students learned that objects can exert forces on other objects without touching. which 3 investigations will provide evidence to support what they have learned? a measuring how close a soda can must be before it rolls toward a balloon that has been rubbed on someone's hair b counting the number of staples that are directly attached to a strong magnet c dropping a rubber ball from a distance of 1.5 meters above the classroom floor d placing a magnet against a jar containing a mixture of iron filings and sand e measuring how far a toy car travels across the floor before coming to a stop

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

the answer is c a tornado

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.
