A 12-year-old boy is brought to the clinic for progressively worsening blurry vision and generalized headaches that are worse in the morning. On further questioning, he is also revealed to have nausea, joint pain, itchy and peeling skin, dizziness, and irritability. Historically, he has been a healthy child and his family follows an organic diet with additional supplements that include 2 tablespoons of cod liver oil and a multivitamin tablet a day. On exam, his weight dropped from the 50th percentile a year before to the 10th percentile currently. He has oily skin and hair and cracking at the corners of his mouth. Chronic overdose of which of the following most likely caused his symptoms

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

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.

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
