The biogeographic regions that are the most likely to have species that show convergent evolution are Nearctic and Palearctic.
<h3>What are Nearctic and Palearctic?</h3>
The Nearctic and Palearctic are two of the eight (8) biogeographic regions present on the Earth planet.
Palearctic represents (in turn) the most widely extended biogeographic region present on the Earth planet.
Biogeographic regions are specific areas consisting of particular biological (biotic components) features.

Answer:old earth:
At its beginning, Earth was unrecognizable from its modern form. At first, it was extremely hot, to the point that the planet likely consisted almost entirely of molten magma. Over the course of a few hundred million years, the planet began to cool and oceans of liquid water formed.The early Earth's atmosphere had a very low concentration of oxygen compared to today. 2.4 billion years ago, the oxygen concentration in the atmosphere was less than one part per billion and the iron concentration in the ocean was much higher than today.At its beginning, Earth was unrecognizable from its modern form. new earth:
"Today's Earth (TE)" is JAXA's land surface & river simulation system developed under the joint research with University of Tokyo. The system distributes & visualizes various hydrological products and their magnitudes for disaster monitoring and hydrological research.
The early Earth was very different from our Earth today. The early Earth experienced frequent impacts from asteroids and meteorites and had much more frequent volcanic eruptions. There was no life on Earth for the first billion years because the atmosphere was not suitable for life.
Explanation:
Answer:
The bacterial DNA gets degraded at step 3 of the viral lytic cycle.
Explanation:
Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.
The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.
After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.
Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.
