Final answer:
The correct answer is e. all of these are requirements of life, which include the need for water, an energy source, being carbon-based, and having a genetic ancestry demonstrated through DNA similarities.
Step-by-step explanation:
All life on Earth has fundamental requirements that are essential for survival and function. The correct answer to the given question is e. all of these are requirements of life. This includes the necessity for water, which is critical for cellular processes and life functions. Additionally, all living organisms require an energy source to carry out life processes; this energy is often obtained from the environment and converted into ATP (adenosine triphosphate), which is vital for metabolic pathways.
Organisms are also carbon-based, building macromolecules like proteins, nucleic acids, and carbohydrates from carbon-containing compounds. Finally, all life on Earth has a shared genetic ancestry, exemplified by very similar DNA sequences that reflect common evolutionary origins.
