What is true about microevolution?
iris [78.8K]
Microevolution refers to changes that occur within a single species or group or organisms.  Microevolution, as opposed to macroevolution, occurs in a short period of time. In microevolution, the ancestor and the descendant obviously belong to the same type.  For example, certain pests have evolved in such a way that they become immune to pesticides; the same thing has happened to certain weeds and herbicides. Hope this helps.

The D string on a violin has a frequency of 293 Hz when it is in tune. Ca<br> lculate the period
masya89 [10]

The period of the D string on the violin would be 0.0034 seconds.

<h3>What is the period of a wave?</h3>

The period of a generated wave is the time it takes for the wave's wavelength or successive crests or troughs to pass through a specific point. In other words, it is the time required to complete a full cycle of oscillation.

Mathematically, the period of a wave is given by:

Period = 1/f

where f is the frequency of the wave.

In the case of the D string of the violin in the illustrated problem, the frequency of the wave is given as 293 Hz when it is in tune. Thus, the period can be calculated as:

Period  = 1/293

            =  0.0034 seconds

Thus, the period of oscillation of wave generated by the D string on the violin with a frequency of 293 Hz is 0.0034 seconds.
