Answer:

Independent - Water/Type of water (salt and pure)

Dependent - Height of plant

Controlled - Amount of water

Explanation:

Independent is what the experimenter manipulates (in this case being the type of water.)

Dependent is what the experimenter measures and is a result of the independent (in this case being the height of plant)

Controlled is what you are trying to keep the same (in this case the amount of water you give each plant.)

Hydrolysis of which molecule is important for translation initiation, elongation, and termination?
abruzzese [7]

Answer:

D. GTP

Explanation:

Initiation of protein synthesis includes binding of mRNA to small ribosome subunit and initiation aminoacyl tRNA. The pairing of the anticodon of the initiating aminoacyl tRNA and initiation codon of mRNA requires GTP hydrolysis and marks the beginning of protein synthesis.  

Elongation stage of protein synthesis requires movement of the ribosome along the mRNA which in turn is facilitated by GTP hydrolysis. As the ribosome moves along the mRNA, the codon of mRNA bind to the respective anticodon of aminoacyl tRNA by using the energy of GTP hydrolysis. The GTPase activity of elongation factor Ef-Tu ensures the fidelity of the process.  

The release factors that recognize the stop codon and serve to mark the termination of protein synthesis use the energy of GTP hydrolysis during the process.
