Consider the following information. chimpanzees have a tibia (shin bone), whose upper end is "t" shaped, as it does not have to support their entire body weight. the "t" shaped tibia is an ancestral characteristic shared by most primates. humans and members of the genus australopithecus, a fossil primate, have a "y" shape to the upper tibia, capable of supporting the full body weight, and evidence of bidpedalism. the "y" shaped tibia is a recent evolutionary adaptation, or a derived trait. additionally, australopithecus shares an ancestral small cranium with chimps and gorillas, while humans have a derived large cranium. you design a phylogenetic tree based on the information describe above. what type of approach have you employed in your classification scheme?
a) traditional approach.
b) cladistic approach.

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.

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
