Flowers of orchid species ophrys bombyliflora look and smell like female bumblebees. this attracts the male bumblebees flying nearby to the flowers. thus, pollen sticks to the head and abdomen of the bumblebee, which causes pollination. this orchid species is only pollinated by these bees, which is why the species is known as bumblebee orchids. what mode of evolution is represented by this example?

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.

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.
