Answer to Question 1

The Ediacaran fauna are the first multicelled organisms found in the fossil record. They are important
because they represent a transition faunal assemblage between generally life-poor Proterozoic and the
Paleozoic with its sudden appearance of many life forms. They may be the ancestors of some Early
Paleozoic organisms, or they may represent an early evolutionary development that died out.



Answer to Question 2

Eukaryotic cells have a cell nucleus, more advanced internal structures, and mostly reproduce sexually.
By the Mesoproterozoic, or even as early as 1.4 billion years ago, two or more prokaryotic cells
entered into a symbiotic relationship and eventually could only exist as a whole. The evolution of
eukaryotic cells allowed the evolution of multicelled organisms

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
