Motion of an object occurs with this type of net force.
What is an unbalanced force?

This states that:

- All living things are composed of cells.

- Cells are the basic unit of structure and function of living thing.

- New cells arise from existing cells.

What is Cell Theory?

A frog and a fly represent this type of relationship.
What is predator and prey? (The frog is the predator that eats the prey, the fly)

A researcher is experimenting how different types of light affect the growth of a plant. They used sugar snap peas, in 500 ml plastic pots of various colors, and soaked each plant for 10 minutes in 75 ml of water every other day. In this experiment, the independent/manipulated variable is _____
What is the type of light? (just saying "light" will not be accepted)
200
Fossil fuels (coal, oil and natural gas) release carbon dioxide into the atmosphere when burned because they are formed from the remains of ancient plants and animals that have undergone this type of change due to heat and pressure over millions of years.
What is a chemical change?
200
This organelle is found in plant and animal cells. It released energy from glucose through a process called cellular respiration, which is why they is often called the "powerhouse of the cell."
What are mitochondria?
200
The source for nearly all the energy in an ecosystem.
What is the sun!
200
The eight planets of our solar system in order from closest to the sun to furthest from our sun.
What is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune?
300
It is important that scientists communicate their results. It allows for ____________, the process of other scientists completing the same experiment in order to verify the original results.
What is replication?
300
Water has a density of 1.00 g/ml. An mystery object has a volume of 10 ml and a mass of 20 g. This object will do this when placed in the water.
What is sink? (20g/10ml = 2 g/ml 2 g/ml > 1 g/ml, therefore it has greater density than water and sinks)
300
Chloroplasts perform the chemical change called photosynthesis using energy from the sun to create glucose (sugar) and oxygen from these two (2) reactants.
What is carbon dioxide (CO2) and water (H2O)?
300
The base of all energy pyramids.
What are producers?
300
The layer of the atmosphere with the highest air pressure. It is where weather happens and we live.
What is the troposphere?
400

Sometimes one or two data points will not fit with the general patterns of the rest of the data set. When viewed on a graph, these anomalies are called outliers, but when viewed in a data table they are called this.

What is anomalous data?

400
125 m/s east, 32 km/hr to the library, 47 cm/min up the plant are all examples of this type of measurement.
What is velocity?
400
This is the process of cellular division that is responsible for growth, healing and development.
What is mitosis?
400
In a food chain/web, the transfer of energy from one organism to another is represented by this.
What is an arrow?

These small rocky bodies are known by three names depending on where they are. In outer space, they go by this name. When they are burning in our atmosphere they are called "shooting stars" or this. Once they land on Earth, they are called this. (You must have all three names in the correct order)
What is meteoriod, meteor, meteorite?

Victor runs 1 km in 3.25 minutes. His time in seconds is ____.
What is 195 seconds?
500
You get thrown around on a roller coaster due to this property of matter, which is often used as a synonym for Newton's First Law of Motion
What is inertia?
500
Material can get into and out of a cell through in two ways: using protein channels, which act as doors to the cell, or directly through the the semipermeable cell membrane. Active transport uses energy to move things in or out of the cell against the concentration gradient; but these two types of passive transport (no energy needed) move things like oxygen, carbon dioxide, and water in and out of the cell along the concentration gradient (from areas of high concentration to low concentration).
What is osmosis (for water) and diffusion (for all other materials).
500
Nitrogen is one of the four most common elements in living organisms. Our atmosphere is 78% nitrogen gas, but very few living organisms can use nitrogen in this form. Some fungi and bacteria "fix" nitrogen from the air into a usable compound for plants. This then cycles through the food chain and decomposers break down the nitrogen in dead things and return it to the soil in usable compounds. This critical cycle for life is called _____.
What is The Nitrogen Cycle?
500
The following things from the list below have more gravity than Earth: - asteroids - Jupiter - stars - Mars - meteors - Sun - Moon - Neptune - Venus - Uranus
What are Jupiter, stars, Sun (which is a medium-sized star), Neptune, Uranus? (This things are all bigger - more massive - than Earth, so they have more gravity)
