Answer:
The correct answer is "I would suggest her to change the Gram positive control from Bacillus subtilis to other bacteria".
Explanation:
Bacillus subtilis, and the species from the genre Bacillus, are known for losing the crystal violet coloration during Gram testing. It is likely that B. subtilis might look pink under the procedure for this reason. I would suggest to change her Gram positive control from B. subtilis to other bacteria. For instance, she could try with Staphylococcus aureus, a widely used bacteria as Gram positive control.
 
        
             
        
        
        
Answer:
The most likely explanation for the truncated polypeptide -due to the substitution of cytosine for adenine- is that mutation introduced a stop codon in the middle of the gene.
Explanation:
A codon consists of three nucleotides -in the RNA chain- whose order determines a specific amino acid. Not all codons code for amino acids, as there are termination codons, also called stop codons, which are UAG, UGA and UAA.
If in Manny's computer model, the substitution of cytosine by adenine produced a termination codon, the synthesis of a peptide is stopped prematurely resulting in a truncated peptide.

Water moves from the soil to the leaves of mesophytes by osmosis and xylem conduction.
<h3>What are mesophytes?</h3>
Mesophytes are plants that are adapted to moderate water environments only. In other words, they cannot survive extremely or extremely wet environments. 
Water moves from the soil to the leaves of mesophytes as follows:
1. Water moves into the root hair by osmosis
2. Water is conducted upward from the root hairs by special cells known as xylems.
3. Conducted water reaches various plant parts, including leaves.
