Answer:
Cells from the pure culture can cause disease in healthy individual after infecting it with the pure culture.
Explanation:
Koch postulates says that microbes are the cause of every disease. These microbes can be isolated from the infected host and can be grown outside the host in a pure culture. Then this pure culture is able to cause disease in a healthy host after infecting the host with pure culture. Then this same microbe can again be isolated from the second host.
So Koch postulates which proves that cells from the pure culture can cause disease in healthy individuals after infecting it with the pure culture was the step that enabled Koch to determine that a particular microbe is the cause of the disease because it was causing disease in healthy individual also.
Unicellular organism: prokaryotic organisms and eukaryotic organisms
Answer:
Arboreal or tree dwelling snakes possess prehensile tails, with which they grip branches as they hunt in the forest canopy. Forest snakes, which live and hunt principally in the trees, use their body muscles and ribs to easily move along branches in the forest canopy.
Explanation:
Around the world, snake populations are in decline because of habitat destruction, disease, over-harvesting, invasive species, and even climate change. These combined threats have brought some snake species ever closer to the brink of extinction.
The widespread disappearance of snakes will be one impact of climate change that some people may find it hard to regret. But as vital predators in sensitive habitats such as rice fields, their decline will have wider ecological consequence, say scientists.
