In diffusion, molecules travel from a higher concentration to a lower concentration. When you put a drop of ink in a glass of water, the spreading of the ink in the water is called diffusion. Similarly, if you spray an air freshener in one corner of a room, eventually people on the other side of the room will be able to smell it as well because the scent has diffused.
In osmosis, molecules also travel from higher concentration to a lower concentration. However, osmosis specifically refers to the movement of WATER molecules. Both of these types of transport are examples of passive transport, which requires no energy
explain the differences between osmosis,diffusion,active transport and bulk transport and give example of materials exchanged by different methods with a justification in each case?
Nutrients are exchanged between the blood and body cell in the capillaries.
osmosis
Human gas-exchange occurs in the lungs. Once air enters the lungs, diffusion of O2 and CO2 occurs in the alveoli.
Diffusion is the process that occurs when a certain concentrated volume of material moves to a less concentrated state. Facilitated diffusion is different and is done with the help of pumps actively transporting materials across the cell membrane to create the equilibrium on both sides of the membrane. ža specific type of passive transport žthe movement of particles from an area of high concentration to an area of low concentration ždissolved particles that are small or nonpolar can diffuse through the cell membrane ždiffusion is used to reach equilibrium –equilibrium: a condition in which the concentration of a substance is equal throughout a space
Gas exchange in Amoeba basically takes place across the whole body surface by diffusion. With their huge surface area which is relative to the volume, single celled animals can productively get oxygen and also remove carbon dioxide via diffusion across the surface. have i helped u from this answer my name is yash verma

Yes, oxygen is transferred to the blood via aveolae in the lungs.

Cnidaria don't have gills or lungs, but they take in oxygen from surrounding water through diffusion.
diffusion: particles move from a high concentration to a low concentration
Yes, the Neolithic Revolution is believed to have spread through a combination of diffusion (movement of people) and cultural exchange, as well as independent societal developments in different regions. The adoption of agriculture and settled life likely spread gradually as people interacted with neighboring groups, shared knowledge, and exchanged goods and ideas.
