A sample known to be one of the four listed in the table was heated to a temperature of 35C but remained a solid. The sample was found to have a density greater than 6 g/cm3and to be a good conductor of electricity. Burning the sample produced a blue flame. Based on this information, what is the identity of this sample?

The pressurized plants and fungi mentioned in the video have some surprising similarities. what differences would you expect them to have?

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary

Why do the circulatory systems of land vertebrates have separate circuits to the lungs and to the rest of the body?
