Q.20 - Biology

Question

Select two items that biologists agree are necessary in order to consider an organism “alive.” For each, give an example of a nonliving object that otherwise fits the definition of “alive.” 

Step-by-Step Solution

Answer

1. Layers of sedimentary rock have order, but not alive
2. Technology is capable of regulation but it is not alive 

Step1.Introduction

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, adaptation, growth and development, homeostasis, energy processing, and evolution.

Step2. Explanation

Reproduction is a characteristic of a living organism. 

• Rocks are not considered living because they do not have the ability to reproduce because they do not have DNA. Energy processing is the ability of a living organism to process energy for their activities. 
• Metal can be an example of a non-living thing that cannot produce its own energy.
