Pathogen 3 will most likely be a virus with the features seen in the table.
<h3>
What is a Pathogen?</h3>
This is defined as disease causing microorganism and examples include bacteria, virus etc.
Virus doesn't replicate on its own but only when in the living cells of other organisms and has a protein capsid but lacks nucleus.

Answer:
Air moves into the lungs from atmosphere
Explanation:
As per the gas law, pressure of a gas is indirectly proportional to the volume of the gas. Thus, if volume increases pressure decreases.
Here, the volume of alveoli has increased due to which the pressure within the alveolar space reduces such that the atmospheric pressure outside alveoli becomes higher than the alveolar pressure within the alveoli. Due to this difference in pressure, the air gushes into the lungs.
I would say the respiratory system (the lungs) fail. The lungs are to receive oxygen and it sends it to the heart.
I am not much of a biology nerd but I am taking an educational guess.
All I can say that the lungs need oxygen. Without oxygen, the heart will stop pumping blood and you will be suffocating with this essential. That is why you should never smoke and actually take great care of your precious body.
Carbon skeletons may vary in length, shape, number and location of double bonds and other elements covalently bonded to available sites.
A carbon atom contains four valence electrons thus, exhibiting a strong tendency to make covalent bonds with other atoms so as to complete its octet. Covalent bonds join carbon atoms together in long chains that create the skeletal framework for organic molecules.
A carbon atom could be linked to as many as four additional carbon atoms in an organic compound. Carbon atoms can also quickly form double bonds (where four electrons are shared among two atoms) and triple bonds (where six electrons are shared).
This variation in carbon skeletons contributes to the diversity and complexity of organic molecules.
