Honor Bio Test 1 Flashcards
3 Unifying themes of biology
Diversity and unity of life, Interdependence, and evolution
1st step of the scientific process
Make an observation
2nd step of scientific process
form a hypothesis
3rd step of scientific method
Make a prediction
4th step of scientific method
perform an experiment
5th step of S M
Make a conclusion
6th step
COMMUNICATE
Compound light microscope
has 2 lenses
images appear backwards
Resolution
the power to show details clearly
Convex lense
a converging lens that refracts rays
objective lens
closest to the object
Electron microscope
it uses a beam of electrons which produces an image of the specimen placed in a vacuum chamber
how biology affects our daily life
it determines what foods we eat are healthy, and how much to exercise to stay healthy
how biology can affect our society
It can tell us how to control animal populations and help us with problems such as pollution
The 7 characteristics of life
Response to Stimuli, Homeostasis, metabolism, organization of cells, reproduction, change through time,growth and development
Response to Stimuli
How we react to physical/chemical changes in the surroundins
Metabolism
the sum of all the chemical reactions we have that transform into energy
Homeostasis
The maintenance of a stable level of internal conditions as environments change
Growth and developement
the increase in size and maturity
Organization of cells
Everything that lives is made up ofcells
reproduction
keeping the species alive
change through time
evolution/slowprocess
How metabolism would affect homeostasis
Metabolism is what helps maintain homeostasis
natural selection
not every living thing is created = . Natural selection is the decision of who is the strongest. “survival of the fittest”
