The diffusion is the transfer of the molecules from one place to another in the direction of the particle gradient. In the process of diffusion, the net movement of the molecules to place of lower molecule concentration.
The osmosis can be defined as the flow of the water molecules along a concentration gradient. the plasmolysis causes the movement of the water molecule from the plant cell due to the contraction of the protoplast. The active transport takes place when the molecules move from a region of lower to higher concentration. Hence, a, c, and d options are incorrect.
The most important part of the cycle is bacteria. Bacteria help the nitrogen change between states so it can be used. When nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by plants. Animals then get their nitrogen from the plants.
When a cyclic AMP is dissolved in water it loses its bond between its P atom and its main aromatic ring. In the pictures attached, is shown in red the bond that's lost. The cyclic AMP is a messenger involved in many biological processes.
Along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.
A number of human activities can impact on the water cycle: damming rivers for hydroelectricity, using water for farming, deforestation and the burning of fossil fuels
