What feature is unique to yersinia pestis when compared to other yersinia species?
a- motile
b- capsule
c- spore forming
d- can grow in the presence of oxygen

B-Capsule

Explanation:

Bacteria from Yersinia genus don't develop capsules, but Yersinia pestis has the exception. Y.pestis develops a similar structure to a capsule.

Other options are true for Y.pestis and all Yersina genus.  Despite the fact that someones can lose their motility in a stage of their life cycle, these bacteria are motile. Also, they are facultative anaerobic organisms and they don´t form spores.

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
