is the snow tiger extinct?

The Cretaceous-Tertiary extinction event, or the K-T event, is the name given to the die-off of the dinosaurs and other species that took place some 65.5 million years ago. For many years, paleontologists believed this event was caused by climate and geological changes that interrupted the dinosaurs’ food supply.
what caused the paleozoic extinction?
Scientists have debated until now what made Earth’s oceans so inhospitable to life that some 96 percent of marine species died off at the end of the Permian period. New research shows the “Great Dying” was caused by global warming that left ocean animals unable to breathe.
how were dinosaur extinct?
Geological evidence indicates that dinosaurs became extinct at the boundary between the Cretaceous and Paleogene eras, about 66 million years ago, at a time when there was worldwide environmental change resulting from the impact of a large celestial object with the Earth and/or from vast volcanic eruptions.
How many snow tigers are left in the world?

Do scientists still believe in dark matter?
By studying how light is distorted by galaxy clusters, astronomers have been able to create a map of dark matter in the universe. A vast majority of the astronomical community today accepts that dark matter exists.
What is an extinction coefficient of protein?
Extinction coefficients for proteins are determined at absorbance maxima near 280 nm. Protein analysis is needed to determine if a sample solution contains the desired protein. For example, measuring the absorbance of a protein sample at 280 nm with a spectrophotometer is a rapid and straightforward method.

How did Tasmanian tiger go extinct?
Scientists believe that Tasmanian tigers were hunted and killed by humans and dingoes, which ultimately led to the Tasmanian tigers’ demise in those areas. Tasmania had few people and no dingoes, though, so it became a last refuge to the Tasmanian tiger and its close cousin, the Tasmanian devil.

What would happen if ants are extinct?
Ants feed on leaves and move large quantities of leaves into their nest. Upon decaying, these leaves turn into vital fertilization for plants near the ant colonies—similarly, ants aid in decomposing dead animals and carcasses. The extinction of ants would result in reduced plant growth due to a lack of nutrients.
