Which of the following features are not shown by scientific names of various organism?

Options

A. They consists of two components
B. They have Latin origin
C. They always have ''linn'' abbreviation at the end of second component
D. They are printed in italics

Answer

To determine which features are not shown by scientific names of various organisms, we need to analyze the characteristics of scientific nomenclature. Here’s a step-by-step breakdown:

### Step-by-Step Solution:

1. **Understand the Structure of Scientific Names**:
- Scientific names are composed of two parts: the genus name and the species name. This is known as binomial nomenclature.

2. **Language of Scientific Names**:
- Scientific names are typically derived from Latin or are in Latin form. This is a standard rule in taxonomy.

3. **Formatting of Scientific Names**:
- When printed, scientific names should be italicized. If written by hand, they should be underlined to indicate their Latin origin.

4. **Examine the Options**:
- Now, let’s look at the options provided in the question:
- **Option 1**: They consist of two components (genus and species) - This is correct.
- **Option 2**: They have Latin origin - This is also correct.
- **Option 3**: They always have "Linn" abbreviation at the end of the second component - This is incorrect. The "Linn" abbreviation refers to the scientist Carl Linnaeus, who developed the naming system, but it is not a feature of all scientific names.
- **Option 4**: They are printed in italics - This is correct.

5. **Conclusion**:
- The feature that is not shown by scientific names is the requirement for "Linn" abbreviation at the end of the second component. Therefore, the answer is the option that states this incorrect feature.

### Final Answer:
The feature that is not shown by scientific names of various organisms is that they always have "Linn" abbreviation at the end of the second component.
