Physical change: by cutting the three it went to small logs. This is a change of shape and size, which didn't chaghe the chemical consitutution (molecules). It still is made of the same compounds of the original three. That is why this is a physical change.
Chemical change: By firing the logs the organic matter went into a combustion reaction, which is a chemical change: Organic matter + O2 at hight temperature -> CO2(g) + CO(g) + H2O(g).
Proteins perform numerous functions in the cell membrane, one of which is to regulate the movement of materials, atoms of elements and other ions as they are entering and exiting the cell. These proteins that play this significant role, would be classified as transmembrane proteins, which are specific kind of intergral proteins.
The answer is commensalism.
<span>Commensalism is a relationship between two organisms in which only
one of them has benefit, and the other one is not affected. In this example, the Great Burdock's plants spread their seeds using animals, so they benefit from this relationship. On the other hand, animals neither have benefits not are harmed from the relationship.
Therefore, the relationship between </span><span>the Great Burdock plants and animals is the example of commensalism.</span>

The correct answer is parasitism.
Parasitism, in the field of evolutionary biology, refers to an association between species, where the parasite, the organism, lives on or in another species, the host, creating some kind of harm in it, and is amended structurally to this way of life.
The parasites include protozoans, like as the agents of sleeping sickness, malaria, and amoeba dysentery; animals, like lice, hookworms, mosquitoes, and vampire bats; fungi, like the agents of ringworm, honey fungus; and plants, like dodder, mistletoe, and the broomrapes.
