Answer:
The correct answer is 327.78. 
Explanation:
A mortality rate refers to the determination of the rate of the occurrences of deaths in a given population in the course of a particular time period. The formula for finding the mortality rate is:  
Deaths taking place in a given time duration / the size of the populace among which the deaths have taken place × 10ⁿ
The given population of the country is 250 million
The number of individuals died due to a certain disease is 819450
Thus, the mortality rate per 100000 can be calculated as:  
819450 / 250000000 × 100000 = 327.78 deaths per 100,000 people.  
 
        
             
        
        
        
I temperature will continually rise until it melts assuming you do not stop applying heat to the ice. It doesn’t really matter at what temp below freezing you start as long as you go above freezing the ice will melt.
        
             
        
        
        
The correct answer is: Promoter
Promoter is a sequence on DNA molecule that initiates transcription of a particular gene (RNA polymerase binds to a promoter).
mRNA is a product of transcription from DNA and it has  
5′ untranslated region- after the start codon, usually responsible for regulation of translation
Protein-coding region- composed of codons that caries the information for protein synthesis (translation).  
Start (the first codon, usually AUG triplet) and stop codons (the last codon for the termination of translation)
 3′ untranslated region-after the stop codon, usually responsible for mRNA stability and localization.
