1. a. The property or quality that distinguishes living organisms from dead organisms and inanimate matter, manifested in functions such as metabolism, growth, reproduction, and response to stimuli or adaptation to the environment originating from within the organism.
What is life in biology short answer?
Life is a unique, complex organisation of molecules expressing itself through chemical reactions which lead to growth, development, responsiveness, adaptation and reproduction.
What is a simple definition of biological?
Definition of biological 1 : of or relating to biology or to life and living processes. 2 : used in or produced by applied biology. 3 : connected by direct genetic relationship rather than by adoption or marriage her biological father.
What is the purpose of biological life?
All life forms have one essential purpose: survival. This is even more important than reproduction.
What are the defining characteristics of biological life?
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life.
What is the basic of life?
Cells are called as the basic unit of life because all the living organisms are made up of cells and also all the functions taking place inside the body of organisms are performed by cells. Cells provide the specific conditions, for the occurrence of the metabolic reactions.
What was the first form of life?
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old. The signals consisted of a type of carbon molecule that is produced by living things.
What is the life process?
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction. In humans, who represent the most complex form of life, there are additional requirements such as growth, differentiation, respiration, digestion, and excretion. All of these processes are interrelated.
What is biological and example?

Being alive enhances our ability to empathize. It allows us to connect and support others because of our good and bad experiences and how other people, family, and friends stood for us in difficult situations and circumstances.
Are humans biological organisms?
In most biological respects, humans are like other living organisms.
What are the 7 characteristics of life biology?
Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits.
What are the 5 main characteristics of life?
- Homeostasis = The maintenance of a relatively stable internal environment.
- Reproduction = The ability to form a new offspring.
- Metabolism = The ability to obtain and use. energy for growth and movement.
- DNA/Heredity = Genetic material that is passed on during reproduction.
What are the 7 properties of life?
The seven characteristics what makes an organism living are: Environmental responses, cells, change and growth, reproduction, having complex chemistry, and homeostasis and energy processing. Sometimes non-living things can portray some of the above characteristics, but a living being consists of all.
What are biological principles?
Biological principles are based on the fundamental concept that all living organisms are similar in composition, growth, heredity, reproduction, metabolism, and homeostasis. 5. What are the three biological principles? Variation, selection, and heredity.
What is life one word?
the animate existence or period of animate existence of an individual: to risk one’s life; a short life and a merry one. a corresponding state, existence, or principle of existence conceived of as belonging to the soul: eternal life.

Where did all life come from?
All life on Earth evolved from a single-celled organism that lived roughly 3.5 billion years ago, a new study seems to confirm. The study supports the widely held “universal common ancestor” theory first proposed by Charles Darwin more than 150 years ago.
What started life?
Many scientists believe that RNA, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.
What started life on Earth?
It seems possible that the origin of life on the Earth’s surface could have been first prevented by an enormous flux of impacting comets and asteroids, then a much less intense rain of comets may have deposited the very materials that allowed life to form some 3.5 – 3.8 billion years ago.
How many life processes are there?
There are six life processes that all living organisms perform. They are movement, respiration, growth, reproduction, excretion and nutrition.
What are life process give example?
Answer: Life processes are defined as all the metabolic processes that occur in a living being and fulfill all the basic needs. Examples of Life processes: Growth, nutrition, digestion, respiration, transportation, excretion, reproduction, and mobilization etc.
What happens if there is no life process?
if all organisms stop the process of reproduction then there will be no more generations after this organisms and thus these organisms will be the last generation of this world and after the death of these organisms there will be no life left on this planet and thus the Earth will be destroyed because no daily life …
