The semicircles are probably the longitude and the latitude, if that what you are talking about.
Answer:
Eubacteria are prokaryotic organisms, as characterized by the lack of a membrane-enclosed nucleus, predominantly unicellular, with DNA in a single circular chromosome, and have peptidoglycan on cell wall when present. They include most of the familiar bacteria of medical and economic importance such as E.
Explanation:
Frogs have smooth, moist skin long, stripy legs and are likely to be found in damp habitats in the garden. and Toads have warty skin, golden eyes and prefer to crawl rather than hop.
A segmented viral genome can facilitate rapid evolution of new viral strains.
Explanation:
The genome of the virus contains both coding and non-coding sequences. Segmented viral genomes are separate unit of nucleic acid in a virion particle and they undergo reassortment.
When the genome of the viral DNA gets segmented, the multiple DNA strands. When two infection with 2 strands of virus takes place simultaneously the two strains may get swapped or cross over. This leads to new strand and hence evolution happens.
examples of such virus are : Birnaviradae, reoviridae
The answer is one of the sandy options i think two but i am not completely sure
