Answer;
D. Rift valley
Explanation;
-A divergent boundary also called the divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Most divergent plate boundaries are underwater (Iceland is an exception) and form submarine mountain ranges called oceanic spreading ridges.
-Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys.They are constructive boundaries. Convergent boundaries on the other hand are areas where plates move toward each other and collide.
Answer:
Blood is carried away from the heart by arteries. Blood that is rich in oxygen. Blood that is low in oxygen is returned to the heart by veins. there is more pressure in arteries than in veins.
Endocrine system regulation slowly happens but produces long-lasting effects, whereas nervous system regulation quickly takes place with short-term effects.
Endocrine system can regulate many things in the body that control the metabolism. The effect shouldn't be instant, but it should be good for long term effect. Nervous system need a much faster reaction because it responsible for "fight or flight" reaction. A slow nervous system will cause the organism caught by predator easier.
