cell
structure formed from specific molecular patterns
Order
formation
of new individuals
Reproduction
increase in size and figure
Growth and development
chemical and physical changes taking place in an organism
Energy processing
maintenance of nearly constant condition within an organism
Regulation
react to a stimulus that results to movement
Response to the environment
a process in which organism slowly or rapidly becomes
better suited to its environment to survive
Evolutionary adaptation
What are the theories on the origin of life
spontaneous generation
primordial soup
states that living things originated
spontaneously from nonliving matters such as the dust created fleas, and maggot
arises from meat
spontaneous generation
states that
chemical reactions of primordial gases such as methane, ammonia, water, carbon
dioxide, and hydrogen sulfide, as caused by the energy coming from geothermal heat, sunlight, and lightning, catalyze the creation of organic compounds, which
is essential for the genesis of life.
primordial soup
biomolecules are made up of four elements
carbon
oxygen,
hydrogen
nitrogen
Protein link becomes established
