Which of the following is evidence of the endosymbiotic theory?
a. eukaryotic cells have dna
b. all the organelles in a cell have their own dna
c. the mitochondria and chloroplast have their own dna
d. mitochondria is only inherited from the mother

c. The mitochondria and chloroplast have their own DNA  

Explanation:

According to the endosymbiotic theory, mitochondria and chloroplasts were prokaryotic organisms that lived freely. These structures were encompassed by eukaryotic cells, which resulted in a symbiotic relationship, in which both parties benefited from the association.

There are some characteristics in mitochondria and chloroplasts that serve as evidence for this theory, one of these evidences is the presence of DNA in these organelles.

Mitochondria and chloroplasts have their own genome. Mitochondrial and chloroplast DNA is circular and without proteins called histones.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
