bound nucleus and organelles, and its organelles have specialized duties. </span>
<span>no!, this is false! prokaryotes don't have membrane-bound nucleus!
It contains a membrane–bound nucleus, a large central vacuole, a cell wall, a cell membrane, and chloroplasts.
- no!, this is false! prokaryotes don't have membrane-bound nucleus!</span>
so, for this we only needed to know that prokaryotes DON'T have a membrane-bound nucleus (and this is also perhaps their most important property)
