Which statement best explains the difference between a law and a theory?
Answer:A law summarizes a series of related observations; a theory gives the underlying reasons for them. Explanation: What is a definition of a theory? A proposed explanation for observations that has been made accompanied with the laws which is accomplish through a series of tested hypothesis over time .
Which statement best explains the difference between a law and a theory quizlet?
Terms in this set (62) Which statement best explains the difference between the law and the theory? A) A law is truth; a theory is mere speculation.
Which statement best explains the difference between a scientific law and a scientific theory?
A scientific law is a statement based on repeated observation. It will always be true under a certain set of circumstances. A scientific theory is well supported (by evidence) explanation for an occurrence in the natural world.
How are theories different than laws?
In simplest terms, a law predicts what happens while a theory proposes why. A theory will never grow up into a law, though the development of one often triggers progress on the other.
What do theories and laws have in common?
Answer and Explanation: One major factor that a scientific hypothesis, theory, and law have in common is that they are all based on observations.
Can theories be proven?
Both scientific laws and theories are considered scientific fact. However, theories and laws can be disproven when new evidence emerges.
What is the most accepted theory?
the Big Bang theory
What is a theory that is proven called?
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not “guesses” but reliable accounts of the real world.
Is evolution theory or fact?
Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change.”
Why are there still monkeys if we evolved from them?
Firstly, humans did not evolve from monkeys. Instead, monkeys and humans share a common ancestor from which both evolved around 25 million years ago. This evolutionary relationship is supported both by the fossil record and DNA analysis. A 2007 study showed that humans and rhesus monkeys share about 93% of their DNA.
Who invented human?
Despite the 1891 discovery by Eugène Dubois of what is now called Homo erectus at Trinil, Java, it was only in the 1920s when such fossils were discovered in Africa, that intermediate species began to accumulate.
When did man appear on Earth?
seven million years ago
What color was Neanderthal skin?
2007). MC1R is a receptor gene that controls the production of melanin, the protein responsible for pigmentation of the hair and skin. Neanderthals had a mutation in this receptor gene which changed an amino acid, making the resulting protein less efficient and likely creating a phenotype of red hair and pale skin.
What did a Neanderthal woman look like?
She was an early modern human, clad in an animal-skin coat with a wolf-fur trim. She had long legs, and her hair was worn in braids. He cleared his throat, looked her up and down, and – in an absurdly high-pitched, nasal voice – deployed his best chat-up line.
What Colour hair did Neanderthals have?
red hair
What did we inherit from Neanderthals?
DNA Inherited From Neanderthals May Increase Risk of Covid-19. The stretch of six genes seems to increase the risk of severe illness from the coronavirus. A stretch of DNA linked to Covid-19 was passed down from Neanderthals 60,000 years ago, according to a new study.
Is straight hair Neanderthal?
Neanderthal ancestors also passed along some traits for sleeping patterns, mood, and skin tone and hair color, research shows. Pobiner said she inherited a Neanderthal gene associated with straight hair, although she says her hair is not, in fact, stick-straight.
What is the evidence for humans and Neanderthals interbreeding?
However, in 2016 researchers published a new set of Neanderthal DNA sequences from Altai Cave in Siberia, as well as from Spain and Croatia, that show evidence of human-Neanderthal interbreeding as far back as 100,000 years ago — farther back than many previous estimates of humans’ migration out of Africa (Kuhlwilm et …
Did Neanderthals mix with humans?
In Eurasia, interbreeding between Neanderthals and Denisovans with modern humans took place several times. The introgression events into modern humans are estimated to have happened about 47,000–65,000 years ago with Neanderthals and about 44,000–54,000 years ago with Denisovans.
Which race has most Neanderthal DNA?
East Asian
What does a denisovan look like?
Cell, September 2019. Using DNA analysis, scientists have determined how Denisovans differed physically from modern humans and Neanderthals. Denisovans resembled Neanderthals in many key traits, such as robust jaws, low craniums, low foreheads, wide pelvises, wide fingertips, and large rib cages.
