Flashcards in Introduction Deck (35):
What is the Scientific Method?
A way of answering a scientific question or problem.
What is Biology?
The study of living things.
What are observations?
Data we collect using our senses.
What is a Qualitative observation?
information that uses descriptions.
What is a Quantitative observation?
information that uses numbers and measurements.
What is a Hypothesis?
A possible explanation to a scientific question or observations
What is an experiment?
An organized way to test a hypothesis.
What variable is changed deliberately by the experimentor?
Which variable is the result (response) to what you are testing?
Which variable is used as a comparison, to prove your results are due to what you are testing?
Which variable never changes during the experiment?
This was the theory that living things came from non-living matter. Like mice come from bags of grain or fish come from mud.
All living things are composed of these...the smallest unit of life.
Living things, when it comes to cells, can be either _______ or _______.
This is the process of creating more living things.
reproduction that involves only one parent cell.
reproduction that involves two parent cells
All living things will grow and develop, meaning they have a...
This is a collection of chemical reactions that either produce or use energy.
A tree changing colors, dogs shedding, you changing your wardrobe, bacteria moving away from light...
Response to stimuli
This is the process living things use to maintain a relatively stable internal environment
This is the theory that all living things change over time
This is a set of measurements, based on 10's, that is standard in all areas of science
This is a device that produces a magnified image of an object that is too small to see with the unaided eye.
This microscope will pass a beam of electrons over the surface of a sample to create a 3D image up to 1 million X magnification
scanning electron microscope
This type of microscope uses a electrons to pass through thin sample to create an image up to 1 million X magnification.
transmission electron microscope
The process of living things with favorable traits surviving and reproducing.
Favorable traits in an organism.
This area of biology shows unity...it's all the interactions of diverse living things with each other and their environment.
This is needed to share work with others for review. It also keeps the scientist honest and unbiased.
This is the process of checking your results to see if they are reliable and support your hypothesis (or not).
Analyzing your data!
Cells working together
Groups of tissues with similar functions
A series of organs performing a function
