Which statement would most likely be in agreement with Lamarck's theory of evolution?A)Black moths have evolved in an area because they were better adapted to the environment and had high rates of survival and reproduction. B)Geographic barriers may lead to reproductive isolation and the production of new species. C)Giraffes have long necks because their ancestors stretched their necks reaching for food, and this trait was passed on to their offspring. D)Most variations in animals and plants are due to random chromosomal and gene mutation.

relationships play a major role in a human's emotional and mental wellbeing. healthy relationships with the people around you are even linked to a smaller production of cortisol, a stress hormone.

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.
