Answer:
Different types of microscopes use different sources for magnification, have different levels of magnification, and can help in visualizing an object in two dimensions or three dimensions.
Thus, if the same object is observed under different microscopes the differences we can observe is the resolution, magnification, and plane (2D or 3D) of the object.
For example, a compound microscope can magnify up to 500x whereas stereoscopic microscope can only magnify up to 50x.

The answers is D option why because when he jumps and goes down with a force and opens parachute so lesser force with his acceleration
Answer:
The correct answer is ''METAPHASE I.''
Explanation:
Metaphase I is the stage in which chromosomal studies are generally performed, because its morphology is very clear. The chromosomes, moved by the mitotic spindle, are placed in the center, between the two asters and form the so-called metaphase plate, in which the chromosomes are positioned in such a way that the kinetochore of each sister chromatid are oriented towards the opposite poles. Keeping chromosomes on the cell equator implies a balance between the forces of the microtubules that tend to move the kinetochores toward opposite poles, so positioning them in the center involves a great deal of energy.In each kinetochore, between 20-30 microtubules can be anchored, which exert traction force towards the pole from which they come, so the metaphase plate is maintained by the balance between the opposite forces of the poles on the chromosomes, which hold their sister chromatids by centromeric cohesin.
Genotype of heterozygous purple plant is: Pp
Cross = Pp × Pp
Offspring: = PP, Pp, Pp, pp
Pp, PP and pp is your answer
:D hope it helps
