Answer:
8. T= d/s = 139/13 = 11.1 seconds (rounded to 1dp)
9. d= sxt = 3 x 15 = 45m
10. d= sxt = 2.5 x 5 = 12.5m
Explanation:
Answer:
The plant hormone ABA or abscisic acid is help in regulating the guard cells via its effect on osmotically changes in turgor. ABA inhibits the proton ATPase, slow down the anion channel and other influences that result in depolarization of membrane potential guard cells that leads to efflux of the K+ closure of stomatal.
Plants have feedback mechanisms that have evolved as well. In stress conditions such as drought these mechanisms involve in closing the guard cells in order to water loss through transpiration.
When continents broke apart from Pangaea lots of different species got separated to different parts of the world. The animals and other living things had to have learned how to adapt to the different climates or they would die and go extinct.
