Vocabulary 1
Nerve cells that transfer information in the form of electrical energy to the brain
Neurons
Receptors that detect chemical signals, such as odors and tastes
Chemical

Roots
Which level of organization best describes the brain and stomach?
Organ
The process of regulating body temperature is an example of what type of feedback in homeostasis?
Negative
Specialized structures in the nervous system that respond to specific types of stimuli, or environmental messages
Sensory receptors
Stored information in the brain
Memory
What is the plant organ responsible for absorbing light energy to make food?
Leaf
The esophagus, stomach, and colon work together to perform what function?
Digest the food we eat (digestion)
(1) What does the term structure refer to? (2) What does the term function refer to?
Structure is what something looks like or what it is made of. Function is the job that something performs.

Behavior that depends on memory and experience
Learned
Animals breathe in oxygen and exhale carbon dioxide. Where does the oxygen come from?
It is released during photosyntheis.
What comes next:
cardiac muscle cell --> cardiac tissue --> heart --> ?
Circulatory system
Give an example of an innate behavior.
Set of actions taken by an organism in response to stimuli
Behavior

Mechanical
What is the source of the energy that plant cells use for photosynthesis?
Radiant energy (sunlight)
What two systems work together to keep carbon dioxide levels low in the body?
A plant leaf is an organ. In what way is a human lung similar to a plant leaf?
They both exchange gases (carbon dioxide and oxygen).
Bodily process that maintains stable conditions in a changing environment
Homeostasis
Behavior that does not require learning or experience
Innate

How are memory and behavior related?
An organism's memories influence its behavior.
