Answer: Ventilation, diffusion, and perfusion

Explanation:
Answer 2
Answer:

Final answer:

The three key principles based on which gas exchange happens in the respiratory system are: partial pressure difference, large surface area for exchange, and effective transportation of gases.

Explanation:

The respiratory system relies on three main principles for gas exchange:

  1. Partial pressure difference: The exchange of gases (oxygen and carbon dioxide) in the lungs happens according to the differences in partial pressures. Oxygen moves from areas of higher to lower partial pressure, enabling it to enter the bloodstream where its pressure is lower.
  2. Surface area for exchange: The structure of the lung surface, specifically the alveoli, provides a large surface area for effective gas exchange.
  3. Transport of gases: Gases like oxygen and carbon dioxide are carried in the bloodstream. Oxygen is primarily carried attached to hemoglobin in red blood cells, while carbon dioxide is primarily transported in plasma as bicarbonate ions.

i'd say during facilitated diffusion this happens but it's not an option so i'd have to say facilitated transport then, i hope i'm right and i hope this helps!! :)

Few producers live deep below a lake's surface. Suggest an explanation for this pattern

Answers

Answer;

-Since sunlight is where most of the energy in an ecosystem comes from, there is less sunlight deep in a lake meaning less organisms can survive.

Explanation;

-The reason why many plants don't live deep below a lake's surface is because lakes don't normally have chemical vents. Thus, making it hard for producers to find any sources of energy in the dark, deep waters of the lake.

-Since the deepest parts of a lake receive the least light, the ability of submerged macrophytes (plants larger than algae) to establish colonies is limited.

-The combination of low oxygen levels and low light limits the growth of plant communities at great depths; many plants living in very deep water have adaptations such as elongated stems or long structures so that at least some of the plant is in the water nearer the surface where it can photosynthesis.
Producers are living organisms that enables the production of food or is able to produce their own food through the photosynthetic mechanism of their structures which has helped many organisms survive. 

This is because there is not enough sunlight and air which are needed for the producer to make food. 

Which statement about ionic bonds is correct

Answers

Answer:

Explanation: Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion
