Answer;
Mitochondria and chloroplasts contain their own DNA.
Explanation;
-Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell.
-From the Endosymbiotic theory, even though both organelles are found in eukaryotic cells, both mitochondria and chloroplast have characteristics often found in prokaryotic cells. These prokaryotic cell characteristics include: an enclosed double membrane, circular DNA, and bacteria-like ribosomes.

Anatomy During Contraction
-Sarcomere, itself, is shorter
-H-zone is shorter (part of A-band that doesn't have actin filaments in it)
-I-band gets shorter (part of sarcomere lacking myosin)
-A-band stays the same size (zone that contains myosin)
Answer:it's evidence of rapid cooling
And small crystals and rapid cooling
Explanation:
Most organisms in the top levels of an energy pyramid require more food than those on lower levels. On top of this, each level of the pyramid looses energy gained from food. This means that there needs to be more lower leveled organisms for the ones on top to eat in order to gain enough energy. Because of this, there's only enough food for a few of these types of organisms.
I hope this helped! There are probably a few more details you can add, but this is the overall reason :)
