This is evidenced by Doppler shift effect. This is the phenomenon where waves that are coming from an object that is accelerating towards your direction are heard at a higher frequency than that of objects moving away from you. This is the same for light (which also has wave-like properties). When observing distant galaxies, astronomers discovered that they all showed to be redshift (change in the frequency of light towards red color). This means that all galaxies are moving away from each other because the universe is expanding.

Answer:

The correct answer is - transformation.

Explanation:

Griffith's experiment was performed by Fredrick Griffith with Streptococcus pneumoniae. Streptococcus P. are rough non encapsulated streptococci that are converted into smooth encapsulated streptococci bacteria in presence of heat-killed smooth encapsulated bacteria.

This experiment was the first experiment that showed that this bacteria can get DNA by the process of transformation.

He suggested that the nonencapsulated bacteria had been transformed into the encapsulated smooth bacteria strain by the transformation process that was somehow part of the dead encapsulated strain bacteria.

Thus, the correct answer - transformation.

Outer hair cells near the center of the basilar membrane will
Likurg_2 [28]

The answer is outer hair cells can be seen near the center of the basilar membrane where the hightest vibration takes place.  The basilar membrane can be seen under the inner hair cells, the movement of stereocilia and the resulting modulation of their ionic currents is likely to be greater for outer hair cells than for inner hair cells.
