The graph above was made by a biologist working in the Galapagos islands. The biologist examined the stomach contents of the
ground finch, the leaf finch, and the cactus finch, to determine what foods they usually ate. The graph shows the average number
of seeds of the 4 most common plant species found in the stomach of each type of bird
Based on the graph, which statement is correct about the relationship between the ground finch and the cactus finch?
A)
Neither species of finch has diet similarities to the leaf finch
B)
Ground finches and cactus finches mostly occupy different feeding niches.
C)Ground finches and cactus finches probably compete strongly for cactus
seeds
D)Daisy seeds make up a large portion of the diet of both types of finch, so
they both occupy the same finch

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.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
