How does the skin help regulate body temperature? by enabling excess heat to escape from the body.
Beneath the outer membrane of bone there is a layer of compact bone
Which is NOT a function of the cardiovascular system? controlling many body processes by means of chemicals
blood vessels that carry blood away from the heart are called arteries
In which vessels are materials exchanged between the blood and body cells? capillaries

Gases pass in and out of a leaf through the stomata
What is not a root function in plants? to produce food.
Which substances are produced during respiration? carbon dioxide and water
Where in the respiratory system does gas exchange occur? in the alveoli.
The role of the respiratory system is to bring what substance into the body? oxygen
The dome-shaped muscle that plays an important role in breathing is the diaphragm.
What is the main function of the excretory system? to collect and remove wastes from the body.
Which excretory organ eliminates water and some chemical wastes in perspiration? skin.
what term do scientists use to describe the chemical process in which oxygen and glucose react to realease energy inside body cells? respiration
Each alveolus is surrounded by a network of capillaries
When the nervous system makes you feel hungry or thirsty, what body process is it helping to carry out? maintaining homeostasis.
a change or signal in the enviornment that can make an organism react is called an stimulus.
What part of the brain controls memory? cerebrum
A synapse is the space between an axon and hte structure that recieves the nerve impulse
The three regions that make up the brain include the cerebrum, cerebellum, and brain stem
What are the products of photosynthesis? oxygen and sugars
What happens during photosynthesis? The cell uses the energy in sunlight to make food.
How does photosynthesis benefit heterotrophs? It creates food that they can eat.
What happens during respiration? Glucose is broken down, releasing energy.
How are photosythesis and respiration related? The have opposite equations
Together, respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere constantly changing
Consumers that eat both plants and animals are called? omnivores
Which is a consumer that is a herbivore? deer
