Water quality, quality sources, CERs
What does ppm stand for?
ppm (parts per million)
Evolution
The change in the heritable characteristics of biological populations over successive generations.
What is the difference between independent and dependent variables?
The independent variable is the "cause" that a researcher manipulates or changes, while the dependent variable is the "effect" that is measured to see if it's impacted by the independent variable.
What is a constellation?
A group of stars forming a recognizable pattern.
8L = ?mL
8L = 8,000 mL
What are settleable solids?
Settleable solids are particles in water or wastewater, like silt, sand, or organic matter, that are heavy enough to sink and settle out of suspension within a specific time (often an hour) using gravity, measured in a container like an Imhoff cone
Cladogram
A cladogram is a diagram that shows the evolutionary relationships among different groups of organisms by illustrating how they diverged from common ancestors.
When do you use a bar graph, scatter plot or a line graph
You use a bar graph when one of the data you are given in non-numerical.
You use a scatter plot to visualize the relationship or correlation between two continuous numerical variables.
You use a line graph to display the change overtime of your variables.
Circumpolar constellations
Constellations that are visible from a certain point at night all night long.
160cm = ?mm
160cm = 1,600mm
Natural selection
The process through which populations of living organisms adapt and change within an enviroment.
What is a qualitative observation?
An observation related to somethings appearance or traits.
What is the relationship between predator and prey?
The relationship between predator and prey is a fundamental ecological interaction where one organism, the predator, hunts and consumes another, the prey.
2.20mg = ?g
2.20mg = 0.00220g
A derived character
A trait that arose in the most recent ancestor of a particular lineage and was passed along to its descendants.
What is a quantitative observation?
A observation related to numbers or the amount of something.
What are the differences between Herbivores, carnivores and omnivores?
Herbivores eat only plants, carnivores eat only meat, and omnivores eat both plants and meat.
What are the base units of the Metric System?
Grams-g, meter-m, and liter-L
A keystone species
A species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
What is the definition of parameters, trials, procedure and scale?
Parameters:A parameter is a numerical characteristic or value that describes an entire population or system
Trials: A trial refers to a single, individual experiment, observation, or attempt carried out as part of a larger study or investigation.
Procedure:A procedure refers to the specific, systematic step-by-step methods and protocols that researchers follow to conduct a study and gather data.
What are Producers, primary consumers, secondary consumers, tertiary consumers?
Producers (plants, algae) make their own food; primary consumers (herbivores like rabbits) eat producers; secondary consumers (carnivores/omnivores like snakes) eat primary consumers; and tertiary consumers (top predators like eagles, big fish) eat secondary consumers,.
What do each of the base units measure?
Liter-L = volume
Meter-m = length
Gram-g= weight
