The oak tree fungal pathogen, Phytophthora ramorum, has migrated 800 kilometers in 15 years. West Nile virus spread from New York State to 46 other states in 5 years. The difference in the rate of spread is probably related to the mobility of their hosts
<h3>What is
West Nile virus ?</h3>
West Nile fever is brought on by the single-stranded RNA virus known as the West Nile virus (WNV). It belongs to the same genus as the Zika virus, dengue virus, and yellow fever virus, Flavivirus, and is a member of the family Flaviviridae. Mosquitoes, primarily Culex species, are the main vectors of the virus. Since birds are the major hosts for WNV, the virus continues to spread via a "bird-mosquito-bird" cycle. The virus shares genetic ancestry with the family of viruses that cause Japanese encephalitis.
The virus causes disease symptoms in both humans and horses, and symptoms are hardly seen in other animals. In Uganda, the human sickness was first recognized in 1937, and in the second half of the 20th century, it spread to many other countries.

The waves move toward land. When waves crash into the land over a long time, they can break rock down into smaller pieces. These pieces are called sand. A shoreline is a place where the land and the water meet.
Answer:
Explanation:
A. The bacteria DNA will contain most of the radioactivity. The reason is that the DNA is made up of a sugar phosphate backbone which forms its structural framework. One grinding up the bacteria, the radioactive phosphate will likely react with the DNA.
B. In the second instance, the proteins will contain the radioactivity this is because, the DNA does not have any reaction with sulphur, on the other hand, proteins contain about 3 - 6% sulphur.
