Parenchyma is the answer because whereas the other two, xylem and phloem are vascular tissues, parenchyma is a packing tissue.
A wave with a height of 5 feet and a wavelength of 15 feet has a wave base of <u>7.5 feet</u>.
A. 7.5 feet
<u>Explanation:</u>
Wave base defines the depth of the water when it is in still condition.
Wave base is half of wavelength.
Wave base = wavelength/2
Given,
Wavelength = 15 feet
So, wave base = 15 feet/2 = 7.5 feet
When the wave height is divided by wavelength then it gives the steepness of the wave.
Therefore, the wave base is 7.5feet.
