When an object such a a stone is dropped into water, it disturbs the surface of the water. waves form at the surface of the water and travel outward from the point of the disturbance.

the diagram below is based on a single frame from a video of the waves that formed when a stone was dropped into water.

if a student were to measure the distance labeled as "z," she would know the value of the of the wave.
a.
wavelength
b.
amplitude
c.
radius
d.
frequency

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
