A scientist observes a new species exhibiting metabolism, growth, and reproduction. However, it lacks the ability to maintain homeostasis. Can this species be definitively classified as living? Explain your reasoning.
Yes, metabolism, growth, and reproduction are sufficient to define life.
No, homeostasis is a fundamental characteristic of life, crucial for maintaining internal stability in response to external changes.
Maybe, further research is needed to determine if other life-defining characteristics are present.
It depends on the specific definition of life being used.
