How many characteristics are used to describe living things?

Answer 1

These 8 characteristics must be present:

1.Composed of Cells

2.Grow and Develop

3. Regulate their Metobolic Processes

4. Respond to Stimuli

5.Reproduce

6. Change over time

7. Ability to obtain and use energy

8. Have homeostasis

Answer 2

It is not always an easy thing to tell the difference between living, dead, and non-living things. Prior to the 1600's many people believed that nonliving things could spontaneously turn into living things. For example, it was believed that piles of straw could turn into mice. That is obviously not the case. There are some very general rules to follow when trying to decide if something is living, dead, or non-living. Listed here are the six rules used by scientists:

Living things are made of cells. (Organization)

Living things obtain and use energy. (Energy)

Living things grow and develop. (Growth and Development)

Living things reproduce. (Reproduction)

Living things respond to their environment. (Responses)

Living things maintain homeostasis. (Homeostasis)

If something follows one or just a few of the rules listed above, it does not necessarily mean that it is living. To be considered alive, an object must exhibit all of the characteristics of living things. Sugar crystals growing on the bottom of a syrup container is a good example of a nonliving object that displays at least one criteria for living organisms.

Answer 3

To be living, an organism must be able to do, or have, All of the following at least once:

• made of at least one cell
• made of water and carbon
• genetic material
• metabolism-- ***ingestion, digestion, respiration, excretion
• have movement-- internal, internal, grow
• reproduce~sexually (two organism) or asexually (by itself)
• maintain homeostasis~respond to environment or stimulus and maintain a safe internal / external environment

***The Four Parts of Metabolism:

• ingestion~ take in food
• digestion~ break food into energy
• respiration~ use energy
• excretion~ get rid of waste

Answer 4

Actually, there's seven. And all seven are required to be considered living. They must adapt to their environment, reproduce, grow, respond to their environment, exchange gasses, waste removal, and the take in of substances from around their habitat.

Answer 5

seven (movement, respiration, sensitivity, feeding, excretion, reproduction, growth)

Answer 6

the answer is 6
