Which of the following is a basic characteristic of bacteria that distinguishes them from viruses?
Bacteria can reproduce on their own, while viruses need a host cell.
Bacteria are always harmful, while viruses are always helpful.
Bacteria are not living organisms, while viruses are living.
Bacteria do not have genetic material, while viruses do.
What is the main function of producers in a food web?
Breaking down dead organisms
Making their own food through photosynthesis
Eating other animals for energy
Competing for shelter
Which physical factor is commonly measured to determine the potability of water in North Carolina?
Wind speed
Turbidity
Soil type
Air pressure
What is the largest source of freshwater on Earth?
Oceans
Glaciers and ice caps
Rivers
Underground caves
A student observes that a local pond has become cloudy and fish are dying. Which combination of water quality factors should the student test to help determine the cause?
Temperature, dissolved oxygen, and turbidity
Wind speed, soil pH, and sunlight
Air pressure, humidity, and rainfall
Rock type, soil color, and plant height
A community is experiencing an increase in cases of a disease caused by a parasite. Which prevention method would be most effective in reducing the spread?
Washing hands regularly and cooking food thoroughly
Taking antibiotics for all illnesses
Avoiding all contact with animals
Increasing the use of chemical fertilizers
If a drought reduces the amount of water in a river ecosystem, what is the most likely effect on the populations of fish and aquatic plants?
Both populations will increase due to less competition.
Both populations will decrease due to limited resources.
Only fish populations will increase.
Only plant populations will decrease.
A student is given a diagram showing several rock layers with different fossils. How can the student determine which rock layer is the oldest?
By identifying the layer with the most recent fossils
By finding the bottommost layer in the sequence
By measuring the thickness of each layer
By counting the number of fossils in each layer
A city near the coast of North Carolina notices a sudden drop in dissolved oxygen in its estuary. Using evidence, explain how this could impact both the local ecosystem and human activities, and suggest a strategy for monitoring or improving water quality.
Low dissolved oxygen can cause fish kills, harming the ecosystem and local fishing industry; regular water testing and reducing pollution can help.
Low dissolved oxygen will only affect plant growth, so no action is needed.
High dissolved oxygen is dangerous for humans, so swimming should be banned.
Dissolved oxygen does not affect living organisms, so monitoring is unnecessary.
A new disease spreads rapidly across several continents, causing global concern. Using reasoning, explain how this situation is classified and what strategies could be used to prevent further spread.
It is a pandemic; strategies include international cooperation, vaccination, and public health measures.
It is an epidemic; only local measures are needed.
It is a parasite outbreak; antibiotics are the only solution.
It is a seasonal illness; no action is required.
