Question: 1 / 715

What does the term 'viable' refer to in biological contexts?

Capable of reproducing successfully in various environments

Capable of surviving or living successfully, especially under particular conditions

The term 'viable' in biological contexts primarily refers to an organism's ability to survive or live successfully, especially under specific conditions. This definition encompasses a variety of factors influencing an organism's survival, including the availability of resources, environmental conditions, and the organism's inherent traits. Viability implies that the organism can maintain its life processes and potentially reproduce, ensuring the continuation of its species.

While options discussing reproduction and growth are related concepts, they do not capture the full scope of what viability entails. Viability emphasizes the mere ability to exist and sustain life rather than focusing solely on reproduction or growth rate. Thus, in biological settings, describing an organism as viable highlights its capacity to live and thrive in its environment, often under certain conditions that are crucial for survival.
