What is the main function of the nervous system?
To transfer signals throughout the body and allow you to send and receive messages through the body
What is the main function of the muscular system?
To allow movement in the body and its parts
What force keeps us on the ground
Gravity
True or false. Friction does NOT exist.
FALSE!!!!!!
Which ecosystem has the scarcest amount of water
Desert
What is the main organ in the nervous system?
The brain
What are the main systems the muscular system works with
Nervous and skeletal system
what is friction?
When 2 objects rub against each other and it can also slow it down or stop it.
What is the temperature of freezing water
32 degrees Fahrenheit
what is an ecosystem?
An ecosystem is a community of living organisms interacting with the environment, working as a unit. It includes both living factors like plants and animals, and non living factors
What connects the brain to the rest of your body?

What are the cells that transfer signals throughout the body?
Nerves
what are the 3 major types of muscles?
Smooth,cardiac and skeletal muscles
What is force?
A force is a push or pull that can cause an object to move or change its motion.
is heat always moving?
Yes. the particles have kinetic energy which causes them to be constantly moving
What are producers?
Producers are living factors that make their own food.
What is the connection between the nervous system and muscular system?
The nervous system controls the muscular system, transmitting signals from the brain and spinal cord to muscles, making them to contract and relax, and also enables movement.
How does the muscular system work with the nervous system
By allowing movement. Since the muscles are attached to the bones they pull on the bones to make movement.
What is the relationship between force and mass
More force is needed to change the motion of an object with more mass.
What are the 3 methods of heat transfer
conduction, convection and radiation
Carrot-Rabbit-Coyotes-Mountain lion. What would happen to the food chain if the population of rabbits suddenly disappeared
The coyote population would slowly decrease because of the amount of food going missing and if the amount of coyotes goes down so will the mountain lion population since they wont have much to eat. And there would be more carrots since Rabbit wouldn't eat them anymore.
