The water buttercup produces thin leaves underwater, but those same tissues will produce broad leaves above the water. individuals in the 1800's (when hunger and childhood diseases were common) averaged slightly over five feet tall, but their offspring in the 1900's were substantially taller on the average. these traits are:

These traits are referred to as environmental factors on gene expression

type of trait.

These are characteristics or features an organism has as a result of different

factors such as the following

The environmental factors such as hunger and childhood diseases made the

height of individuals to be lower in the 1800s.

Environmental factos on gene expression

Explanation:

The water buttercup produces thin leaves underwater, but those same tissues will produce broad leaves above the water. individuals in the 1800's (when hunger and childhood diseases were common) averaged slightly over five feet tall, but their offspring in the 1900's were substantially taller on the average. these traits are environmental factos on the ability of genes to express themselves.

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.
