Speed of sound in water = 1500 m/s
frequency = 20Hz
wavelength = s/f = 1500/20 = 75m
Explanation:
Un estimulo es cualquier cambio que es capaz de producir una respuesta por parte del organismo. Los receptores son estructuras muy especializadas capaces de percibir los estímulos y convertirlos en impulsos nerviosos
the answer is A because restriction enzymes function in cutting strand of DNA at specufic sites
Answer:
The material through which a wave travels is called a medium
Explanation:
Answer:
B -the absence of the inducer, but not in its presence
Explanation:
In positive repressible regulalor mechanisms transcription of the structural gene(s) occurs in the absence of the inducer because proteins are normally bound to the pertinent DNA segment. when an inhibitor is bound by the inducer, it is prevented from binding the DNA. which will the stops the activation and transcription of the structural genes.
Example of positive repressible regulator is Activator .
Regulating the rate of transcription is a mechanism of gene regulation leading to the productionn of more than one protein product from a single gene.
