The movement of tectonic plates buries a rock deep inside earth. intense heat and pressure change the mineral composition of the rock and transform 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 sediment. rock b has a fine grainy texture and small crystals.

Question 14(Multiple Choice Worth 3 points)

(04.01 HC)  

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 one!

(Proof of the test) :) FLVS right?

Any one who is from FLVS say thxs or add me or just 5 star rate

it has one origin of replication, but it proceeds in two directions - d)

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
