What do you expect the activity to be of a mutant p53 with ser20 converted to aspartate--would it likely have no activity, partial activity, wild type activity, or more activity than the wild type? g

it's c. (to reduce the greenhouse effect/carbon gasses)

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
