Order the steps of the viral cycle
1. Entry
2. Uncoating
3. Genome Replication
4. Synthesis
5. Assembly
6. Release
Symptoms of a viral infection occur at this step in the cycle
Release
The ribosomes of the host cells produce viral proteins at this step
Synthesis
The capsid of an invading virion breaks down at this step
Uncoating
Virion components come together spontaneously during this step
Assembly
The viral genome takes over host cell function at this step
Genome Replication
Endocytosis might be a mechanism used in this step
Entry
The first virus discovered was a(n):
Helical virus
What is an arbovirus?
An arthropod-borne virus
Which one of these is considered the most contagious disease in the world?
Rotavirus
Which one of these diseases is caused by an arbovirus?
Zika

Prions
Prions usually affect which organ?
Brain
The first prion-caused disease ever described was...
Kuru
Most viruses that have human hosts:
Are enveloped viruses
Which one of the following statements is true about the viral genome?
Their genome might consist of DNA or RNA
An example of an arbovirus other than West Nile virus or Zika is...
Yellow Fever
Emphasizes energy flow and chemical cycling among the various biotic and abiotic components.
Ecosystem
Studies how an organism's structure or physiology meet environmental challenges.
Organismal
A mosaic of connected ecosystems
Landscape
Examines the effect of intraspecific interactions / competition
Population
Examines the influence of energy and materials on organisms across the biosphere
Global
Exchanges of energy, materials, and organisms across multiple ecosystems
Landscape
Interactions at the global scale
Global
Examines the effects of interspecific interactions / competition
Community
Focuses on factors affecting population size over time
Population
If you study how nitrogen is transferred from one species to another in a lake, you are a(n):
Ecosystem ecologist (interaction of the community with physical factors)
A scientist is examining how fast a colony of pathogenic bacteria grows on a culture plate when it's been given certain nutrients. This scientist could best be described as a(n):
Population ecologist (same species being examined)
A scientist who studies the interactions of introduces probiotics with the other bacteria living in the human intestinal tract is a(n):
Community ecologist (different populations of bacteria studied)
A meteorologist is using a computer model to determine the effects of an El Nino event on the Southern Hemisphere on the weather in North America. What type of ecologist is this?
Global ecologist
What is albedo? Where on the Earth do we get low albedo?
Light reflected versus light absorbed (low albedo: equator) (high albedo: poles)
What are the four factors that affect population size over time?
Birth, Death, Immigration, Emigrantion
At this moment, you are closet to which of the following latitudes?
30 degrees North latitude
Depending on its range, the diet of a population of black bears might be predominantly animal materials or it might be predominantly plant materials. There is a scientist who is studying how a mostly-animal and a mostly-animal and a mostly-plant diet differentially influence the development of bear cubs. Such a scientist would best be described as a(n):
Organismal ecologist
Which of the following conditions existed exactly one week ago?
Both the North Pole and the South Pole pointed towards the sun
What are the three types of spatial distributions? Describe each
Clumped (most common)
Uniformed
Random (least common)
Populations that exhibit a wide niche breadth are referred to as _ species while those that exhibit a narrow niche breadth are referred to as _ species.
generalist; specialist
Dispersion pattern of plants whose seeds are wind-carried
Random
Dispersion pattern of a territorial bird species living in a forest of same-sized trees
Uniform
Dispersion pattern of plants such as bamboo that grow connected together
Clumped
Dispersion pattern used to maximize crop yields in agricultural fields
Uniform
The least common dispersion pattern in nature
Random
