Answer:In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.
Each chromosome has a constriction point called the centromere, which divides the chromosome into two sections, or “arms.” The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can be used to help describe the location of specific genes.

Explanation:
Hello!!
A: Anaphase — 1 chromatids move towards opposite poles. I always remember that “Ana” moves to different places on the sides of town. This is where the chromatids begin to move.
B: Telophase — 4 Cytokinesis may occur. Cytokinesis is the last and final step. The sister chromatids finish moving towards the poles and then cytokinesis occurs.
C: Metaphase — 3 Chromatids line up in the middle of the cell. I always remember since they line up in the middle, they “met” there.
D: Prophase — 2 and 5 Disintegration of the nuclear membrane and the spindle forms. Both of these have to happen first in order for the rest of the processes to occur.
**The order of mitosis goes prophase, prometaphase, Metaphase, Anaphase, Telophase, and Cytokinesis.**
For the bottom:
A: Algae 6 and 10. Both diatoms and kelps (plant related) are a part of the Algae general type.
B: Fungi 7 and 9. Deuteromycetes and Ascomycetes.
C: Protozoa 8. It is ciliates because they are a major group of Protozoa from cilia.
I hope I helped!! Have a great day!! :)
Answer:
Mitochondria have their own cell membranes, just like a prokaryotic cell does. Each mitochondria has its own circular DNA genome.
