Answer:
The wheel and axle is a machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
Answer:
Confocal Microscope is used for cell structures in the micrometer range while Electron microscope is used in the range of nanometers
Explanation:
The confocal microscope makes use of optical sectioning in order to achieve a thin section with the sample still intact. It is used for cells or structures inthe micrometer range such as the lisosomes. The lisosomes in a cell can be tagged with a flourescence dye and they would be seen using the confocal microscope. They provide a high-resolution image with all areas in focus throughout the field of view
The Electron Microscope on the other hand requires real sections, it makes use of transmitted electrons (electrons which are passing through the sample) to create an image. It is used in a range of nanometers, with it, you can view the nanoparticles inside a lisosome.
Answer:
No, the genomic DNA is found only in nucleated cells.

Stamens are the units of androecium which is male reproductive whorl of the flower while pistils are the units of gynoecium which is the female reproductive whorl of the flower.
Each stamen has two parts namely anther and the filament. The anther is present at the top of the filament. pollen grains are produced in the anther.
Good luck!
Anything can come out of that but I think type b might be more possible to happen.
