The sample in an experiment that is unmodified is called the result variance control test

Control

We measure the intensity of sound in decameters decisound decibels mesibels

Decibels

As water warms up, the oxygen holding capacity of water declines increases stays the same is not measurable

Declines

The toxicity of some elements increases as pH increases decreases stays constant is removed

Decreases

Energy Star

The main reason Louisiana is losing much of its coastal wetlands is due to development hunting and fishing erosion volcanic activity

Erosion

False

Time of day makes no difference in the sound meter reading you would obtain on campus True False

False

When measuring turbidty from a bridge far above the water, it is necessary to use the tube rather than the disk True False

False

According to http://www.epa.gov/fueleconomy/ which of these vehicles has the best estimated gas mileage Cadillac CTS Honda Fit Ford F150 Hyundai Santa Fe

Honda Fit

Lentic

Naturally occurring carbonic acid is known to be mildly acidic toxic to humans extremely acidic basic

Mildly acidic

Buffered lakes are more neutral acidic basic none of the above

Neutral

Wetlands help improve the quality of our water as they remove nitrogen and phosphorus oxygen helium neon

Nitrogen and phosphorus

The factor that does NOT affect the cost of enetrgy is demand wars ocean currents oils spills

Ocean currents

A _______ is a number utilized to define a condition or state. scalar result variable design

Scalar

We can indirectly measure turbidity with the use of a hula hoop sechi disk tiddly wink fresci disk

Sechi disk

Plants that grow largely underwater are known as submerged deep rooted floating emergent

Submerged

An area of the wetlands that provides cover from predators is called the levee the edge zone the depths the high flow area

The edge zone

According to http://www.epa.gov/fueleconomy/ which of these vehicles has the worst estimated EPA mileage Toyota Tacoma Toyota Prius Chevrolet Spark Tesla Model S

Toyota Tacoma

A high reading with the turbidity tube means the water has very few suspended materials True False

True

__________ is the measurement of the amount of suspended material in water. Density Viscosity Turbidity Baylocity

Turbidity

If the water is too shallow to use the standard turbidity measuring device, we may use a turbidity tube water stake depth mark tube transect
