At the place marked with the letter A we have a divergent plate boundary. On this type of boundary, the plates are moving away from one another. As they move away, they leave a gap behind them, and the crust is becoming thinner and thinner with lots of cracks in it. Because of that, the high pressures from the mantle manage to push upwards the magma with ease. The magma reaches the seafloor and it is pushing the crust upwards until it breaks it. As the magma pushes the crust upwards,underwater volcanoes are formed, and when the crust is broken by the magma, the magma flows get on the seafloor, cool of very quickly in the water, and create new crust.
Answer:
The building blocks of proteins are amino acids, which contain elements such as H,N,O,C , and more. They are the monomers of the proteins. So, the monomer will be the amino acids, and the polymer will be the proteins themselves
Explanation:
The correct option is C.
Scientists believed that the earth tectonic plates are in constant motion, this motion is slow and its rates vary. The motions of the tectonic plates are caused by the convection current which is found in semi molten mantle. The convection current are created by heat within the earth surface. When a semi molten rock is heated, it become less in density compared to its surrounding and thus rises up. When the less dense molten rock reaches the crust above, it spread out and carries the tectonic plate above with it. When the molten magma cools down, it sinks and the whole process is repeated leading to continuous movement of the tectonic plates.
The answer is D.
DNA must be turned into RNA in order to leave the nucleus.
Good luck! :)
