The Science of Biology
The Science Of Biology:
· Biology is the study of life
· Biology is formed by the concepts, principles and theories that allow people to understand the natural environment
· There is an order in the natural world
Biologists Study The Interactions Of Life:
· Living things do not exist in isolation: they all contribute to the fragile balance of nature
· Livings things depend on each other and nonliving things
Biologists Study The Diversity Of Life
Biologists Study The Interactions Of The Environment:
· The study of one species always involves the study of another species with which it interacts
Biologists Study Problems And Propose Solutions:
· Biological research can lead to advances in medical treatment and disease
· The study of biology will teach you how humans function and how we fit with the rest of the natural world
Characteristics Of Living Things:
· Sometimes nonliving things have characteristics of living things (i.e. fire)
· An organism is something possesses all of the characteristics of life
· All Organisms:
-have and orderly structure
-produce offspring
-grow and develop
-adjust to changes in the environment
Living Things Are Organized:
· All living things show an orderly structure (organization)
· All living things are
-filled with one or more cells
-contain the genetic material DNA (provides info needed to control the organisms life processes)
-are unified by cellular organization
Living Things Make More Living Things:
· Reproduction (the production of offspring) is the most obvious of all characteristics of life
· It is not essential for the survival of an organism to reproduce
· It is essential for the continuation of a species (group of organisms that can interbreed)
Living Things Change During Their Lives:
· Organisms begin as a single cell
· An increase in the amount of living material and the formation of new structures is growth
· Development is the changes your body undergoes in a lifetime
Living Things Adjust To Their Surroundings:
· Environment is your surroundings
· A condition that requires an organism to adjust is a stimulus
· A reaction to a stimulus is a response
· Adaptation is an important characteristic of a living thing
· Homeostasis is the regulation of an organisms internal environment to maintain conditions suitable for its survival
· Homeostasis occurs in all living things
· Organisms would die without the ability to make internal changes
· Energy is the ability to do work
· Energy makes it possible for all life processes to occur
Living Things Adapt And Evolve:
· An adaptation is anything that enables an organism to respond to a stimulus and better survive
· Adaptations are inherited
· Organisms with the most adaptations are the most likely to survive and reproduce
· Evolution is the gradual accumulation of adaptations
Observing And Hypothesizing
The Methods Biologists Use:
· Scientific methods are common steps that biologists use to gather information and answer
