Living organisms interact in a variety of ways for a variety of purposes. the imperial shrimp rides on sea cucumbers as they travel underwater. this interaction enables the shrimp to use little to no energy to move between the areas in which it feeds. the sea cucumber is typically unaware that the shrimp is using it for transport.  which type of interaction occurs between the imperial shrimp and its host organism?   mutualismcommensalism  parasitism  competition

Commensalism.

Explanation:

Commensalism is a type of  biological interactionin which one species is benefitted and the other species is neither benefitted nor harmed. This is a type of positive interaction.

The shrimp uses sea cucumber for their movement of water and uses their energy whereas sea cucumber is unaware of this interaction. Hence, it is commensalism in which shrimp is benefitted but sea cucumber is neither harmed not benefitted.

Thus, the correct answer is option (2).

answer; (phospholipid);

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
