Question

i. designed by nature
a. biomimicry in architecture

1. the spiral is a beautiful, universal shape: a curve that winds outward from a fixed point.

i. in nature, a spiral design is prominent in animals with shells.
ii. in architecture, the staircase mirrors the intricate pattern of a nautilus shell.
iii. modern parking garages and buildings use the natural beauty of the coiling spiral in their construction.
iv. the design offers a space - saving feature as well—circular stairs and ramps take up less space than traditional horizontal structures.
what features show this is an example of scientific writing?
∘ it includes concrete evidence and examples.
∘ it uses quotes from historians.
∘ it is entertaining and provocative.
∘ it tells about what happened long ago.

Explanation:

To determine the features of scientific writing, we analyze each option:

• The first option: The text provides concrete examples (e.g., spiral in shelled animals, staircase mirroring nautilus shell, modern buildings using spiral) and evidence (space - saving feature of circular stairs/ramps). Scientific writing often uses concrete evidence and examples to explain concepts.
• The second option: There are no quotes from historians in the text.
• The third option: The text is not focused on being entertaining or provocative; it's explaining a scientific concept (biomimicry in architecture).
• The fourth option: The text does not discuss events from long ago.

So the correct option is the one about including concrete evidence and examples.

Answer:

It includes concrete evidence and examples.
