The presence of cones in the tree signals its readiness for reproduction, as the cone contains the seeds!
A signal to reabsorb more water and salt. Have a good day =D
Light from distant galaxies can help us calculate how old the galaxies are. By analyzing how the how the light has changed by the time it reached us, we can find out how old the star system from which it originates is.
Evaporation and condensation play major roles in the Earth's water cycle and how it functions. When water evaporates from the ocean due to the sun's energy, it rises in the air and condenses as clouds. Wind carries these clouds over land and eventually these cloud condense more by starting to rain. Once the rain falls, it runs off, and some/most of it returns back to the ocean, where the cycle repeats again. Hope this helps!
