HELP QUICK! URGANT Read the following passage:

The movement of tectonic plates buries a rock deep inside Earth. Intense heat and pressure change the mineral composition of the rock and transform it into Rock A. Rock A melts and comes out to the surface of Earth during a volcanic eruption. The molten rock cools rapidly to form Rock B.

Which statement is most likely correct?

Rock B may have fossils.
Rock A may have shiny, glassy surface.
Rock A is composed of layers of sediments.
Rock B has a fine grainy texture and small crystals.

this would be a math

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project

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.
