How refreshing the air in the air sacs helps to maintain a steep diffusion gradient?

It increases the partial pressure of oxygen, so the concentration is higher than that of the blood. Therefore the partial pressure of CO2 decreases , so Co2's concentration is lower than the bloods.

How is diffusion different from active transport?
active transport is different from diffusion. active transport has to do with the movement of chemical substance through a gradient of concentration. diffusion has to do with requiring the expenditure of energy
What is the function of the cell wall in a root hair cell?
The specialized cells help to facilitate diffusion of substances into the plant (especially mineral ions and water). However the whole root system serves this process through acrive transport of the mineral ions which creates a diffusion gradient.
Which of the following forms of cellular transportation helps human cells maintain their sodium and potassium concentration?
diffusion
How do you calculate gradient?
Gradient= Vertical gain / Horizontal distance Hope this helps ;P
What type of diffusion helps glucose enter the cell?
facilitated diffusion
How does osmosis and diffusion help an amoeba survive?
Difussion takes place in amoeba to transport nutrients to every part of amoeba.
Passive and active transport?
Active Transpot. -Pumps -Endocytosis -Exocytosis Passive Transport - Diffusion -osmosis -Facilitated Diffusion active requires energy passive doesnt. active against concentration gradient, passive along concentration gradient.
What is the relationship between homeostasis and diffusion?
Homeostasis is the ability of a system to keep the internal at a constant state. Diffusion is the movement of particles from areas of high concentration to lower concentration. (in Biology its often particles through a cell membrane) Diffusion is a method that helps keep homeostasis, especially within the human body. hope this helps! =)
Why is cultural diffusion important to the study of geography?
Cultural diffusion is important in geography because it helps explain how cultures interact and spread across regions. It provides insights into how human societies evolve, adapt, and influence each other, shaping the cultural landscape of different places. Understanding cultural diffusion is crucial for geographers to analyze patterns of migration, trade, and communication that shape the diversity and interconnectedness of societies worldwide.
Differentiate osmosis from diffusion?
Diffusion is the net movement of molecules from a region of high concentration to a region of lower concentration. Osmosis is the net movement of water through a partially permeable membrane, from a solution of less negative water potential, to a solution of more negative water potential. Both Diffusion and osmosis occur down the concentration gradient. Basically they are the same thing, but osmosis is the diffusion of water in solution, rather then gaseous diffusion. We use the term osmosis to differentiate between gaseous transport and water movement. hope it helps..
Difference between osmosis and diffusion?
Diffusion is the movement of substance (anything- solid ,liquid, gas, etc.) from a higher concentration gradient to a lower concentration gradient.Osmosis is the net movement of water molecules from higher concentration gradient to a lower concentration gradient through a partially permeable membraneSo the difference is that diffusion involves movement of any particles/ substance (e.g. solid, liquid, gas) while osmosis can only occur with water.Another one is that diffusion can occur with or without a membrane but osmosis can only occur with a membrane.Hope this helps. :)
How does physical activity help your education?
It helps you by refreshing your mind and it helps you take your mind off education for a while
