Characteristics of living things
The study of living things.
What is biology?
The first step toward scientific discovery.
What is observation?
Grams would be used to measure an objects what?
What is mass?
The scientific study of interactions among organisms and their environments.
What is ecology?
Organisms that use energy from the sun or energy stored in chemical compounds to manufacture their own nutrients.
What are autotrophs?
Any structure, behavior, or internal process that enables an organism to respond to stimuli and better survive in an environment.
What is an adaptation.
A testable statement or question to answer.
What is a hypothesis?
What is 2.54?
Levels of organization in ecology:
What are:
Biosphere, Ecosystems, communities, populations, and organism.
Organisms that cannot make their own food and must feed on other organisms.
What are consumers or heterotrophs?
Regulation of an organism's internal environment to maintain conditions suitable for its survival.
What is homeostasis?
The experimental group in which all conditions are kept the same except for the single condition being tested:
What is the control?
This unit would be used to measure bacterial growth on a petri dish.
What is millimeters?
The role and position a species has in its environment-how it meets its needs for food and shelter, how it survives and how it reproduces.
What is a niche?
Some organisms, such as fungi, break down and absorb nutrients from dead organisms.
What are decomposers?
The production of offspring.
What is reproduction?
The condition in an experiment that is changed.
What is the independent variable?
The human body temperature in degrees C.
What is 37 degrees Celsius.
A symbiotic relationship in which one species benefits and the other species is neither harmed nor benefited.
What is commensalism?
This percentage of energy is passed from one trophic level to the next.
What is 10%?
All living things are composed of one or more cells. Each cell contains this genetic material:
What is DNA?
While changing the independent variable, the scientist observes or measures a second condition that results from the change.
What is the dependent variable?
57 meters in millimeters.
What is 57,000 millimeters?
A symbiotic relationship in which both species benefit.
What is mutualism?
Autotrophs use photosynthesis in the formation of energy using raw energy from the sun, carbon, and water. When heterotrophs feed on autotrophs, they reverse this process releasing carbon back into the atmostphere.
What is cellular respiration?
