The image shows a paramecium and a bacterium. one of these organisms is very good at rapidly adapting to environmental changes because it has the ability to take in stray genetic information from the environment. which structure allows the organism to do this?

That would be the Bacterium I believe. Because they can come in contact with other bacteria absorbing their genetic information through what is called conjugation. As to the which structure part that would be 5 the DNA coiled into nucleotides

The correct answer will be pili.

Explanation:

Bacteria have the capability to take DNA from the environment through a process called transformation.

This uptake of DNA through the cell membrane by a competent bacteria is common in gram-positive bacteria but gram-negative bacteria require extra type IV pili protein tubes which originate from the cytoplasmic membrane.

Thus, pili are the correct answer.

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.
