Define the 7 characteristics of living things and give (2) examples for each

Solution

Answer:

Seven characteristics of life:

1. Cell & Organization: heart functions with pericardical muscle organization & brain functions with neuronal cell organization

2. Energy use and metabolism: metabolic reactions in liver derive energy for muscle e& heart function

3. Response to environmental changes: neuronal sensory & motor perceptions & sensations from the sense organs are mediated by both visceral nervous system and spinalchord.

4. Regulation and homeostasis: negative feedback mechanism and positive feed back mechanism maintain body homeostasis via excretory organs & hormone release from pituitary

5. Growth and development: reproduction & transcription via gene epression synthesize proteins finally to mediate growth with mineralization of bones

6. Reproduction: hormones and sex steroids inside the body mediate reproductive functions finally to generate new offspring

7. Biological evolution: new traits are naturally selected as an evolutionary adaptation for evolution of living organisms
