The taxonomic status of an organism can be changed by changing

Options

A. Anatomy
B. Physiology
C. Morphology
D. Genetic make up

Answer

To solve the question regarding how the taxonomic status of an organism can be changed, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Taxonomic Status**:
- Taxonomic status refers to the classification and nomenclature of an organism. It indicates how an organism is categorized within the biological classification system.

2. **Identify Factors Affecting Taxonomic Status**:
- The question presents several factors: anatomy, physiology, morphology, and genetic makeup. We need to analyze how each of these factors can influence taxonomic status.

3. **Analyze Anatomy**:
- Anatomy is the study of the internal structure of organisms. While anatomical features can provide insights into classification, they can change due to environmental factors. Therefore, anatomy alone does not determine taxonomic status.

4. **Analyze Physiology**:
- Physiology refers to the internal mechanisms of organisms, such as digestion and respiration. Similar to anatomy, physiological traits can also vary with environmental changes and do not inherently change taxonomic status.

5. **Analyze Morphology**:
- Morphology is the study of the external features of organisms. While morphological traits can help in classification, they can also be influenced by environmental conditions and may not be stable indicators of taxonomic status.

6. **Identify the Key Factor - Genetic Makeup**:
- Genetic makeup refers to the organism's genetic composition, including the number and structure of chromosomes. Unlike anatomy, physiology, and morphology, genetic makeup is stable and not influenced by environmental changes. Changes in genetic makeup can lead to speciation and, consequently, a change in taxonomic status.

7. **Conclusion**:
- The taxonomic status of an organism can be changed primarily by changes in its genetic makeup. Therefore, the correct answer to the question is that the taxonomic status can be changed by changing the genetic makeup.

### Final Answer:
The taxonomic status of an organism can be changed by changing its genetic makeup.
