Scientists have been concerned for several years about the bee population dying off. there are several theories about why their population is being reduced. one of these theories is that the pesticides being sprayed onto plants are killing them. which is the best solution to this problem? a) continue to use harsh pesticides to grow food. bees are not vital to the ecosystem. b) ask scientists to create a genetically modified bee that is unharmed by harsh pesticides. c) encourage farms that produce food to only use organic pesticides that do not have as harmful effect on the bees. d) completely stop the use of all pesticides regardless of the effect this has on our food supply, and monitor the bee population to see if they start to come back.

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.
