The answer is B because convection is the transfer of heat without two objects touching.
        
                    
             
        
        
        
Explanation:
Low power objective shows more field of view but does not give appreciable details about the view. 
- In the root tip of onions, the cell walls are distinctly visible and they are arranged in a rectangular mosaic pattern. 
- The nucleus stands out appreciably and it is tiny. 
- The cytoplasm is also visible. 
- Root cells do not have chloroplast since they do not take part in photosynthesis.

Answer:
this mutation may change the open reading frame of the resulting RNA sequence and its final product, which is a protein in the case that this gene is used to synthesize a messenger RNA (mRNA) sequence
Explanation:
During the transcription, a region of DNA named 'gene' is used as template to produce an RNA molecule, typically a primary transcript of mRNA (pre-mRNA). Subsequently, this pre-mRNA suffers a process named RNA processing in order to generate a mature mRNA which is finally used to create a protein by a process called translation. If a deletion occurs during transcription, it may change the open reading frame (ORF) of the resulting mRNA when the mutation occurs in an exon of the protein-coding gene (i.e., occurs a frameshift mutation), while this deletion may not have any effect if it is localized within the introns which are removed during RNA processing. A frameshift mutation will change the amino acids that are added to the nascent polypeptide chain during translation.
 
        
             
        
        
        
It would give nature a place to fight back, and become more healthy, and less hindered. Cities mess up the evaporation cycle, and because of parks, the water is able to be soaked up by grass, and then released through evaporation. When it rains over a city, the water goes into gutters, and becomes more polluted.
