A) X=spherical, y=E.coli
Explanation: I just took the test
The correct answer is option A which is:
X = Spherical; Y = E ColiExplanation:
In this table X is the shape of bacteria whose form is coccus and its associated disease is strep throat. From the form we can say that shape of that bacteria is spherical, Like streptococcus pneumonia.
Y is the bacteria associated with disease. And other information indicates that bacteria is E-coli
Shapes of bacteria divide them into three classes namely coccus, bacillus and spirillum. Coccus bacteria are spherical shaped bacteria. Bacillus have a characteristic rod shape and spirillum are spiral shaped bacteria. Bacteria belonging to each of these classes are causatives of a variety of diseases.
Strep throat is caused by the bacteria belonging to the division coccus. E.coli disease is caused by E.coli bacteria belonging to the division bacillus. . The bacteria Streptococcus Pneumoniae causes pneumonia. Diseases like leptospirosis and syphilis are caused by spirillum bacteria.
