The study of life
Any living thing
What are the 7 characteristics of life?
The process by which an organism absorbs "foods" to carry out life functions.
The process that changes food into energy that can be used by our cells and our body.
Physical motion, going from one place to another.
Example of Movement
Materials moving through your cells and your body.
Organism respond to their environment and adapt to conditions. If they cannot adapt they will not survive.
Examples of Respondsiveness
1. Skin tans
2. Sweating when we are hot
Getting rid of wastes.
Examples of excretion
4. Exocytosis by cells
5. Salt excretion in plants
Increase in the number or size of cells.
Process by which organisms make more of their own kind
A single parent passes copies of all its genes to each of its offspring.
Example of an organism that does asexual reproduction
Bacteria, protist, hydra
What are the 7 themes of Biology?
1. Structure and Function
Basic unit of life, capable of performing life functions.
All living organisms are made up of one or more _________.
A regulatory process in which an organism regulates its internal environment. Maintaining stable internal conditions by regulating water, temperature, salt, sugar, etc.
A regulatory mechanism that contributes to maintaining a state of equilibrium.
Maintaing constant temperature.
Maintaining constant water levels in the body
Maintaining constant oxygen levels in the body.
The combination of components and processes that serve a common function
Change in a species over time.
Evolution occurs through:
Natural Selection and mutations
The best adapted organisms will survive and reproduce.
Changes in DNA
A group of genetically similar organisms that can produce fertile offspring.
Example of a species
Humans (Homo sapiens)
Passing of traits from parents to offspring
Molecule that carries genetic information about our traits.
Short segment of DNA that codes for a specific protein (trait)/
Organisms in a biological community live and interact with other organisms. Organisms are dependent on one another.
How are humans affecting interdependence of organisms?
Cutting down rainforests, which destroys the natural habitat of many organisms.
Branch of Biology that studies the interactions of organisms with one another and their environment.
Process in which organisms carry out many chemical reactions to get energy.
