What are the characteristics of Life?
-Made up of cells -Grows and develop -Exhibits metabolism -Capability to reproduce -Responds to their environment -Maintain Homeostasis
These discipline are connected to one another, through which biologists call?
Unifying themes
Biological system
an organized group oh interacting parts
A system
It includes organs that interact
Body System
It includes living things and nonliving things that interact
Ecosystem
It is the basic unit of life
Cell
Living things cannot live alone, their survival depends how they interact with the environment.
Interaction with the environment
interactions of living organism with one another and their environment
Ecology
Living organisms use a source of energy for their metabolic activities
Energy and Life
Living organisms that capture light and energy to convert it into chemical energy in food
Autotrophs
Give three examples of Autotrophs
Plants, Brown Algae and Cyanobacteria
Living organisms that use chemical energy stored in molecules obtained from food
Heterotrophs
Give five examples of Heterotrophs
Human, Tiger, Fungi and Tape worm
Organism’s structures fit with its functions
Form and function
The traits of Parents being passed from one generation to another
Reproduction and inheritance
Organisms must maintain homeostasis to survive inn diverse environment
Regulation
The maintenance of constant internal conditions
Homeostasis
Give two examples of regulation
Blood distributing heat throughtout the bodyand evaporation of water helpsregulate body temperature
More examples of regulation
Kidneys maintain water balance in the body & Pancreas regulates blood sugar level
Living organisms survive depending on how one will adapt to its changing environment
Adaptation
The genetic makeup of a population of species changes. It is develooped and diversified. It accounts for both the diversity and the unity of life
Evolution
The field of science is changing the lives of all organisms through research
Biology and Society
