what is the extinction coefficient of organic molecules? Molar extinction coefficient, constant for a particular substance, is a measure of the amount of radiation absorbed per unit concentration per unit length and depends upon the wavelength of the incident radiation and is greater where the absorption is more intense.
Why the extinction of bees would end humanity? We may lose all the plants that bees pollinate, all of the animals that eat those plants and so on up the food chain. Which means a world without bees could struggle to sustain the global human population of 7 billion. Our supermarkets would have half the amount of fruit and vegetables.
What would happen to humans if bees went extinct? If all bees died it may not be a total extinction event for humans, but it would be a disaster for our planet. We would see a domino-like effect as many plants started to just disappear one by one, and all animal species would start to struggle to find food.
How long would humanity last without bees? If bees disappeared off the face of the earth, man would only have four years left to live. The line is usually attributed to Einstein, and it seems plausible enough. After all, Einstein knew a lot about science and nature, and bees help us produce food.

what year did megalodons go extinct?
We know that megalodon had become extinct by the end of the Pliocene (2.6 million years ago), when the planet entered a phase of global cooling. Precisely when the last megalodon died is not known, but new evidence suggests that it was at least 3.6 million years ago.
what happens if rhinos go extinct?
They maintain the diverse African grass and woodlands on which countless other species depend. If the rhinos do disappear, the savannahs and forests they call home will become a distinctly different place—in addition to an emptier one. Rhinos share their habitat with a multitude of other plant and animal species.
what was the 95 extinction event?
The Permian extinction was characterized by the elimination of over 95 percent of marine and 70 percent of terrestrial species. In addition, over half of all taxonomic families present at the time disappeared. This event ranks first in severity of the five major extinction episodes that span geologic time.
are engineers extinct?
The Engineers are most definitely not extinct. What David killed in Alien Covenant may not be Engineers at all, but one of their creations. There also exists the possibility that this city was an outpost for rebel Engineers with limited access to technology. This might be the Last Engineer’s “Paradise.”
are we in 6th mass extinction?
The planet has experienced five previous mass extinction events, the last one occurring 65.5 million years ago which wiped out the dinosaurs from existence. Experts now believe we’re in the midst of a sixth mass extinction.
how did the spix macaw get extinct in the wild?
Since the year 2000, the species has been considered extinct in the wild. In addition to illegal trafficking, the destruction of habitat due to human influences was the main reason for the extinction of the species.
how did crocodiles survive extinction?
Crocodiles survived the asteroid strike that wiped out the dinosaurs thanks to their ‘versatile’ and ‘efficient’ body shape, that allowed them to cope with the enormous environmental changes triggered by the impact, according to new research. Crocodiles can thrive in or out of water and live in complete darkness.
are flying squirrels going extinct?
Two subspecies of northern flying squirrel are federally listed as endangered due to habitat loss. Humans have long sought to replicate the flying squirrel’s gliding abilities. Base jumpers and skydivers have developed a special suit that mimics the flying squirrel.
What happens when light passes through dark matter?
Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.
Will cheetahs go extinct?
Cheetahs are listed as “Vulnerable” by the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species, but after a recent study revealed significant population declines, scientists are calling for cheetahs to be uplisted to “Endangered.” In North Africa and Asia, they are considered “ …
Is Paranthropus robustus extinct?
A new fossil discovery in South Africa suggests that Paranthropus robustus, an extinct species that co-existed with early members of our own genus, Homo, may have evolved rapidly during a turbulent period of local climate change about 2 million years ago.
Are flying squirrels endangered in Florida?
While the southern flying squirrels found in Florida are not considered endangered, they are protected from poaching by state law. The poachers in Florida also trafficked other protected animals, like alligators and freshwater turtles.
Are the Engineers immortal?
No they are not, after Dr Elizabeth Shaw tried to re-animate the engineer head retrieved from the pyramid it exploded. Sir Peter Weyland’s quest for immortality was out of the belief that he as a creator could extend the life of his creations.
How much faster are animals going extinct?
Modern extinction rates average around 100 E/MSY. This means birds, mammals and amphibians have been going extinct 100 to 1000 times faster than we would expect.
Is Mount Mauna Loa extinct?
The slow drift of the Pacific Plate will eventually carry the volcano away from the hotspot, and the volcano will thus become extinct within 500,000 to one million years from now. Mauna Loa’s most recent eruption occurred in 1984.
Does dark matter affect the speed of light?
Dark matter does not bend light itself; mass (in this case the mass of the dark matter) bends spacetime. Light follows the curvature of spacetime, resulting in the lensing effect.
Why did David destroy the Engineers?
Shortly after the release of Alien: Covenant, Scott explained that as David learns more about his lineage through humanity and the Engineers, “He hates them. He has no respect for Engineers and no respect for human beings,” and concludes that eradicating them from existence will be for the betterment of the universe.
Does Chloe become an angel in Lucifer?

Can Alpha Raptors be Bola?
Unlike normal Raptors, it’s not immobilized by bolas, so the strategy low-level players usually rely on to escape/kill these creatures is useless against Alphas.
How many species have gone extinct in the Amazon rainforest because of deforestation?
Since the start of the century, the International Union for the Conservation of Nature (IUCN) has declared 665 species either completely extinct or extinct in the wild. Here are four forest-dependent species that have vanished due to habitat loss in the last 20 years.
