Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
<span>The correct answer is that when determining earth's history, scientists use radioactive isotopes to determine the absolute age of fossils and rocks and things like that. They see how things have decayed and changed over time and use these radioactive methods to determine things that happened before time measuring was invented.</span>

The cystic fibrosis is a condition, in which the secretion of mucus in some vital organs such as lungs, pancreas, and stomach becomes sticky and thick.
This condition is caused by the inheritance of the recessive gene responsible for the development of the cystic fibrosis.
The thick and the sticky mucus gets lined up on the walls of the organ and causes the clogging of the tubes and the ducts, hence, instead of providing lubrication they act as clogging agent and causing major damage to some vital organs, especially, lungs and the pancreas.
