• A) 0.20
• B) 0.10
• C) 0.087

Definitions:

Physical Conditions

The various aspects of the environment that can influence living organisms, such as temperature, humidity, and air quality.

Chemical Conditions

Refers to the specific chemical environment or parameters that influence the behaviour and state of a substance or system.

Convergent Evolution

The evolutionary process where organisms not closely related independently evolve similar traits due to having to adapt to similar environments or ecological niches.

Distantly Related

Distantly related organisms share a common ancestor far back in their evolutionary history, indicating they are part of different subgroups within a broader taxonomic category.
