Living Things, Organisms, & Ecosystems
This is the smallest unit of life that can carry out all basic life functions.
a cell
This is the energy an object has because of its motion.
Kinetic Energy
This type of energy is when there are electrons moving
Matter that has a definite shape and volume, with particles packed tightly together, is in this state is known as what state of matter?
A solid
This is the thin, outermost layer of Earth where we live.
The crust
This scientific idea states that all living things are made of cells, cells come from pre-existing cells, and cells are the basic unit of life. What is this Theory called?
What is the cell theory?
This type of energy is stored energy, such as energy in a stretched rubber band or an object held above the ground.
Potential Energy
When you push a book across a table, your push is this type of force, while the table pushing up on the book is this type of force.
Normal/applied force
Which of the following is the best example of a pure substance?
a.) salt b.) Oxygen c.) atmospheric air d.) water
b.) Oxygen
This thick layer beneath the crust is made of slowly moving rock and helps drive plate movement.
The Mantle
A group of the same species living in the same area is called this, which is one level in the organization of ecosystems called?
Is a population
When energy changes from one form to another, like chemical energy in food turning into motion, this process is called this.
What is the unit of measure when using force?
Newtons
This property compares how much mass is in a given volume and helps determine if an object will float or sink.
Density
The movement of these large pieces of Earth’s crust can cause earthquakes, volcanoes, and mountains to form.
Tectonic Plates
When organisms fight over limited resources like food, water, or space in an ecosystem, this interaction is taking place. This is called what?
Competition
Explain the definition of: Law of Conservation of Energy
This law states that energy cannot be created or destroyed, only transferred or transformed.
If a box has 10 N of force pushing right and 6 N pushing left, the total force acting on the box is this.
What is the final force and direction?
4 N to the right
Bubbles forming, a color change, or a new smell are all signs that this type of change has occurred.
Chemical Change
Resources like sunlight and wind that can be replaced naturally over time are classified as this type of resource.
Renewable resources
This type of symbiotic relationship benefits one organism while harming the other, such as a tick feeding on a dog.
Parasitism
In this type of wave, particles move parallel to the direction the wave travels, like in a sound wave, showing how energy is transferred.
Longitudinal Waves
Name 4 types of different forces?
Applied, frictional, gravity, magnetic, normal, and tension.
Object A has a density of 2 g/mL and Object B has a density of 0.8 g/mL. When placed in water, this will happen to both objects.
What will happen to Object A and what will happen to Object B?
Object A will sink
Object B will float
Reducing fossil fuel use, recycling materials, and conserving water are all examples of actions that help achieve this goal related to Earth’s resources and human impact is called what?
Conservation of natural resources
