what type of reinforcement schedule is most resistant to extinction? Out of the four types of partial reinforcement schedules, the variable-ratio is the schedule most resistant to extinction.
What caused the saber tooth tiger to be extinct? Scientists theorize that environmental change, decline in prey population, and human activity lead to the death of the saber-tooth tiger some 10,000 years ago.
When did the saber tooth go extinct? It went extinct about 10,000 years ago. Fossils have been found all over North America and Europe. Smilodon fossils from the La Brea tar pits include bones that show evidence of serious crushing or fracture injuries, or crippling arthritis and other degenerative diseases.
How old is Alethopteris? Alethopteris is a prehistoric plant genus of fossil Pteridospermatophyta (seed ferns) that developed in the Carboniferous period (around 360 to 300 million years ago).

what type of reinforcement schedule is most resistant to extinction? – Similar Questions
can a solar flare cause a mass extinction?
large solar cosmic ray events were a primary cause of the Pleistocene megafaunal extinction. produced radiation levels at the Earth’s surface fatal for unprotected mammalian species.
why did the megalodon became extinct?
The cooling of the planet may have contributed to the extinction of the megalodon in a number of ways. As the adult sharks were dependent on tropical waters, the drop in ocean temperatures likely resulted in a significant loss of habitat.
what animals survived mass extinction?
Birds: Birds are the only dinosaurs to survive the mass extinction event 65 million years ago. Frogs & Salamanders: These seemingly delicate amphibians survived the extinction that wiped out larger animals. Lizards: These reptiles, distant relatives of dinosaurs, survived the extinction.
how did smilodon go extinct?
Smilodon died out at the same time that most North and South American megafauna disappeared, about 10,000 years ago. Its reliance on large animals has been proposed as the cause of its extinction, along with climate change and competition with other species, but the exact cause is unknown.
when did giant moa became extinct?
It is hard to know exactly when the last of New Zealand’s iconic giant birds kicked the proverbial bucket, but new research has come up with the most accurate guess to date. Moa likely became extinct sometime between 1440-1445 AD, according to a new study from University of Auckland and Landcare Research scientists.
did humans cause the extinction of animals in australia?
New international research led by Monash University has found that humans – and not climate – caused Australia’s Pleistocene megafaunal extinction.
does a meteor collision cause mass extinction?
A large asteroid or comet could collide with the Earth’s surface with the force of hundreds to thousands of times the force of all the nuclear bombs on the Earth. For example, the K/T boundary impact has been proposed to have caused extinction of all non-avian dinosaurs 66 million years ago.
did crocodiles survive the dinosaur 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.
what is extinction rbt?
Extinction in applied behavior analysis simply refers to the gradual elimination of unappealing and undesirable behaviors. This is accomplished through a series of therapeutic processes that are carried out with care and positivity.
what year will the orangutans be extinct?
According to the IUCN’s Red List of species, the Bornean orangutan’s population fell by more than 60 per cent between 1950 and 2010 and is expected to fall by a further 22 per cent by 2025.
why are animal going extinct?
The main modern causes of extinction are the loss and degradation of habitat (mainly deforestation), over exploitation (hunting, overfishing), invasive species, climate change, and nitrogen pollution.
when did the siberian mammoth species become extinct?
Most populations disappeared between 14,000 and 10,000 years ago. The youngest fossils of the mainland population are from the Kyttyk Peninsula of Siberia and date to 9,650 years ago. A 2021 metagenomics study has found that mammoths survived in mainland Siberia until 3.9 ± 0.2 thousand years ago.
what is being done to prevent polar bear extinction?
The Polar Bear Conservation Management Plan, which focuses on actions for the two US subpopulations in Alaska and was introduced by the US Fish & Wildlife Service (USFWS), stresses the importance of climate change mitigation in curbing the loss of the polar bear’s sea ice habitat.
What is the molar extinction coefficient of concentration?
The term molar extinction coefficient (ε) is a measure of how strongly a chemical species or substance absorbs light at a particular wavelength. It is an intrinsic property of chemical species that is dependent upon their chemical composition and structure.
Did any dinosaurs survive?
Part of the Dinosaurs: Ancient Fossils, New Discoveries exhibition. Not all dinosaurs died out 65 million years ago. Avian dinosaurs–in other words, birds–survived and flourished. Scientists at the American Museum of Natural History estimate that there are more than 18,000 species of birds alive today.
What is being done to protect biodiversity in Madagascar?
We work with local communities and authorities to stem the destruction of forests for charcoal and slash-and-burn cutting for cropland. A long-running education programme promotes sustainable use of the forests, and other initiatives encourage sustainable alternative livelihoods, such as fuel wood plantations.
How many American buffalos are left?
Bison were hunted almost to extinction in the 19th century. Fewer than 100 remained in the wild by the late 1880s.
What is the extinct bird of New Zealand?
What is a Moa? Moa are an extinct group of flightless birds, classed scientifically as ratites and closely related to the extant ostrich, emu, and cassowary, as well as the extinct elephant bird from Madagascar.
Is a species that has died out and no individuals are left?
So, what is extinction? Extinction of a particular animal or plant species occurs when there are no more individuals of that species alive anywhere in the world – the species has died out. This is a natural part of evolution.
What is being done to protect primates in Madagascar?
Other activities include working with local schools, where we distribute educational materials to raise awareness and run teaching sessions. We also facilitate reforestation projects, which encourage local people to engage with protecting the precious rainforest the lemurs inhabit.
How are we protecting polar bears?
We can all contribute to reducing climate change, and therefore help polar bears and other endangered species. A significant cause of climate change is the emission of polluting gases from burning fossil fuels, such as coal and oil. Fossil fuels are burned when we use electricity or drive our cars, among other things.
Why did only birds survive the dinosaur extinction?
Birds are descended from the maniraptoran dinosaurs but they had two important adaptations that helped them survive. First, they had beaks instead of teeth, which allowed them to crack open seeds and nuts buried in the topsoil.
