The pulmonary structures refers to the organs of the body that are involved in the breathing process. These include the nostril, the oral cavity, the trachea, the two lungs, etc. Humans take oxygen from the environment to facilitate the respiratory process, at the same time they release carbon dioxide to the environment using the pulmonary structures.
It represents a sodium ion, this may not answer it as there are no options given.
Earthquakes occur most frequently near active margins.
The three major zones of the ocean floor are;
continental margin,<span> </span>deep-ocean basins<span>, and </span>mid-ocean ridges
Continental margins has two types of margins, active and passive margins, these both margins are located near coastlines.
As the mass of the object is increased, the force applied to the object increases to maintain the acceleration of the object.
<h3>
Acceleration of the objects</h3>
The acceleration of the objects is determined from Newton's second law of motion as follows;
F = ma
a = F/m
<h3>for mass of 5 kg and force of 2 N</h3>
a = 2/5 = 0.4 m/s²
<h3>for mass of 7 kg and force of 4 N</h3>
a = 4/7 = 0.57 m/s²
<h3>for mass of 10 kg and force of 6 N</h3>
a = 6/10 = 0.6 m/s²
Thus, from the data above we can conclude that, as the mass of the object is increased, the force applied to the object increases to maintain the acceleration of the object.
