Define Invasive Species. What is an example?
Invasive Species: an introduced, nonnative organism (disease, parasite, plant, or animal) that begins to spread or expand its range from the site of its original introduction and that has the potential to cause harm to the environment, the economy, or to human health.

Anthrax
Lyme disease
Malaria
Smallpox
Lyme Disease
Often, some sort of physical barrier (for example, a new mountain range, canyon, or islands) will separate populations of a species, which will adapt to the new environments through natural selection and, over time, become distinct species. What is the term called to describe this process?
Coevolution
Speciation
Mutation
Population Density
speciation
A biome is a very large area of the Earth’s surface defined by climate. Climate includes which two abiotic factors?
1. Temperature and Precipitation
2. Temperature and Wind
3. Wind and Precipitation
4. Elevation and Available Food
2. Temperature and Wind
What are the products of photosynthesis?
Glucose and Oxygen
Which part of the respiratory system is also a common passageway for the digestive system?
pharynx
A new disease has suddenly appeared and scientists are trying to determine whether the disease agent is a virus or a bacterium. They collect the following information:
The disease can be transmitted through the air.
The disease agent is too small to be seen under a light microscope.
There are no known antibiotics that are effective against the disease.
The genetic material of the disease agent is DNA within a capsid.
The disease agent cannot be cultured using any known culture medium.
Is the above disease agent most likely a bacterium or a virus?
The disease is most likely a virus.
This is because bacteria can be removed using antibodies while viruses cannot. Also, viruses contain DNA in its capsid. Another thing is that viruses can only be seen using an electron microscope.
The island of Daphne Major was an ideal study site because the finches had little competition (the only other finch on the island is the cactus finch) and few predators. Therefore, the selective pressure controlling the survival of the medium ground finch are ______________________ and ______________________.
Weather & Subsequent Availability of Food
Disease & Large Ground Finches
Pathogens & High Temperature
Geographic Access & Predators
Weather & Subsequent Availability of Food
