Consider the table.

Types of Bacteria

\begin{tabular}{|c|c|c|}
\hline Form & Shape & Associated disease \\
\hline Coccus & [tex]$X$[/tex] & Strep throat \\
\hline Bacillus & Rod shaped & [tex]$Y$[/tex] \\
\hline Spirillum & Spiral & Cholera \\
\hline
\end{tabular}

Which best describes X and Y?

A. [tex]$X=$[/tex] Spherical; [tex]$Y=$[/tex] E. coli
B. [tex]$X=$[/tex] Comma shaped; [tex]$Y=$[/tex] Whooping cough
C. [tex]$X=$[/tex] Oval shaped; [tex]$Y=$[/tex] S. aureus
D. [tex]$X=$[/tex] Rod shaped; [tex]$Y=$[/tex] Pneumonia



Answer :

To determine the correct descriptions for [tex]\(X\)[/tex] and [tex]\(Y\)[/tex] in the given table, let's analyze the information systematically.

The table provided is:

[tex]\[ \begin{array}{|c|c|c|} \hline \text{Form} & \text{Shape} & \text{Associated disease} \\ \hline \text{Coccus} & X & \text{Strep throat} \\ \hline \text{Bacillus} & \text{Rod shaped} & Y \\ \hline \text{Spirillum} & \text{Spiral} & \text{Cholera} \\ \hline \end{array} \][/tex]

1. Form Coccus:
- Shape: We need to identify [tex]\(X\)[/tex].
- Associated Disease: Strep throat.

A Coccus bacterium is known to be spherical in shape. Therefore:
[tex]\[ X = \text{Spherical} \][/tex]

2. Form Bacillus:
- Shape: Rod shaped. (Already provided in the table)
- Associated Disease: We need to identify [tex]\(Y\)[/tex].

Bacillus often refers to rod-shaped bacteria, one of the well-known examples being E. coli (Escherichia coli). Therefore:
[tex]\[ Y = \text{E. coli} \][/tex]

So, to summarize, the correct descriptions are:
[tex]\[ X = \text{Spherical}, \][/tex]
[tex]\[ Y = \text{E. coli} \][/tex]

Thus, the choice that best describes [tex]\(X\)[/tex] and [tex]\(Y\)[/tex] is:
[tex]\[ X = \text{Spherical}; Y = \text{E. coli} \][/tex]
