Explain how are precipitation and temperature between the polar and the tropical climate zones?

There are regions with tropical climate that have large temperature variations between summer and winter and these variations could be as high as 25-30 degree Celsius. Polar climate zone is characterized by extremely low temperatures throughout the year.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
