The evidence for endosymbiosis present in eukaryotic cells is associated with the presence of mitochondria and chloroplasts.
<h3>What is the endosymbiosis theory?</h3>
The endosymbiosis theory is a theory in biology that states eukaryotic cells evolved as a consequence of symbiotic relationships between prokaryotes and primitive eukaryotes.
The endosymbiosis theory is supported by mitochondria and chloroplasts, which contain their own genetic material, ribosomes and a similar size when compared to bacteria.
In conclusion, the evidence for endosymbiosis is associated with the presence of mitochondria and chloroplasts.

Spindle fibers form a protein structure that divides the genetic material in a cell. [...] At the beginning of nuclear division, two wheel-shaped protein structures called centrioles position themselves at opposite ends of the cell forming cell poles. Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes called kinetochores. Kinetochores are protein formations that develop on each chromosome around the centromere, which is a region located near the middle of a chromosome. Other microtubules bind to the chromosome arms or extend to the opposite end of the cell. During the cell division phase called metaphase, the microtubules pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the equatorial plane.

He will likely succeed if only his nervousness is at the medium level for this will allow Vance to overcome his task as the medium level is set to overcome medium tasks in which he is on right now with lecturing in having to be nervous of doing or having a mistake.
