OLEGan [10]

Answer:

c. Magma composition and cooling rate.

Explanation:

A rock cycle can be defined as a concept used to describe the continuous process that leads to a rock's creation, formation, transformation from one form to another, destruction and reformation over a specific period of time. The natural phenomenons that influences the rock cycle are weathering, plate tectonic activity, erosion, etc.

Basically, the three (3) main types of rocks are; metamorphic rock, sedimentary rock and igneous rock.

All igneous rocks are produced from magma (lava) and formed at the Earth’s surface, thereby, causing them to have a coarse texture and dark colors.

Generally, the cooling and solidification of magma (lava) leads to the formation of an igneous rock, either when the melted rock is still inside the continental crust of the Earth or at volcanoes on the Earth's surface.

Hence, magma composition and cooling rate determines the type of igneous rock that forms from magma. Some examples of an igneous rock are granite, obsidian, tuff, basalt, rhyolite, andesite, pegmatite, dacite, scoria, pumice, etc.

As the cyanide blocks the bindinge site for oxygen, which is normally reduced to water, the pumping of hydrogen from the matrix into the space between the mitochondrial membrane decreases and finally stopps. There is an accumulation of electrons and the components of the respiratory chain are completely reduced, therefore the respiratory chain stopps working.
