The action or process of observing something or someone carefully or in order to gain information
What is Observation.

The study of organisms, their environments, and how they interact with each other.
What is Ecology.

Double helix,It has two strands bonded together then twisted in a helical shape,“twisted ladder”.
What is DNA (Deoxyribonucleic acid).
100
Devised an apparatus and process by which life molecules such as amino acids and sugars could be produced from ammonia, methane, hydrogen, and water vapor when electricity simulating lightning was introduced.
What is Miller and Urey.
200
Constant maintenance of an organism's internal conditions.
What is Homeostasis.
200
Complex network of feeding relationships between various organisms in an ecosystem.
What is Food Web.
200
Have specialized flagella for propulsion; contain lots of mitochondria for energy production for movement
What is Sperm Cells.
200
He was credited with the base-pairing rule; bases pair in a ratio of 1:1 to their complimentary base,Adenine always pairs with thymine: A-T or T-A and Cytosine always pairs with guanine: C-G or G-C
What is Chargaff.
200
One of the first scientist to recognize organisms have changed over time.Stated that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime.
What is Lamarck’s Evolution Hypothesis.
300
The study of life.
What is Biology.
300
A density dependent factor. Individuals competing for limited food source or other resources.
What is Competition.
300
Loss of pressure within a cell causing it to shrivel
What is Plasmolysis.
300
Chemical energy (ATP) is converted into glucose. No light required. Uses CO2, produces C6H12O6.
What is Light-Independent Reactions/Calvin Cycle.
300
"Survival of the Fittest.” It said that the “fittest” shall more often than the unfit
What is Natural Selection.
400
A "proposed explanation" of observed phenomena which can be tested for accuracy.
What is Hypothesis.
400
Layer of O^3(3 oxygen atoms attached to each other) that helps protect the Earth and everything on it from the sun's harmful ultraviolet radiation.
What is Ozone Layer.
400
Folded membrane system surrounding nucleus; stores and transmits lipids and proteins throughout cell
What is Endoplasmic Reticulum.
400
The breaking down glucose to form ATP.Occurs in the mitochondria -Folds INCREASE SURFACE AREA!
What is Cellular Respiration.
400
Similar structures (often with completely different functions)
with the same evolutionary origin.
What is Homologous Structures.
500
Summarizes a hypothesis or group of hypotheses that have been supported with repeated testing. If enough evidence accumulates to support a hypothesis
What is Theory.
500
A dramatic change in birth and death rates.
What is Demographic Transition.
500
The concentration of solutes is less outside the cell than inside the cell
What is Hypotonic Solution.
500
Provides small amounts of ATP until the cell can once again obtain enough oxygen to begin the aerobic stages of respiration. **does not last long**
What is Fermentation.
500
When natural selection favors one extreme phenotype of a trait.
