Peptic ulcers are sores in the lining of the stomach that is caused by a bacterial infection. These bacteria increase the acid in the stomach and eat away at the stomach lining, which causes sores. When this occurs, which type of tissue does the acid remove?

by drinking easy

very easy

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

i believe the answer would be b. hope it : )

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
