The three types of biodiversity are

• genetic, species and ecosystem
• medical, agricultural, ethical
• habitat loss, pollution, overharvesting
• camera traps, invasive species, cookies

What is power 

• energy of motion 
• The rate at which work is done
• radioactive decay
• Potential energy

The bond formed when elements share electrons 

• Covalent bonds 
• ionic bond
• Hydrogen bond 
• polar bond 

The concept of ecological footprint is measured in terms of the amount of:

• resources an individual consumes daily
• land area
• resources an individual consumes over the course of a lifetime
• resources an entire nation consumes yearly

According to the law of conservation of matter,
I. matter can be created
II. matter cannot be destroyed
III. after a chemical reaction, the original atoms remain

• I onlt
• II only
• III only
• II and III

A negative feedback loop is:

• when feedback into the system increases the rate of progress
• seen in the example of increased greenhouse gases leading to global warming
• seen in the example o world population growth
• when a system responds to a change by returning it to its original state

Using the graph, what conclusion can be drawn about the relationship between temperature and the saturation point of air?

• As temperature increases, saturation point decreases exponentially
• As temperature increases, saturation point increases exponentially
• As temperature increases, saturation point decreases linearly
• As temperature increases, saturation point increases linearly

One example of the tragedy of the commons can occur when several farmers share the same pasture for feeding sheep.  The root cause of this tragedy is that:

• people are inherently bad.
• sheep reproduce too quickly
• the market cannot support too many farmers
• the farmers believe that if they don't use it, someone else will

Studies that last for only 1 to 4 days in which scientists measure mortality of organisms as a response to a dose of a chemical are known as

• acute studies
• biomagnification studies
• prospective studies
• chronic studies

Exchanges of energy always yield useless energy

• Kinetic energy
• First Law of Thermodynamics
• Second Law of Thermodynamics
• Conservation of mass
