list the levels of classification starting with the broadest level
Domain Kingdom Phylum Class Order Family Genus Species
In the organization of living things, tissues combine to form
Organs
What is independent and dependent variable?
factor in the experiment that is change by the experimenter
the measurable outcome that depends on the IV
The measure of the distance an object travels in a certain length of time is the object's
The measure of the distance an object travels in a certain length of time is the object's speed. Speed describes how fast the object is moving.

What is the language used to classify living things
Latin
What is cell theory?
3 main points
After doing research on plants and fertilizers, a 5th grade science class states the hypothesis for their experiment; "If a plant receives fertilizer, then it will grow to be bigger than a plant that does not receive fertilizer."
What is the independent variable and dependent variable?
IV-Fertilizer
DV-plant growth
A boulder that is resting on the top of a cliff slips over the edge and accelerates towards the ground. As the rock falls, the amount of kinetic energy
As the rock falls, the amount of kinetic energy increases. Kinetic energy is energy of motion, and potential energy is transformed to kinetic energy as the rock accelerates toward the ground.
The surface of the Earth changes from processes such as erosion. Give an example of these changes to Earth’s surface due to erosion?
the wind picking up dust and carrying it
Water carrying sediment
movement of sediment
What does the scientific name consist of
written in Latin, it includes the genus name followed by the species name
What name is given to a set of organs that work together to perform a specific function?
system

C)A hypothesis must be testable and theory does not need to be testable.
D)A theory must be testable and hypothesis does not need to be testable.

When a moving object is acted on by unbalanced forces, the object will
A)stop moving.
B)move in unpredictable patterns.
C)move in the same direction as the stronger force.
D)move in the direction opposite the stronger force.
C)move in the same direction as the stronger force.
When air masses collide in the atmosphere, different types of fronts can form. Which type of front forms when a warm air mass gets caught between two cold air masses?
occluded Front
Bacteria, Archaea, and Eukarya
What are two organelles/structures found in a plant cell but
cell wall

B)F = ma; force equals mass times acceleration.
C)For every action, there is an equal and opposite reaction.
D)The Earth’s magnetic field is generated by a conducting fluid in its core.
D)The Earth’s magnetic field is generated by a conducting fluid in its core.
A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing.
Jill activates a reusable hand warmer on a chilly day. As it warms her hands, the liquid inside the warmer crystallizes. Describe the process.
A)Chemical energy is modified to mechanical energy during the crystallization.
B)The energy in the liquid is reformed in an endothermic crystallization reaction.
C)The potential energy of the supersaturated liquid is converted to heat as the compound crystallizes.
D)The kinetic energy in the liquid is transferred to the crystals is an endothermic process.
C)The potential energy of the supersaturated liquid is converted to heat as the compound crystallizes.

Clostridium botulinum is a pathogenic organism that has been shown to be of some benefit as well being potentially dangerous to humans. It was first discovered as one type of food poisioning, but it is now being used by cosmetic surgeons as a way to remove wrinkles.
This organisms is BEST classified as a
bacterium
