Answer:The water cycle is often taught as a simple circular cycle of evaporation, condensation, and precipitation. Although this can be a useful model, the reality is much more complicated. The paths and influences of water through Earth’s ecosystems are extremely complex and not completely understood.
I hope this helps and have a brainly good day :D
1. Polymer refers to a lengthened, chain-like molecule comprising repeated units associated end to end.
2. Ceramic refers to a hard, brittle, corrosion and heat tolerant substance formed by administering a non-metallic mixture of minerals to intense heat.
3. Thermoset refers to the plastics, which exhibit low elongations and cannot get recycled again.
4. Thermoplastic refers to the plastics, which exhibit high elongations and can be recycled.
5. Crystal refers to the solid form originating from the organization of ions, atoms, or molecules in precise patterns of geometry.
6. Composite refers to a carbon fiber entrenched in a polymer resin matrix.
Answer:
Active transport occur in the uphill direction where passive transport occur in the downhill direction this is the principle comparison between passive transport and active transport.
Explanation:
Passive transport involves simple transport mechanism such as diffusion,osmosis and facilitated diffusion that help in the transport of molecule across the membrane from high concentration region to the region of low concentration untill equilibrium is reached. No additional energy is required to carry out passive transport. oxygen, carbon dioxide,water, glucose molecule are transported by passive transport mechanism.
Active Transport involves various ion channels which helps in the movement of molecules from low concentration region to the high concentration region .Additional energy in form of ATP is required to stimulate the active transport. Various ions such as Na+,K+, Ca2+, amino acids are transported by active transport.
