What is an example of diffusion in the human body? Examples of diffusion in living organisms Oxygen and carbon dioxide, dissolved in water, are exchanged bydiffusion in the lungs: oxygen moves down a concentration gradient from the air in the alveoli to the blood. carbon dioxide moves down a...
Indicate the tlow of energy In an ecosystem. ny s t unidirectional? Justify. OR AS energy moves progressively through various trophic levels of food chain it is no longer available to the previous level . Give reasons . View Solution What is facilitated diffusion ? View Solution क्...
In osmosis, the direction of water flow is determined by solute concentration. Water diffuses from ahypotonic(low solute concentration) solution to ahypertonic(high solute concentration) solution. In the example above, water moves from the left side of the semi-permeable membrane, where the sugar ...

3 (a) Different gases diffuse at different speeds.(i) What is meant by the term diffusion?[1(ii) What property of a gas molecule affects the speed at which it diffuses?[1(b)Helium is a gas used to fill balloons. It is present in the air in very small quantities. Diffusion can be...
2.1. Diffusion is the spontaneous kinetic movement by which molecules move from an area of a high concentration to an area of low concentration. Diffusion continues until it reaches equilibrium. Osmosis is similar to Diffusion but it’s the process in which water moves across a semi-permeable me...
What happens when diffusion moves molecules across the plasma membrane? What are the proteins used in active transport? Simple diffusion is defined as the movement of Give examples of osmosis in daily life. How does phosphorylation prevent diffusion? Diffusion of water across a selectively permeable ...
AI-based seizure-detection software moves cEEG into the role of a continuous neuromonitor, where an alarm can alert a provider to assess the patient in real-time. This will not replace clinical expertise, but aid neurophysiologists and epileptologists to prioritize work and coordinate care with...
Osmosis by definition is the process of diffusion in which a fluid moves from an area of less concentration a hypotonic solution, of dissolved particles to a region of higher concentration or hypertonic solution, of dissolved particles across a semi-permeable membrane (a membrane that only allows ...
