A) a common ancestor
Homologous structures are structures that are similar in related organisms. There is a basic pattern of bones which can be inherited from a common ancestor
Answer:
Hello. You did not enter the answer options, but the factor that most directly influences a measurable result in an experiment is the manipulation of the variables.
Explanation:
In an experiment, the manipulation of variables becomes highly important so that it is possible to measure, that is, evaluate the result. This is because it is the variables that express values that represent the characteristics that are being analyzed and studied within the experiment. Therefore, the manipulation between them must be done in a very rational and balanced way so as not to modify the values shown by them, changing the data and generating false or immeasurable data.

Explanation:
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.
The study of the chemical reactions that take place in all living organisms is called Biochemistry
