Which organelle controls what enters and leaves the cell?
What is Cell membrane
100
What is a gene?
What is Segments of DNA that code for traits
100
What does biodiversity refer to?
What is The variety of living organisms in an area?
100
Describe two processes that move carbon through the carbon cycle in living things.
What is Plants absorbing CO₂ and animals releasing CO₂?
100
What is the main cause of global wind patterns
What is uneven heating of the earth by the sun.
200
Which organelle is called the “powerhouse of the cell” and what is its main function?
What is mitochondria, it produces the energy for the cell.
200
What is an adaptation?
What is something that helps an organism survive and reproduce in it's environment?
200
Give one major effect of low biodiversity on an ecosystem
What is ecosystems are less sustainable.
200
What removes carbon from the atmosphere?
What is photosynthesis?
200
Warm ocean currents generally cause nearby land to have what kind of temperature change
What is warmer temperatures?
300
Name the structure that stores genetic material and one function it performs.
What is Nucleus; stores DNA and controls activities
300
What is a structural adaptation?
What is the way an organism is built or its particular parts?
300
If pollution kills the grasses in a food web, describe the most likely long-term effect on the entire web and why.
What is There may be a short term decrease in primary consumers, but in a food web there will be multiple producers and the ecosystem will recover.
300
A scientist records CO₂ (ppm): 370 → 390 → 415 from 2000 to 2020. What trend is this, and give the MOST likely human cause
What is CO₂ is increasing; most likely cause: increased fossil fuel use?
300
A weather report shows low air pressure and increasing humidity. What weather conditions are most likely to occur?
What is Likely precipitation/storms (low pressure + humidity encourages rising air and cloud formation)
400
Identify two differences between plant and animal cells.
What is Plant cells have cell walls and chloroplasts and large central vacuole; animal cells lack cell wall and chloroplasts and have smaller vacuoles
400
What is a behavioral adaptation?
What is the way the organism acts?
400
Name the type of succession that will occur here and the first species to arrive.
What is primary succession and lichen and moss?
400
Explain how planting thousands of trees in a city affects the carbon cycle and how that action might affect climate over time
What is Trees absorb CO₂ via photosynthesis and over time this can lower atmospheric CO2
400
Explain how uneven heating from the Sun causes air to move in the atmosphere
What is the sun heats earth's surface unevenly; warm air rises where heated, cool air sinks, creating convection currents and wind from high to low pressure
500
Which organelle makes protiens for the cell?
What is the ribosome?
500
Describe how genetic variation can affect which individuals survive after an environmental change
What is if you don't have the traits to make you successful you will not survive.
500
What type of succession will occur after a forest fire and what is the final stage in succession called?
What is secondary succession and climax community?
500
How do volcanic eruptions affect climate?
What is cause temporary cooling as ash and debris blocks the sun. Long term adds CO2 gasses to the atmosphere.
500
Given ocean surface temperature 82°F (28°C), high humidity, and warm air rising rapidly, which severe weather event is most likely to develop and why?
What is a hurricane may develop — warm ocean surface and high humidity provide energy and rising air needed for cyclone formation
