Answer:
The DNA is more closer to bacteria.
Explanation:
Mitochondria and chloroplast are considered as semi-autonomous organelle because they contain their own genetic material. The mitochondria and chloroplast evolution can be explained by the endosymbiont theory.
The DNA of mitochondria and chloroplast are more closely related to bacterial chromosome rather than eukaryotic chromosome. Both the organelle and bacterial DNA are double stranded and their translation can be inhibited by the chloramphenicol. Some of their replicating enzymes also show similar characteristics.
Thus, the DNA is more closer to bacteria.
The
infected papaya trees will produce less carbohydrates or chemical energy for the toucan. If there were fewer carbohydrates within each papaya, the
toucan's muscle cells would not be able to obtain as much chemical energy as
they normally do. This chemical energy will be converted into mechanical energy
or heat flow, which the toucan uses to fly.
Therefore, the lower amount
of mechanical energy and heat flow from the muscle contractions, it would
result into a reduced amount of kinetic energy of motion when the toucan is
flying.
Answer:
The evidence suggests that these chloroplast organelles were also once free-living bacteria.
Explanation:
The endosymbiotic event that generated mitochondria must have happened early in the history of eukaryotes, because all eukaryotes have them.

Answer:
Aristotle first wrote about the practice of animal testing in ancient
Greece during the third century BC.
Explanation:
Answer:
The correct option is <em>A) Carry out DNA cloning of the desired sequence into a plasmid vector and then put that into bacteria and wait for the bacteria to copy the gene every time the cells divide.</em>
Explanation:
The DNA can be easily cloned by the help of vectors like plasmids. Plasmids can be described as an extra-chromosomal ring which is present in bacteria. The plasmid has many multiple cloning sites where the desired DNA can be incorporated. the plasmid with the foreign DNA is then incorporated back into a bacterial cell. As bacterial cells like E.coli divide in a short period of time, many copied of our DNA could be obtained whenever the bacterial cell replicates.
