This hypothesis states that about 65 million years ago, a giant meteorite crashed into the the earth. The impact of the collision raised enough dust to block the sun's rays for many years. The earth probably became colder, plant life began to die, and many animal species, including dinosaurs, became extinct. As the dust settled over the earth, it formed a layer of iridium-laden rock.
What else can I help you with?
Is this true or false. A scientific inquiry often began with developing a hypothesis?
False
What is an experiment which seems to validate a hypothesis?
An experiment that seems to validate a hypothesis is the classic Pavlov's dogs experiment, where Ivan Pavlov conditioned dogs to salivate in response to a bell. The hypothesis was that dogs could be conditioned to associate a neutral stimulus (the bell) with a significant stimulus (food). After repeated pairings, the dogs began to salivate upon hearing the bell alone, providing strong evidence for the hypothesis of classical conditioning. This experiment demonstrated the principles of associative learning, confirming the hypothesis through observable behavior changes.
Explain why a theory is also a hypothesis example of a theory that is a hypothesis supported by repeated experimentation?
A theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence, whereas a hypothesis is a proposed explanation that can be tested through experimentation. A classic example of a theory that began as a hypothesis is the germ theory of disease, which posited that microorganisms cause many diseases. This theory was supported by repeated experimentation and observations, such as Pasteur's work on fermentation and Koch's postulates, ultimately leading to its acceptance as a foundational principle in microbiology and medicine.
Who was Hans Selye?
Hans Selye, a Canadian scientist (1907-1982), noticed that people who suffered from chronic illness or disease showed some of the same symptoms. Selye related this to stress and he began to test his hypothesis.
Why are hypothesis never accepted by scientist?
Hypotheses are ideas which are, as yet, unsupported by evidence. As a hypothesis becomes backed up by mathematical formulae and observational data, it may, if it is sound, become a theory. All scientific theories began life as hypotheses, it is merely a case of which hypotheses become theories, and which fall down by the wayside after being discredited or having lacked support.
The rebirth of science medicine occurred when?
The rebirth of scientific medicine occurred during the Renaissance, particularly in the 16th and 17th centuries, when scholars began to apply empirical observation and experimentation to the study of human anatomy and disease. Pioneering figures like Andreas Vesalius challenged long-held medical doctrines by conducting dissections and publishing detailed anatomical studies. This period also saw the development of the scientific method, which emphasized observation, hypothesis, and experimentation, ultimately leading to significant advancements in medical knowledge and practices.
Is this true or false. A scientific inquiry often began with developing a hypothesis?
False
What is the four-stage hypothesis for the origin of life?
The four-stage hypothesis proposes that life began with the abiotic synthesis of small organic molecules, followed by the formation of polymers like RNA, then the packaging of these molecules into protocells, and finally the development of self-replicating molecules within these protocells, leading to the first living organisms.
What piece of evidence was suggested by Edwin hubble?
Edwin Hubble suggested the evidence of an expanding universe based on his observation of galaxies moving away from each other with increasing speed. This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.
The idea that the moon's development began when the large object collided with earth is called what?
The idea that the moon formed from debris created by a giant impact between Earth and a Mars-sized object is called the Giant Impact Hypothesis. This theory suggests that material ejected from this collision eventually coalesced to form the moon.
Did the Egyptians began the development of sanitary systems by building sewers and aqueducts?
No the Romans used the knowledge from the Greeks and began the development of sanitary systems.
Who began development of the KDE?
Matthias Ettrich started KDE development in 1996.
Use in the sentence the word observersion?
I can give you several sentences.Careful observation will reveal that the burglar had a key.The scientist began his observation of the strange rock.You powers of observation are amazing.
Who began the Hindu religion?
Nobody. Hinduism is just an observation on how the world and the universe works and how everything is related.
When did sociology become a science?
Sociology began to emerge as a science in the 19th century, particularly with the works of Auguste Comte, Karl Marx, and Emile Durkheim. These early sociologists laid the foundation for the scientific study of society through systematic observation, data collection, and theory development.
How did nationalism affect the development of the US?
The US began to assert power as nationalism grew. *_*
