The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.
The answer is C- Excretory system. Hope this helps :)
Answer:
antibiotics
Explanation:
pesticides have to do with nature and killing bugs, weeds, etc. Irrigation has to do with watering plants and people. Trucks are vehicles that transport. Antiobiotics help kill bad bacteria in your body when your sick, so that's health related.
Outer hair cells change their axial dimensions in response to electrical stimulation.
What is basilar membrane motion?
Hair cell stereocilia move as a result of the basilar membrane's movement. The tectorial membrane and the hair cells, which are connected to the basilar membrane, move along with it when it moves, and the stereocilia bend in response to the relative motion of the tectorial membrane.
The hair cells that are linked to the auditory nerve fibers are stimulated by the basilar membrane's movement. While the outside hair cells actively affect the basilar membrane's vibrations, the inner hair cells convert hydromechanical vibration into action potentials.
With each sound cycle, the intracellular voltage of the outer hair cells varies, causing them to lengthen and contract. This increases the organ of Corti's vibration, enabling exceptionally high hearing sensitivity and frequency selectivity.
