Why did plesiosaurs go extinct and what factors contributed to their disappearance from the Earth?
Plesiosaurs went extinct around 66 million years ago due to a combination of factors, including environmental changes, competition with other marine reptiles, and possibly the impact of a large asteroid that caused widespread destruction. These factors led to a decline in their population and ultimately their disappearance from the Earth.

Why did the plesiosaurs go extinct and what factors contributed to their disappearance from the Earth?
Plesiosaurs went extinct around 66 million years ago, likely due to a combination of factors. The main reason for their extinction is believed to be the mass extinction event that wiped out the dinosaurs, known as the Cretaceous-Paleogene extinction event. This event was likely caused by a massive asteroid impact, volcanic activity, and climate change. These factors led to drastic changes in the environment, including a decrease in food sources and habitat loss, which ultimately contributed to the extinction of the plesiosaurs.

What is an extinct organism?
An extinct organism is a species that no longer exists because all members of that species have died out or evolved into something else. Extinction can happen due to natural factors like environmental changes or competition, or because of human activities like habitat destruction or hunting. Fossils are often the only evidence that extinct organisms ever lived.
The development of humans was directly dependent on?
The development of humans was directly dependent on factors such as evolution, adaptation to changing environments, use of tools, development of social structures, and increased brain size and cognitive abilities. These factors contributed to our survival and success as a species.
What were two factors responsible for Mendel success?
Two factors that contributed to Mendel's success were his careful experimental design and his meticulous record keeping. These allowed him to accurately document patterns of inheritance in pea plants and derive his groundbreaking laws of genetics.

What are the theories about the disappearance of the neanderthals?
Some theories suggest that Neanderthals interbred with anatomically modern humans, leading to their disappearance through genetic assimilation. Others propose that environmental factors, competition for resources, or even direct conflict with modern humans contributed to their extinction. It is likely that a combination of these factors, rather than a single cause, led to the disappearance of Neanderthals.
Where the neanderthals disapear?
It is believed that Neanderthals went extinct about 40,000 years ago, possibly due to a combination of factors such as competition with modern humans, climate change, and limited adaptability. Interbreeding with early humans also contributed to their disappearance, as traces of Neanderthal DNA can still be found in some human populations today.
What explanations have scholars given for the disappearance of the Minoans?
Scholars have proposed several explanations for the disappearance of the Minoans, including natural disasters such as volcanic eruptions and earthquakes that might have devastated their cities and agricultural systems. Some theories suggest that invasions by Mycenaean Greeks contributed to their decline, while others point to internal factors like social upheaval or economic decline. Additionally, climate change could have affected their agricultural productivity, leading to vulnerability and eventual collapse. The combination of these factors likely contributed to the gradual decline of Minoan civilization.
All what contributed to the failure of the English settlement at Roanoke EXCEPT?
The factors that contributed to the failure of the English settlement at Roanoke included lack of adequate supplies, conflicts with Native Americans, and the mysterious disappearance of the colonists.

How did the hohokum tribe disappear?
The disappearance of the Hohokam tribe is attributed to a combination of factors, including prolonged drought, environmental degradation from agricultural practices, conflicts with other tribes, and possibly infectious diseases introduced by Europeans. These factors are believed to have contributed to the decline and eventual abandonment of Hohokam settlements around the 15th century.

Why did the settlers traveling to Roanoke have a difficult time when there?
The settlers traveling to Roanoke faced difficulties due to harsh weather conditions, lack of resources, conflicts with Native American tribes, and communication challenges. These factors contributed to the failure of the settlement and the mysterious disappearance of the colonists.
Why was the Roanoke settlement doomed from its inception?
The Roanoke settlement faced challenges from the beginning due to issues such as limited resources, conflicts with Native Americans, and lack of support from England. These factors, combined with harsh conditions and internal disputes, contributed to the eventual disappearance of the colonists.
What is the disappearance of a species from all part of an environment?
The disappearance of a species from all parts of an environment is known as extinction. This occurs when the last existing member of a species dies, leading to its complete disappearance from the planet. Extinction can be caused by various factors, including habitat destruction, climate change, pollution, and hunting.
What can kill a dinosaur?
Dinosaurs became extinct around 65 million years ago due to a combination of factors, primarily believed to be a large asteroid impact and volcanic activity. Other factors such as climate change and disease may have also contributed to their extinction.
