Unit 1
Most of the teachers dressed up for spirit week.
Is this is example of a qualitative observation, quantitative observation or inference?
Qualitative observation
Provide an example of a specialist species.
Panda bear, Koala bear, tiger salamanders
What is a neutral pH?
7
Wind blows sand from the beach onto the road. This is an example of
Erosion
This is the second most abundant gas in the atmosphere.
Oxygen
All organic compounds contain...
Carbon
When one species benefits and the other is neither helped nor harmed, it is known as...
(example: a remora fish hitches a ride on a whale or shark)
Commensalism
You test water from your local well. You find that it has a pH of 4.2 and a phosphate level of 100ppm. What are two possible pollutants for these results?
Nutrient pollution (such as detergents or agricultural runoff) and acid rain.
This type of rock is formed by the melting and cooling of magma or lava.
Igneous
The country that emits the most carbon dioxide overall.
China
This type of resource that is available in limited supplies and cannot be replenished on human time scales.
Nonrenewable
This type of species acts as a biological smoke alarm for an ecosystem.
Indicator species
Draw the water cycle and label it appropriately.
Condensation --> precipitation --> runoff --> collection --> evaporation/transpiration
When a mineral breaks and has smooth, flat edges, it is known to have
cleavage
What is the correct order of the layers of the atmosphere?
Define tragedy of the commons.
using too much of a shared common resource
Define carrying capacity.
The maximum population size that a particular habitat can sustain.
List the 4 steps of the water treatment process in order.
1. Coagulation and Flocculation
2. Sedimentation
3. Filtration
4. Disinfection
~3
Draw a convention cycle. Explain why certain temperatures are air are sinking/rising.
Warm air is less dense, so it rises.
Cool air is more dense, so it sinks.
How much energy is transferred from one trophic level to the next? What happens to the other energy that is not transferred?
10% is transferred to the next level. The other 90% is lost as heat.
This type of graph is seen when populations initially have rapid growth, but the growth eventually slows.
Logistic
Explain the difference between point and nonpoint pollution.
Point pollution - comes from a specific source. Examples: sewage pipe, factory discharge, oil spill
Nonpoint pollution - comes from many sources. Examples: agricultural runoff, parking lot runoff
ore
What are three evidences of climate change? Who is causing this to happen?
Increased average temperatures, sea levels are rising, extreme weather events, ocean acidification, rivers drying up, animals going extinct, wildfired, etc.
