Match the following

(1) Likely found in an autotroph
(2) H antigen
(3) counterclockwise rotation of flagella/flagellum
(4) PHB granule

(A) pili
(B) produces "tumbles"
(C) flagellum
(D) carboxysome
(E) LPS layer
(F) glycogen storage
(G) lipid storage
(H) produces "runs" towards an attractant

(1) Likely found in an autotroph - carboxysomes

(2) H antigen - flagellum

(3) Counterclockwise rotation of flagella/flagellum - produces “runs” towards an attractant

(4) PHB granule – glycogen storage

Explanation:

Autotrophic bacteria contain microcompartments called carboxysomes. These are protein subunits containing enzymes which involve in carbon dioxide concentration or fixation mechanism.

H antigen is the protein found in the thread-like slender filaments of the flagella.  

Counterclockwise rotation of the flagella produces “runs” or a swimming movement which facilitates bacterial walk or movement.

PHB – photohydroxybutyrate molecules are the biopolymers produced by bacteria when carbon nutrients like glycogen granules are available in excess and convert them to carbon storage reserves.  

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.
