Chapter 23, Problem 6RQ
Summary Introduction
To describe: The chemical and physical environment in which the first living cells may have evolved.
Introduction: Our Earth was formed before 4.6 billion years from the sun with continuous bombardment of huge rocks and ices. When Earth was formed, chemical evolution began which formed organic molecules. Organic molecules led to evolution of first cells and thus, life evolved.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place.
