How have submersibles benefited ocean exploration? a. they allow exploration of arctic waters. b. they reduce the expense of ocean exploration. c. they allow the deep ocean to be explored. d. all of the above

Correct C). They allow the deep ocean to be explored.

Due to the development of submarine technology like a submersible, the deep sea exploration is possible. Previously it was hard to believe that in the deep sea life exist, but due to the development of submersible, it showed that it is possible. It enabled the scientist to advance their studies in the field of deep sea surveying, marine ecology etc.

Hence, the correct answer would be option C

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
