Basics Of Biology Flashcards
Biology is…
The study of life
Steps of the scientific method…
Observe Question Make a testable explanation Collect and analyze data State results
Quantitative vs. qualitative data…
Quantity- numerical
Quality- descriptive
Bioengineering…
Application of engineering to medicine
Independent variable vs. dependent variable
Independent- what the scientist controls
Dependent- the results
Control…
Does not receive any changes; test group
Ecology is…
The study of interactions between an organism and its environment
A community is…
How populations of different species in a particular place and habitat interact
Ecosystem ecology is…
The study of communities and their interaction with the physical environment
Abiotic vs biotic factors…
Living
non-living
Population density is…
The ability of a population to grow under ideal environmental conditions
Producers are…
Photosynthesizing organisms
Provides oxygen food and chemical energy in an ecosystem
Birth light parentheses (kinetic) energy to food (chemical) energy
Mutualism, commensalism, parasitism…
Both benefit
One benefits and the other is unharmed
One benefits and the other is harmed
Consumers are…
Any organism that cannot make its own food
Primary, secondary, tertiary Herbivores, Carnivores, omnivores
Carrying Capacity is…
The highest number of a population that the environment can support
A “J” shaped growth curve indicates…
Exponential growth, that has not hit its carrying capacity
The “S” shaped growth curve indicates…
Logistic growth shows a population has reached a balance
Transpiration is…
Plant water loss due to evaporation from leaves
Net Primary Productivity is…
The rate at which plants produce usable food
Hoover Dam influenced fish species along the Colorado river by…
Disturbed the flow of the Colorado river changing temperatures of the river and native to nonnative species
