40 percent of the world’s economy and 80 percent of the poor are derived from biological resources. This means, the richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change.
 
        
             
        
        
        
Multiply 5730 years by 2 since two half-lives have gone by for carbon.
<u>Explanation</u>:
The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years  
The half-life of carbon-14 is 5730 years.  
In this manner, after  
1 half-life there is 50 % = 1/2 of the first amount left.  
2 half-lives there is 25 % = 1/4 of the first amount left.  
25% is two half-lives.  
Every 50% of life requires 5730 years.  
So two half-lives require 2 × 5730
 
        
             
        
        
        
Answer:
For those who eat a well-balanced diet and have no metabolic disorders, excess dietary carbohydrates are converted by the liver into complex chains of glucose called glycogen. Glycogen is stored in liver and muscle cells and is a secondary source of energy to freely circulating blood glucose.
 
        
             
        
        
        
Answer and Explanation:
