Answer:
Compressions and Rarefactions
<em>A vibrating tuning fork is capable of creating such a longitudinal wave. As the tines of the fork vibrate back and forth, they push on neighboring air particles. The forward motion of a tine pushes air molecules horizontally to the right and the backward retraction of the tine creates a low-pressure area allowing the air particles to move back to the left.</em>
Explanation:
These regions are known as compressions and rarefactions respectively. The compressions are regions of high air presure while the rarefactions are regions of low air pressure.
<em>Sound waves can also be shown in a standard x vs y graph, as shown here. This allows us to visualise and work with waves from a mathematical point of view. The resulting curves are known as the "waveform" (i.e. the form of the wave.) The wave shown here represents a constant tone at a set frequency.</em>
using subtraction to determine the volume dispensed
making sure that you read the volume with the liquid inside the pipette at eye level
ensuring that air bubbles are not in the column of liquid inside the pipette
The nurse should teach parents that
the most important influence on the eating habits of early school-aged children
is the example of parents and siblings at mealtimes. While children may be influenced by some few other factors, they are most likely to
be influenced by the example and atmosphere provided by their parents more than
any other thing.

D) Mangrove tree crab. There would be a drop in the predators that feed on them. Crocodile populations would drop due to food shortage, and mangroves might also suffer from the high crab populations, so only D is correct.
