Answer:
The living organisms must not reach equilibrium in the concentration of oxygen and carbon dioxide so that the Exchange of gases continues . Otherwise respiration and photosynthesis will stop.
Explanation:
- Gases move along the concentration gradient i.e. from their higher concentration to lower concetration.
- If living organisms reach a equilibrium of carbon dioxide and oxygen concentration, then The gases will not move in and out of the cells.
- This is because at state of equilibrium the concentration of gases on both side become equal and the movement completely ceases.
- If gaseous exchange in the body stops the process of respiration and photosynthesis in Plants and respiration in animal will completely stop.
Answer:
The electrical impulse travels from the sinus node to the atrioventricular node (also called AV node). There, impulses are slowed down for a very short period, then continue down the conduction pathway via the bundle of His into the ventricles.
Prokaryotic cells have a simpler structure than eukaryotic cells.
Evidence shows that eukaryotic cells evolved from prokaryotic cells.
Some might argue that prokaryotic cells are less important than
eukaryotic cells. But a case can be made that prokaryotic cells are just
as important to life on Earth today as eukaryotic cells. Which do you
think is true? Are prokaryotic cells important to life on Earth? Analyze
the similarities and differences of these cell types to explain your
position.
why this is in my portfolio
I chose this because I
think I wrote my argument well and because if I put this in my portfolio
more people will know how awesome prokaryotes are

Enzymes
Enzymes have an active site where the substrate meets. This is where and how products are broken down. The break down of substrates through the use of enzymes is referred to as the lock and key model. Hope this helps
