Answer: As in other higher vertebrates, the frog body may be divided into a head, a short neck, and a trunk (see Vertebrates). The flat head contains the brain, mouth, eyes, ears, and nose. A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom.

</span><span><span>A flagella (or flagellum plural) is a long strand like structure that is located in the front end part (more like a tail in front). It flips to the left and right in order for the organism to move. It is connected to the reservoir, which contains the storage of food for the organism.<span>
</span></span>These unicellular organisms are responsible for breaking down materials in the earth. They assist with the decomposition of the dead and decaying matter that can be found on the earth's surface. This break down also makes up natural fertiliser for the plants which then grow up fertilised. These unicellular organisms are also an essential part of the nitrogen cycle. They change the nitrogen from the environment and turn them into absorbable nitrates for the plants, which is an essential part of the plants' food.

It was commonly understood in the past the dogs come from a lineage of wolves, but that isn't the case now. Scientists have found out that dogs and wolves come from a common ancestor about 9,000 to 36,000 years ago. This was done through extensive DNA analysis with samples that took into consideration the geographic locations of their origin and of modern isolation. This yielded a result that despite geographical difference, the dogs are more closely related than to wolves. It is now understood that the complication of the genetic relationship between the two was caused mainly by interbreeding during the course of time, but it isn't just that. Some other factors have come into play including the presence of humans.
