This is one reason that the same hormone can trigger different effects in different tissues. For example, epinephrine binds to four different receptors in different tissues-- eliciting a different response from each.
Technology, since the 19th century, has very much helped the development of Scientific theories. It has helped Scientists use telescopes to look into germs or zoom into the stars, it has also helped Chemists determine the weight of, say, a mashed up apple with soda.
Continuously facing towards the east also helps the flowers to heat up quickly. This gives them an advantage in pollination, as warm flowers attract insects. Therefore, in the plant's interest, the flower always faces the sun and is therefore always clearly visible to these important pollinators.
Answer:
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.
Explanation:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
