1. Based on the assumptions above, in the mammalian genome, how many total base pairs are in all the mammalian genes? Show your math (2 pts). 10,000 * 10,000 = 100,000,000 There are 100,000,000 total base pairs in mammalian genes. 2. What percentage (%) of the total genome does this represent? Show your math (2 pts). 100,000,000/3,000,000,000 * 100fi = 3.33fi 3. What is the chance (%) that a random mutation will occur in any given gene? Show your math (2 pts). 4. Only 1 out of 3 mutations that occur in a gene result in a change to the protein structure. What is the probability that a random mutation will change the structure of a protein? Show your math (2 pts).

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .

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.

not: both offer magnification to the atomic level.
