When the EPA determines that a pesticide is harmful to wildlife, they have already tested and reviewed it. The next logical step would be to will ban use of the pesticide.
        
             
        
        
        
Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.
a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere 
b) all organisms are descended from one or a few common ancestors
c) the genetic code readily evolves by natural selection 
d) there's only one possible way to encode information in a macromolecule
Answer:
b) all organisms are descended from one or a few common ancestors
Explanation:
Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species. 
 
        
             
        
        
        
The answer is B.
I think its safe to assume we all have had a cup of ice water. The ice always floats at the surface of the water.
 
        
             
        
        
        
It is Chromosomes
Meaning: Chromosomes is a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes
