What is the term that describes an educated guess of the answer to a problem?
100
This type of bonding occurs when oxygen atoms share electrons.
What are covalent bonds?
100
The two main types of cells.
What are prokaryotes and eukaryotes?
100
The most likely result of damage to the thylakoid membranes in a plant.
What is a decrease in glucose production?
100
Solar energy, wind energy, biofuel, hydropower, and geothermal energy are examples of this.
What are types of renewable resources?

A student is looking to see how much life exists in a pond. They record that 20 amoeba were found in a sample of water. The student is doing what?
What is collecting data?
200
This type of bonding occurs when one atom gives up an electron and another one takes on the electron and they are attracted to each other.
What is an ionic bond?
200
This vascular tissue in plants provides a two-way flow of carbohydrates (food) and water.
What is the phloem?
200
This is the name used to describe an organism that makes their own food through photosynthesis.
What is an autotroph?
200
Coal, oil, and natural gas are examples.
What are nonrenewable resources?
300
Science asks ________ questions about the natural world.
What is testable?
300
The biological macromolecule that provides the quickest energy for an animal to sprint.
What is carbohydrate?
300
This vascular tissue transfers water from the roots through the rest of the plant.
What is the xylem?
300
This is the main role of the electron transport chain in cellular respiration.
What is to make ATP?
300
Starting a recycling program or decreasing consumption are ways to do this.
What are ways to promote more sustainable use of resources?
400
Plankton --> shrimp --> mackerel --> tuna
This will happen if the tuna are killed off by humans.
What is an increase in the mackerel population?
400
Making muscle tissue, transporting other molecules in the body and moving material in and out of the cell are all functions of this macromolecule.
What is a protein?
400
This feature of a cell membrane prevents water from entering the cell.
What is the nonpolar lipid layer?
or nonpolar fatty acids?
or phospholipids?

The type of relationship that occurs when one organism benefits and the other organism is harmed.
What is parasitism?
400
This is the most likely outcome of increased global temperatures.
What is rising sea levels?

Chipmunks sleeping underground through the winter, birds moving south when the weather gets colder, or frogs digging into the mud to hibernate in the winter are examples of this.
What are results of seasonal change?

This is an example of (saturated/unsaturated) fat.
What is a saturated fat?
500
This type of cellular transport uses a protein to move a molecule across a cell membrane without energy.
What is facilitated diffusion?
500
This part of cellular respiration must occur before any of the other steps can occur.
What is glycolysis?
500
These organisms fix nitrogen gas into usable forms for plants.
What are bacteria?
