TRUE or FALSE
You can view a live specimen when using the Transmission Electron Microscope (TEM)
FALSE! Because you are using a beam of electrons the specimen cannot be alive.

TRUE or FALSE
The use of renewable resources do not cause environmental harm.
FALSE! Clearing of land for solar farms or wind turbines can destroy entire ecosystems.

__________ is when water bonds to other molecules and _________ is when water molecules bonds to other water molecules.
ADHESION is when water bonds to other molecules and COHESION is when water molecules bonds to other water molecules.
200
One positive and one negative for use of renewable resources.
Positive- Clean energy- no CO2 emissions; sustainable
Negative- High cost; destroy ecosystems due to land clearing

What determines the carrying capacity of a population?
Limiting factors/available resources

A tree falls in a forest and begins to decay. Over time, fungi and bacteria break down the tree's tissues, releasing carbon dioxide into the atmosphere.
Which process is directly responsible for the release of carbon dioxide in this scenario?
Decomposition

If biodiversity decreases within an ecosystem, what will happen to the ecosystem?
The ecosystem will become UNSTABLE and WEAKEN or COLLAPSE.
300
What are TWO differences between the Compound Microscope and the Transmission Electron Microscope (TEM)?
Compound- uses light, live specimen, 1000x magnification
TEM- uses electrons, dead specimen, 50,000x magnification

When carbon dioxide is taken in by the oceans through the process of diffusion, which property of water supports this?
Universal Solvent

A grasshopper obtains 1,000 units of energy by eating plants. Only about 100 units become available to the frog that eats the grasshopper.
Why is it that most of the energy is not transferred to the frog?
The energy is either lost to the environment as heat or used by the grasshopper in metabolism

___________ is when the oceans constantly take in AND release carbon dioxide (CO2) with the atmosphere
Diffusion

In a meadow ecosystem, rabbits feed on grasses and are an important food source for foxes. A disease causes the rabbit population to decrease significantly. Which outcome is most likely?
A. The grass population increases because fewer rabbits are eating it.
B. The fox population increases because fewer rabbits compete for food.
C. The grass population decreases because less energy enters the ecosystem.
D. The fox population immediately increases because more energy becomes availa
A. The grass population increases because fewer rabbits are eating it.

During a biology lab, a student collects a sample of pond water and places a drop on a glass slide. The student wants to observe living microorganisms in the water and compare their size and shape. The student needs to magnify the organisms while allowing light to pass through the sample. Which microscope should the student use?
Compound Light Microscope
500
In northern lakes, the surface water freezes during the winter months creating an insulated barrier to keep the water below slightly warmer allowing life to survive. Which water property allows this?
Expansion upon freezing

Which of the following best describes a benefit of non-renewable energy use?
A. Scientific advances now allow us to synthesize fossil fuels, making them renewable.
B. Ecosystems will be healthier as dangerous chemicals in fossil fuels are extracted for use as energy.
C. Removing these energy sources will stabilize the abiotic factors in the ecosystem, making them more resilient to change
D. The infrastructure to distribute and use this energy is already in place, therefore fewer surrounding environments need to be disturbed.
