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]
