Answer:
They open the stomata during the day to collect light energy from the sun and carbon dioxide from the atmosphere, i.e adaptation.
Explanation:
Plants also responds to hormones such as abscisic acid that causes the stomata to close during stressful conditions. During the day the mesophyll in a leaf requires the stomata to open for exposure to sunlight and carbon dioxide. It closes at night when there is no sunlight to prevent water loss through transpiration in response to the turgidity of guard cells.
Because of the property of paleomagnetism, iron rich rocks show the location of magnetic poles at the time of their formation.
Paleomagnetism is concerned with the study of materials that have a record of the earth's magnetic field due to the content of magnetizable material within them. As iron is easily magnetized, materials with a high iron content are likely to indicate the nature of the magnetic field of the earth when they are formed.
Answer: few animals can undergo both.
