For pearlite, the two phases are present as alternating layers. A -ferrite matrix surrounds cementite particles that are extremely small and parallel and have the shape of needles.
Is pearlite a bainite ?
The primary distinction between bainite and pearlite is that the latter has a microstructure resembling plates while the former has alternating layers of cementite and ferrite.
Two distinct microstructures of steel are referred to by the names pearlite and bainite. These formations develop as a result of altering the temperature of austenite.
A form of steel microstructure known as pearlite comprises a two-layered phase made up of alternating layers of cementite and ferrite. When austenite cools down to below its eutectoid temperature (727 °C), it crystallizes. Also, cast iron and steel have similar structure. On the other hand, Bainite is a form of steel microstructure with a structure like a plate. Between pearlite and bainite, the structure is where the biggest differences lie. Additionally, when austenite cools, bainite develops until it reaches a temperature where austenite structure is no longer stable (thermodynamically unstable). Additionally, similar construction may be seen in steel as well.

Answer:
A. They also help the environment by refreshing the air and by reducing smog and effects to the ozone layer.
Explanation:
The author makes a claim that environment is refreshing by the air and the effects on ozone layer are reduced. This statement is not supported by the evidence. The ozone layer is polluted by the environment pollution. The pollution created by humans is also affecting the air which ultimately pollutes the ozone layer.

I would say that being anti-racist does not describe America after the abolition of slavery. For decades, up until maybe the 60's African American's were mistreated with things like Jim Crow Laws, that were stopped some time in 1964. While this had ended segregation it most definitely did not end racism. Even now hate groups, like the KKK, are very prominent in America, with over 1,000 recorded in 2018.
