Which strand and process correctly describe Strand C in the model? Strand Cis DNA. Strand C is part of DNA replication.
Strand C is tRNA. Strand C is only involved in translation.
Strand C is mRNA. Strand C is involved in transcription and translation.
Strand C is DNA. Strand C is involved only in transcription.

I'm pretty sure that strand C is mRNA.

Explanation:

This is basically a diagram of the Central Dogma theory of DNA which states how DNA is read in your body. If we're looking at Strand C then you can automatically cancel out the first and the last, because it isn't DNA. DNA is only in the first part of Central dogma, where it's transcripted into RNA. So this is either mRNA (messenger riboneucleic acid) or tRNA (transfer ribonucleicacid). I think it's mRNA because it is also being transferred into (the last part), which means it's involved in Transcription and Translation.

d. organisms have cells with different shapes and functions.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
