F=ma
m=40 kg
a= unknown
f= 400 N
rearrange equation to f/m=a
so (400)/(40) = 10 m/s/s
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.
Answer:
either RNA or DNA
Explanation:
The advancement of biomedical research techniques and molecular biology has led to the observation of the close relationship between certain viruses and some cancers in various animals. Thus, it has been shown that several DNA and RNA viruses are oncogenic in a wide variety of animals, from amphibians to primates, and there is growing evidence that some human cancers have a viral origin.
Based on this, we can conclude that oncogenic viruses can be composed of DNA or RNA.
Explanation:
Marchantiophyta
Bryologists classify liverworts in the division Marchantiophyta. This divisional name is based on the name of the most universally recognized liverwort genus Marchantia. In addition to this taxon-based name, the liverworts are often called Hepaticophyta.
