Explanation:
Spirochetes are distinguished from other bacteria by their general structural features, which are shared by Leptospira. A three- to five-layer outer membrane or envelope surrounds the cell. The flexible, helical peptidoglycan layer and the cytoplasmic membrane are located underneath the outer membrane and protect the cell's cytoplasmic contents. The protoplasmic cylinder refers to the structures that are enclosed by the outer membrane. The flagella of spirochetes are located between the outer membrane and the peptidoglycan layer, which is an uncommon characteristic. Periplasmic flagella are what they're called.
An infection with the spirochete bacteria Leptospira causes leptospirosis. It is disseminated most commonly by direct contact with the urine of sick animals or through contact with urine-contaminated soil or water.
Humans and animals are both affected by leptospirosis, a bacterial illness. It's caused by bacteria from the Leptospira genus. It can produce a wide range of symptoms in people, some of which may be misdiagnosed as other illnesses. Some infected people, on the other hand, may show no signs or symptoms at all.
Britain had claim to Roanoke island because Roanoke Island is one of the three oldest surviving English place-names in the U.S.
Why Britain had claim to Roanoke island?
The Roanoke islands were an attempt by Sir Walter Raleigh to found a permanent settlement in North America with the intention of troubling Spanish shipping, mining for gold and silver, finding a route to the Pacific Ocean, and converting the natives to Christianity.
A permanent English settlement was founded in 1587 when English men, women, and children landed on Roanoke Island. When English ships came back to the island to give supplies only three years later, in 1590, they discovered it abandoned and without any traces of the inhabitants.
Britain had claim to the Roanoke Island colony because the first English settlement in the New World, was founded by English explorer Sir Walter Raleigh.
