A) heat is related to speed/ energy of molecules so when it is decreased the molecules slow down and stop bouncing around/ loose energy
Biogechemical cycles depend mostly on bacteria and fungi for decomposition and the recycling of elements.
Natural selection helps the anteater get food easier than others.
Pollen tube growth is one of the most fascinating—and essential—phenomena in the life cycle of flowering plants. After a compatible interaction between pollen grains and the stigma surface, the pollen germinates and forms the pollen tube, which grows through the stigma, style, and transmitting tract to deliver the sperm cells to the ovule."
2) Although pollens of many species germinate in simple aqueous media, stigmas do not provide satisfactory sites for the germination of most foreign pollen... Stigmas not only provide the proper conditions for the germination of pollen from their particular species, they actively inhibit the germination of pollen of many unrelated species.
