Define biology.
What is the study of life?
The sum-total of all processes in an organism that convert energy and matter from outside sources and use that energy and matter to sustain the organism's life functions.
What is Metabolism?
Define control group.
What is the group in an experiment that experiences no manipulation?
An abrupt and marked change in the DNA of an organism.
What is mutation?
Define inheritance.
What is the process by which physical and biological characteristics are transmitted from the parent/parents to the offspring?
Define cells.
What are the smartest units of an organism considered alive?
A factor that changes in an experiment.
What is a variable?
Define homeostasis.
What is the maintenance of stable internal conditions?
The sum-total of all processes in an organism that break down chemicals to produce energy and simple chemical building blocks.
What is catabolism?
Define unicellular.
What is "single celled"?
Define microorganisms.
What are living creatures too small to be seen with the naked eye?
Organisms that eat only plants.
What are herbivores?
Define independent variable.
What is the variable manipulated by the experimenter?
Organisms that are able to make their own food.
What are autotrophs?
Define multicellular.
What is "many-celled"?
Define inference.
What is logical interpretation based on prior knowledge, experience, or evidence?
Organisms that eat only organisms other than plants.
What are carnivores?
Define receptors.
What are special structures that allow living organisms to sense the conditions of their internal or external environment?
The idea that long ago, very simple life forms spontaneously appeared through chemical reactions.
What is abiogenesis?
Define photosynthesis.
What is the process by which green plants and some other organisms use the energy of sunlight and simple chemicals to produce their own food?
Define hypothesis.
What is a suggested, testable answer to a well-defined scientific question or a possible, testable explanation for observations?
Organisms that eat both plants and other organisms.
What are omnivores?
Define dependent variable.
What is the variable responding to the manipulated variable?
The sum-total of all processes in an organism that use energy and simple chemical building blocks to produce large chemicals and structures necessary.
What is anabolism?
Define heterotrophs.
What are organisms that depend on other organisms for food?
