Answer:
if you are not using alcohol (95% ethanol), you are not decolorizing the wall of the gram-negative bacteria, which should get rid of the violet color, therefore the safranin stain, in the next step, won't be absorbed in the wall, and the bacteria will end up being purple due to the previous crystal violet stain of the gram-positive bacteria
Explanation:
Answer:
The correct statements are statement 3 and 4.
Explanation:
An alignment of three nucleotides within the RNA or DNA that assists in coding a specific amino acid or instructs the cell to either cease or begin the synthesis of protein is termed as a codon. A sum of 64 probable codons are found that comprise three of the four possible nucleotides, however, only 20 amino acids are present in the majority of the biological species.
The given third statement is true as there are some of the codons known as stop codons that plays an essential role in terminating the process of protein synthesis.
The given fourth statement is also true as codons known as stop codons are not identified by tRNAs, they are identified by ribosomes.
Answer;
180 years.
Explanation;
The average growth rate of mt. Everest is 4 millimeters per year.
Therefore;
For the mountain to grow by 720 millimeters ;
720 millimeter /4 millimeter per year
= 180 years
Therefore; it will take 180 years for mount Everest to grow for 720 Millimeters.
