Consider the table.

Types of Bacteria
\begin{tabular}{|l|c|c|}
\hline Form & Shape & Associated disease \\
\hline Coccus & [tex][tex]$X$[/tex][/tex] & Strep throat \\
\hline Bacilus & Rod shaped & [tex][tex]$Y$[/tex][/tex] \\
\hline Spirilum & Spiral & Cholera \\
\hline
\end{tabular}

Which best describes [tex][tex]$X$[/tex][/tex] and [tex][tex]$Y$[/tex][/tex]?

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



Answer :

To solve this question, let's carefully analyze the given table of bacteria types and their associated information.

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

1. For the form "Coccus," which is linked to "Strep throat," we need to determine what shape [tex]\( X \)[/tex] represents:
- The term "Coccus" is commonly used to describe spherical-shaped bacteria. Thus, the best description for [tex]\( X \)[/tex] is "Spherical."

2. For the form "Bacilus," which is labeled as "Rod shaped," we need to figure out the associated disease [tex]\( Y \)[/tex]:
- One disease commonly associated with rod-shaped (bacillus) bacteria is pneumonia. Bacteria such as Klebsiella pneumoniae and Haemophilus influenzae, which are rod-shaped, can cause pneumonia. Therefore, the best description for [tex]\( Y \)[/tex] is "Pneumonia."

With these descriptions, we find:
- [tex]\( X = \text{Spherical} \)[/tex]
- [tex]\( Y = \text{Pneumonia} \)[/tex]

Comparing these with the options provided:
1. [tex]\( X = \text{Spherical} \)[/tex]; [tex]\( Y = \text{E. coli} \)[/tex]
2. [tex]\( X = \text{Comma shaped} \)[/tex]; [tex]\( Y = \text{Whooping cough} \)[/tex]
3. [tex]\( X = \text{Oval shaped} \)[/tex]; [tex]\( Y = \text{S. aureus} \)[/tex]
4. [tex]\( X = \text{Rod shaped} \)[/tex]; [tex]\( Y = \text{Pneumonia} \)[/tex]

The correct choice that matches our descriptions is:
- [tex]\( X = \text{Spherical} \)[/tex]; [tex]\( Y = \text{Pneumonia} \)[/tex]

Therefore, the best answer is:

[tex]\( X = \text{Spherical} \)[/tex]; [tex]\( Y = \text{Pneumonia} \)[/tex]
