Forces and Motion
Which force pulls all objects down towards Earth?
Gravity
All living things are made of this basic unit.
Cells
This organelle controls all cell activities.
Nucleus
This system helps defend the body from disease.
Immune system
This type of organism includes mold and mushrooms. They like humid and dark environments
Fungi
When forces are equal and opposite, the object’s motion does not change.
Balanced Forces
The ability to keep internal conditions stable or balanced.
Homeostasis
These tiny structures build proteins.
Ribosomes
This system carries oxygen and nutrients through blood.
Circulatory system
These are nonliving particles that need a host to reproduce.
Viruses
This law explains why a skateboard moves backward when you push forward. (every action has an equal and opposite reaction)
3rd law
Arrange from smallest to largest: organ, cell, organ system, tissue
cell → tissue → organ → organ system
This organelle makes energy also called the “powerhouse” of the cell.
Mitochondria
This system brings oxygen into the body and gets rid of carbon dioxide
Respiratory
These are living, single-celled organisms that can be both beneficial or negative
Bacteria
This force slows down a sliding object and produces heat.
What is friction?
A group of similar cells working together.
Tissue
This structure in plant cells helps make food using sunlight. (photosynthesis)
Chloroplast
This system is responsible for sending electrical signals throughout the body
Nervous
What can be used to treat bacterial infections?
Antibiotics
Which law says
"An object at rest stays at rest, and an object in motion stays in motion unless acted on by a force."
Newton's 1st law
Name all 3 parts of cell theory
1. All living things are made of one or more cells
2. Cells are the basic unit of life
3. All cells come from preexisting cells
This structure protects plant cells and gives them shape, but is not in animal cells.
Cell wall
This system is responsible for producing and sending out hormones
Endocrine
What pathogen is both unicellular and prokaryotic?
Protist
