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.
False
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.
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 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.
False
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.
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 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.
No the Romans used the knowledge from the Greeks and began the development of sanitary systems.
Matthias Ettrich started KDE development in 1996.
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.
Nobody. Hinduism is just an observation on how the world and the universe works and how everything is related.

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.
