What are characteristics of life?
Any framework capable of performing operations such as eating, metabolizing, excreting, respiration, moving, going to grow, reproducing, and responding to environmental stimulation is defined as living.
Cellular organization, the capacity to reproduce, growth and development, energy use, equilibrium, response to their surroundings, and the ability to adapt are all characteristics shared by all living things. All living creatures will display all of these characteristics.
Order, sensitivity or reaction to the environment, procreation, growth and development, regulation, equilibrium, and energy processing are all shared by all living organisms.
These eight character traits serve to define life when viewed collectively.
Human shivering on a cold day is a natural occurrence that aids in responding to the surroundings.
Thus, the correct option is A.
