time - correct answer ✔✔true
Which of the following is an accurate statement about the current ecological footprint, in terms
of global hectares, of people on Earth?
- Most people around the world have about the same-sized ecological footprint
- Currently, the average ecological footprint is greater than what the Earth can support
- There are enough resources on Earth for everyone to have an ecological footprint the size of
the average U.S citizens.
- The per capita Ecological Footprint can only grow larger with time - correct answer ✔✔-
Currently, the average ecological footprint is greater than what the Earth can support
Environmentalism stemming from the publication of Rachel Carson's Silent Spring differed from
earlier North America conservation perspectives by:
- Focusing on human population growth
- placing more emphasis on pollution problems
- Emphasizing international problems
- Encouraging energy efficiency
- Emphasizing the value of natural resources - correct answer ✔✔placing more emphasis on
pollution problems
Which of the following is not a component of Garret Hardin's notion of the Tragedy of the
Commons?
- population growth invariably leads to the overexploitation and destruction of ecosystem
services.
- People who own resources will protect it out of self interest
, - Strong social connections between those invested in a resource encourage it's conservation
- A legal regulatory framework that uses punishment to discourage exploitation of - correct
answer ✔✔population growth invariably leads to the overexploitation and destruction of
ecosystem services.
which of the following might indicate that a scientific study is pseudoscience?
- It is a double-blind study
- its findings were published in a scientific journal
- It was conducted by a special interest group
- it was well supported by other scientists - correct answer ✔✔it was conducted by a special
interest group
In a system, which of the following encourages homeostasis?
- negative feedback loops
- positive feedback loops
- disturbances
- state shift - correct answer ✔✔negative feedback loops
In statistics, what is the difference between a sample and a population? - correct answer ✔✔A
sample is a subset of a phenomenon, the population is the (usually theoretical) collection of
every single instance of that phenomenon.
During photosynthesis, light energy is converted into chemical energy, which is a type of what
energy - correct answer ✔✔potential energy
The smallest unit of a chemical element that displays the properties of that element is an __ -
correct answer ✔✔atom
