2 Questions and Answers
The development of new varieties of grain crops increased productivity by
increasing the: - ANSWER- size and number of seeds
The most effective way to reduce the GHG emissions is to increase: -
ANSWER- energy efficiency and renewable energy
A farmer is tired of watching crops die in the field from several pest
species. She decides that next year she is going to use every type of
ecological pest control she can find to address the problem. Over the winter
she gets ready, ordering pheromones that interfere with reproduction of the
pests, sterile male flies that will try to reproduce with some of the pest flies,
and wasps that lay their eggs in the larvae of another pest. It is expensive,
but she thinks this should work well. Which of the following forms of
control is she not using? - ANSWER- Cultural control
Sustainable agriculture in the long term will require: - ANSWER-
decreasing the use of fossil fuels and synthetic fertilizers.
Global warming is raising sea levels because of: - ANSWER- melting ice
and thermal expansion.
Food safety issues of transgenic crops include: - ANSWER- the promotion
of antibiotic resistance in pathogens and new allergic properties in crops.
Climatologists warn of a tipping point when global temperatures trigger
unavoidable catastrophic events and sea levels rise more than 25 feet. What
single event would cause the sea level to rise that much? - ANSWER-
Melting of the Greenland Ice Sheet
One ongoing concern about transgenic crops that produce pesticides is that
this trait may: - ANSWER- kill other insects that are not pests.
If the Earth had no atmosphere: - ANSWER- The biogeochemical cycles
and climate on Earth would be much different.
,Herbicides would be most useful in combating: - ANSWER- Weeds that
infect our agricultural fields.
War is most likely to contribute to famine: - ANSWER- Where poverty,
food production, and distribution are already problematic.
Permanent polyculture is an approach to sustainable agriculture where
farms: - ANSWER- And the crops grown on them are modeled on natural
ecosystems.
All of the following affect the global rise in food prices, except: -
ANSWER- A marked decline in demand for meat and animal products,
especially in China and the United States.
For more than 20 years, scientists have been analyzing expected climate
change and the impact on crops grown in particular regions. For example,
states that typically plant corn and soybeans may need to switch to growing
cotton. Such a change is an example of: - ANSWER- Adaptation
People most concerned about the side effects of bioengineering would more
likely accept: - ANSWER- Crops produced by conventional plant breeding
methods or by marker-assisted breeding
A promising alternative to toxic pesticides used to reduce the billions of
dollars in damage done by marine biofouling organisms is: - ANSWER-
Polymers that make it difficult for the organisms to attach to a substrate.
As the climate becomes warmer in mountainous regions, the biological
effects on mountain ecosystems will: - ANSWER- probably cause the
extinction of high-altitude species as their habitats warm.
Which one of the following is not an example of geoengineering? - ANSWER-
Erecting large fields of wind turbines to generate electricity to power
automobiles
In the United States, global climate change skeptics and deniers are largely
sorted: - ANSWER- Along political lines
, Deliberate campaigns of misinformation with the intent to create mistrust in
climate science have been vigorously pushed by: - ANSWER- Organizations
and corporations (such as oil companies) who stand to lose profits if fossil fuel
use is reduced
The sharp decrease in atmospheric 14C (Carbon-14) in the past decade is
directly related to: - ANSWER- Increased use of in fossil fuels
The Industrial Revolution resulted in many changes to farms in the United
States, and it: - ANSWER- Increased the efficiency of farming resulting in
fewer, but larger farms.
The inside of a car (or greenhouse) heats up in the presence of sunshine
because: - ANSWER- The energy from infrared radiation is trapped in the car.
The most dramatic temperature shifts in the past few decades have been: -
ANSWER- in the north and south polar regions.
Discussing the consequences of global climate change at a conference,
representatives of a developing nation suggest that those nations that contribute
the most greenhouse gases (GHGs) to the atmosphere should contribute the
most to paying for adaptive responses worldwide. Further, this representative
pointed out that her poor country contributes less than 1% of the annual GHGs
and has less than 0.1% of the world's wealth. This representative's appeal
represents: - ANSWER- The polluter pays and equity principles.
You discover a sealed plastic bag of rice is teeming with tiny insects. You have
probably found an infestation of: - ANSWER- stored product pests that can live
with almost no water and are resistant to pesticides.
Most of the weather of the world is based upon changes in moisture, pressure,
and/or temperature of the: - ANSWER- troposphere.
