Answer:
I believe there are 6 
Explanation:
Protons are the positively charged circles (blue)
Neutrons are the Neutral  (red)
and the others (green) are called electrons
 
        
                    
             
        
        
        
MRNA is a short lived form of genetic information that is used in transcribing the genetic information, hence it is not very useful for analysis since it is fragile and wrong transcriptions happen quite often. SNPs (Single Nucleotide Polymorphisms) are a form of genetic mutation; they are more frequent than most other mutations since a single transription error may lead to this. While SNPs are important in genetic analysis and getting information about causes of disease, they are not very helpful in determining your maternal lineage. Similarly, while nuclear DNA contains a large portion of our genetic information, half of it is from our fathers and half from our mothers, so the analysis becomes hazy very soon. Mitochondrial DNA instead is directly passed down from mother to her offspring since the embryo contains only the mitochondria of the ovary. Thus, studying differences between mitochondrial DNA, one can gain information about his maternal lineage and go back to Mitochondrial Eve, the person from which all living persons have gotten their mitochondria from. Thus, the correct answer is c.

Answer:
level 2 = 3,000  level 3=300
Explanation:
Only 10 percent will be transferred to the next level and 10 percent of 30,000 is 3,000. 10 percent of 3000 is 300
