The Eustachian tube is the
structure that allows upper respiratory infections to spread. The eustachian tube is a canal
that links the middle ear to the nasopharynx, which is composed of the upper
throat and the back of the nasal cavity. It also controls the pressure inside
the middle ear, making it equal with the air pressure outside the body.
Answer:
Cardiac Temponade
Explanation:
Cardiac temponade is the condition where the fluid fills the pericardial space and it reduces the filling of ventricles causing issues with contraction and destabilize the blood flow. The condition can get very serious and can cause shock and even death.
Answer:
Refer to bolded below
Explanation:
Photosynthesis involves carbon dioxide and water as the reactants, combining to form glucose and oxygen ( the products ).
Now there is dark photosynthesis and light photosynthesis, where light photosynthesis takes place first considering it converts carbon dioxide (CO2) and water (H2O) into carbohydrates. The ATP energy from the light photosynthesis helps the dark photosynthesis produce the sugars.

Cellular Respiration is simply the opposite. Taking the reactants and products into account, you could simply switch the two and the reactants of photosynthesis = products of cellular respiration, and vice versa. However, ATP energy is made in both. In fact Photosynthesis actually uses some ATP energy in it's chemical reaction...
Thus, we can conclude that Photosynthesis is quite the opposite of Cellular Respiration ( in terms of their chemical formula )
I believe the answers are removing substances in an ecosystem and the usage of organisms to add important materials. Bioremediation naturally happens where small organisms would clean up soil and groundwater that is contaminated. While the latter, is a process where you add organisms to hasten the degradation.
