Answer:
organelles are very similar to present-day bacteria, suggesting a common ancestor.
Explanation:
Some evidence suggests that some organelles like mitochondria and chloroplasts within eukaryotes were once used to be independent eukaryotes.
Endosymbiosis theory says that ancestral prokaryotic cells engulfed bacteria like cyanobacteria which with time evolved into mitochondria and chloroplast. Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.
So these organelles are similar to present-day bacteria showing that they have a common ancestor.
Plants that use photosynthesis would
Answer:
Animals preserve play very important role in maintaining ecosystem biodiversity. In animal preserves, animals are protected from the harmful effects of the changes which occur in the environments due to human intervention. In animal preserves,
animals should be kept in proper environment and provide a proper place for living and food in order to increase the population of the animals.
