Quartzite forms when magma presses against preexisting rock. heat and pressure change the rock. quartzite is formed from

The answer is contact metamorphism. Quartzite is formed from sandstone which is usually grey or white in color while quartzites range in shades of pink to red depending on the amount of iron oxide in the stone. Other colors are brought about by other minerals present in the rock. The sandstone is usually a sedimentary rock but after the metamorphism the structure is different and the layers cannot be discticitve.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells

answer;

a. sheep consumption efficiency would be reduced.

explanation;

-trophic efficiency is a measure of how much energy occurs at one level divided by the energy at the level immediately below it . trophic efficiency incorporates three types of efficiency:

-the proportion of available energy that is consumed (consumption efficiency).   it is the proportion of the available biomass that is ingested by consumers.

-the proportion of ingested food that is assimilated (assimilation efficiency).

-the proportion of assimilated food that goes into new consumer biomass (production efficiency).

-in this case, the grasshoppers would affect sheep by reducing the proportion of the available biomass that is ingested by the sheep.
