What did you include in your response?

A
The origin of mitochondria and chloroplasts is explained.
B
Both organelles were free-living prokaryotes ingested by primitive eukaryotic cells.
C
Mitochondria and chloroplasts perform aerobic respiration; the host cell provides organic compounds for ATP production.
D
Eukaryotic cells contain mitochondria and chloroplasts, but these organelles function similar to bacterium, which are prokaryotes.
14

Which statement is evidence used to support the endosymbiotic theory?

A
Mitochondria and chloroplasts contain their own DNA.
B
Mitochondria and chloroplasts are surrounded by one membrane.
C
Mitochondria and chloroplasts reproduce similar to eukaryotic cells: through mitosis.
15

Mitochondrial DNA can be taken from bone, hair, or teeth and used in DNA typing. What are the benefits to using mitochondrial DNA over nuclear DNA? Check all that apply.

A
mtDNA requires a much smaller sample than nuclear DNA.
B
mtDNA is useful if the nuclear DNA is degraded.
C
mtDNA is inherited from the mother and father’s egg cells, unlike nuclear DNA.
D
mtDNA is present in all maternal relatives of the person being investigated.
16

Which definition describes endosymbiosis best?

A
a symbiotic relationship in which one organism lives on the other organism and both organisms benefit
B
a symbiotic relationship in which one organism lives inside the other and both organisms benefit
C
a symbiotic relationship in which one organism benefits, while the other organism is harmed
