<span>The invention of the wheel gave the Sumerians the ability to be mobile. By having a mode of transportation other than on foot, the Sumerians could widen their travel abilities and undertake activities not including food-gathering. By being more mobile, trade also increased, which increased the sphere of the culture's influence.</span>
Given :
The half life of Carbon-14 , 
.
Trace amounts of Carbon-14 1/2408 remains.
To Find :
How old is the rock .
Solution :
Let , initial concentration of Carbon-14 is C .
Quantity remains , 
.
Rate constant is :
By first order equation :
![kt=-ln(\dfrac{[A_t]}{[A_o]})\\\\t=-\dfrac{ln(\dfrac{[A_t]}{[A_o]})}{k}\\\\t=-\dfrac{ln(\dfrac{[A_o]}{[A_o]\times 2408})}{1.2\times 10^{-4}}\ years\\\\t=-\dfrac{ln(\dfrac{1}{2408})}{1.2\times 10^{-4}}\ years\\\\t=64887.9\ years](https://tex.z-dn.net/?f=kt%3D-ln%28%5Cdfrac%7B%5BA_t%5D%7D%7B%5BA_o%5D%7D%29%5C%5C%5C%5Ct%3D-%5Cdfrac%7Bln%28%5Cdfrac%7B%5BA_t%5D%7D%7B%5BA_o%5D%7D%29%7D%7Bk%7D%5C%5C%5C%5Ct%3D-%5Cdfrac%7Bln%28%5Cdfrac%7B%5BA_o%5D%7D%7B%5BA_o%5D%5Ctimes%202408%7D%29%7D%7B1.2%5Ctimes%2010%5E%7B-4%7D%7D%5C%20years%5C%5C%5C%5Ct%3D-%5Cdfrac%7Bln%28%5Cdfrac%7B1%7D%7B2408%7D%29%7D%7B1.2%5Ctimes%2010%5E%7B-4%7D%7D%5C%20years%5C%5C%5C%5Ct%3D64887.9%5C%20years)
Therefore , the rock is 64887.9 years old .
Hence , this is the required solution .
As humans migrated throughout the world, populations encountered distinct pathogens, and natural selection increased the prevalence of alleles that are advantageous in the new ecosystems in both host and pathogens. This ancient history now influences human infectious disease susceptibility and microbiome homeostasis, and contributes to common diseases that show geographical disparities, such as autoimmune and metabolic disorders.
Answer:
- complex info; detailed instructions
genetic codes contain complex information; detailed instructions
Explanation:
The genetic code is a set of rules by which information encoded in the genetic material (DNA or RNA sequences) is translated into proteins (amino acid sequences) by living cells.
-The genetic code consists of 64 triplets of nucleotides. these triplets are called codons. With three exceptions, each codon and codes for one of the 20 amino acids used in the synthesis of proteins. that produces some redundancy in the code: MuscleTech amino acids being encoded by more than one codon.
