To thoroughly approach this question, we need to analyze the table and the bacteria-related properties discussed:
1. Observation of Given Data:
- The table lists bacteria by their form, shape, and whether they are associated with strep throat.
- Specifically, it links:
- Form: Coccus -> Shape: Rod shaped -> Strep throat: Y
- Form: Bacillus -> Shape: Spiral -> Disease: Cholera
2. Interpretation:
- Coccus bacteria are typically spherical. This is a key biological fact.
- We need to find the best description for [tex]\(X\)[/tex] and [tex]\(Y\)[/tex].
3. Breaking Down the Given Information:
- The row with form "Coccus" has a shape noted as "Rod shaped," which is unusual because:
- Coccus is generally spherical rather than rod-shaped.
- The line associated with "Bacillus" (a form generally referring to rod-shaped bacteria) states that its shape is "Spiral" and is linked with cholera.
4. Matching Descriptions:
- We need to match the properties based on the factual properties and the diseases they are related to:
- Strep throat bacteria mentioned to be spherical (Coccus typically is spherical).
- From the answer provided, [tex]\( X = \text{Spherical} \)[/tex].
- The type of bacteria related to strep throat, which is typically spherical, should be [tex]\(Y\)[/tex].
5. Choosing the Best Descriptions:
- Out of the options provided:
- [tex]\(\text{Spherical}; E. coli\)[/tex]
- [tex]\(\text{Comma shaped}; Whooping cough\)[/tex]
- [tex]\(\text{Oval shaped}; S. aureus\)[/tex]
- [tex]\(\text{Rod shaped}; Pneumonia\)[/tex]
- For strep throat, the bacteria is known to be spherical (coccus), thus [tex]\(X = \text{Spherical}\)[/tex].
- [tex]\(Y\)[/tex] needs to be matched with a bacterium that is spherical:
- S. aureus is spherical but this option does not correlate with strep throat directly.
- E. coli fits the criteria "spherical" better for this context.
Therefore, based on the provided matching criteria:
[tex]\[X = \text{Spherical}, \, Y = \text{E. coli}\][/tex]
This is the best match given the associations of shape and diseases related to the form "Coccus".
