Scientists long believed that the discovery of a mummy in the Alps, known as Ötzi the Iceman, provided information on how humans lived 5,300 years ago. More recently, scientists used DNA analysis to discover that Ötzi and modern-day humans have DNA markers in common. How did the study of Ötzi's DNA change the way scientists viewed the development of modern humans?

They learned that the DNA found in early humans can be found in today's humans.

Explanation:

Given that DNA analysis demonstrated that Ötzi the Iceman (the mummy in the Alps found between Italian and Austrain border) is virtually like a modern human, even though, he lived in the long past at more than 5,000 years ago.

He exhibits similar physical characteristics to modern man, except that he is shorter in height compared to modern man.

Hence, it can be concluded that the study of Ötzi's DNA change the way scientists viewed the development of modern humans in way that " the DNA found in early humans can be found in today's humans."

a is true because it know the force.

ps maybe give us more info?

answer

explanation

the given equation is

we can rewrite this as:

let

then the equation becomes:

the factors of 8 that sum up to -9 are {-1,-8}

we split the middle term with these factors to obtain,

we factor by grouping to obtain:

apply the zero product property to get:
