A. Intracellular
The pathway water takes to reach the xylem cells in which it passes through each cell of the cortex is the intracellular route.
        
             
        
        
        
The question is incomplete as it does not have the options which are:
(a)DNA (b)tRNA (c)rRNA (d)mRNA
Answer:
Option-mRNA
Explanation:
The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.
The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.
This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.
Thus, mRNA is correct.
 
        
             
        
        
        
Offspring   with  a  3:1  ratio  suggest  that  both  parent  that   both  parent  that   give  rise   to  this  offspring  were  both   heterozygous.  Heterozygous  individual   is   someone  who  has  two  different  allele  at  a  locus whereby  by  one  gene  is   dominant   over  the  other  gene.  example  of  heterozygous   parent   is  a parent  Aa   pair  of  alleles.  In  this  pair  gene  A  is  dominant  over  gene  a
        
                    
             
        
        
        
Because it's vital to the survival of all species, not just human, that we have resources such as food and water. Also that those resources be clean and healthy. We also need to manage resources such as oil to make sure there are fewer wars like the ones happening in the Middle East. If you need anything else just message me.
