Answer: Importance of replication in experiments
Explanation: Getting the same result when an experiment is repeated is called replication. ... Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
Answer:
Movement of the tympanic membrane causes displacement of the malleus.
Movement of the malleus causes movement of the incus and stapes.
Movement of the oval window establishes pressure waves in the perilymph of the vestibular duct
The pressure wave distorts the basilar membrane on its way to the round window
Distortion of the basilar membrane forces the hair cells of the organ of Corti toward or away from the tectorial membrane
Displacement of the stereocilia stimulates sensory neurons of the cochlear nerve.
The different frequency sound waves are relay as action potential to the auditory center of the brain.The brain analysis these, based on the frequencies received.This may Interpreted as high pitch, or low pitch sounds.
Explanation:
Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.
<u>EXPLANATION: </u>
- Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body.
- But the polysaccharide like cellulose cannot be absorbed by our body.
- Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity.
- Also, molecules of each micro-fibril are so tightly packed structure and prevent the penetration of enzymes.
- Thus, cellulose degradation requires a complex enzyme and cellulose.
