How do you kill bacteria?
A commonplace, everyday act of killing bacteria using moist heat is boiling our drinking water.
Iodine is one of the most effective germicidal agents.
It is effective against all kinds of bacteria, as well as spores, fungi and viruses..
Are Sharks older than dinosaurs?
As a group, sharks have been around for at least 420 million years, meaning they have survived four of the “big five” mass extinctions. That makes them older than humanity, older than Mount Everest, older than dinosaurs, older even than trees.
What is the oldest bacteria in the world?
Bacteria: Fossil Record However, one particular group of bacteria, the cyanobacteria or “blue-green algae,” have left a fossil record that extends far back into the Precambrian – the oldest cyanobacteria-like fossils known are nearly 3.5 billion years old, among the oldest fossils currently known.
What is the life span of bacteria?
around 12 hoursBacteria divide somewhere between once every 12 minutes and once every 24 hours. So the average lifespan of a bacterium is around 12 hours or so.
How old is the oldest living organism?
The oldest known living organism is a bristlecone pine that grows in south eastern California’s White Mountains, according to ecologist Christopher Earle’s online database of conifers. A count of the tree’s rings confirms that Methuselah, as the tree is affectionately known, is 4,841 years old.
What was the first animal on earth?
comb jellyThe evolutionary history of the comb jelly has revealed surprising clues about Earth’s first animal. Earth’s first animal was the ocean-drifting comb jelly, not the simple sponge, according to a new find that has shocked scientists who didn’t imagine the earliest critter could be so complex.
What insect lives longest?
queen of termitesThe Longest-lived Insect: The queen of termites, known to live for 50 years.
What is the oldest language in the world?
Chinese: Chinese is the single most spoken language in the world today with around 1.2 billion people wh consider it their first language. The written origins of the language have been traced back to 1250 BC in the late Shang dynasty. Along with Tamil, Chinese is one of the oldest surviving languages in the world.
What is the oldest living organism on earth?
Great Basin Bristlecone pine treeHowever, the oldest, precisely measured organism living on Earth today remains, for now, a Great Basin Bristlecone pine tree. Pando the quaking aspen and Antarctic glass sponges could be much older but their ages are assumed from indirect measurements and educated guesswork.
How do bacteria die?
Most organisms have an intrinsic life span, but bacteria do not. … Bacteria are also killed by many conditions in their environment, the UV in intense sunlight, and they die if deprived of food for long periods of time (but the resistance to starvation varies greatly from species to species).
What animals have the shortest lifespan?
Ephemeral mayflies We often hear that mayflies, like the whiteflies of the Susquehanna River, have the shortest lifespan of any animal on Earth, just 24 hours for many species.
What was before dinosaurs?
At the time all Earth’s land made up a single continent, Pangea. The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo.
What animal has killed the most humans?

What came after dinosaurs?
About 60 million years ago, after ocean dinosaurs went extinct, the sea was a much safer place. Marine reptiles no longer dominated, so there was lots of food around, and birds like penguins had room to evolve and grow. Eventually, penguins morphed into tall, waddling predators.
What was the first thing on earth?
prokaryotesThe first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.
Are bacteria immortal?
Scientists believe the cycle can repeat indefinitely, rendering it potentially immortal. … In fact, bacteria are also said to be biologically immortal, but only at the level of the colony, since the two daughter bacteria resulting from cell division of a parent bacterium can be regarded as unique individuals.] 2.
Who was the first human?
Homo habilisThe First Humans One of the earliest known humans is Homo habilis, or “handy man,” who lived about 2.4 million to 1.4 million years ago in Eastern and Southern Africa.
