The balanced maintenance of an organism’s internal environment is called:
compensating
homeostasis
balancing
routine
The group of organisms that use the process of homeostasis includes
mammals, only
animals, only
plants and animals
all living things
Which of the following is not an examples of an organism maintaining internal homeostasis?
Shivering when cold
Sweating when hot
Going for a walk
Vomiting - releases toxins and wastes
A correct balance of oxygen and carbon dioxide must be maintained in the human body to survive. Which system is responsible taking in oxygen and releasing carbon dioxide to the external environment to maintain this internal balance?
the respiratory system
the circulatory system
the digestive system
the nervous system
Which of the following could help you maintain homeostasis?
Going to school
Sweating
Taking a test
All of the above
A football player perspires during a football game. The sweat is a cooling mechanism. What is this an example of?
Digestion
Mitosis
Homeostasis
Respiration
Why does your heart beat faster when you exercise?
To provide your muscle cells extra oxygen
To provide your muscle cells extra carbon dioxide
To heat your body up
To make you feel more tired
Which of the following resources are NOT needed by ANIMALS to help them maintain homeostasis?
oxygen
water
food
carbon dioxide
The ultimate cause of death
Over Heating
Diabetes
Bad Hair
Loss of Homeostasis
Things in the human body that need to stay the same
Glucose
Temperature
Blood Pressure
All of the above
The organ responsible for producing insulin is...
Liver
Heart
Pancreas
Gallbladder
Homeostasis is the way the body
maintains a stable internal environment
controls blood sugar
controls the brain
controls the endocrine system
Homeostasis happens whether or not we are thinking about it.
True
False
Can long periods of time without homeostasis create health problems for an organism?
Absolutely! Our bodies work hard for balance! :D
No way! We don't need that thing! >:(
Homeostasis really is not that important. :/
Two good examples of how homeostasis maintains our body are...
blood glucose (sugar) level and body temperature
brain waves and muscular growth
blood flow and body temperature
What is homeostasis?
the ability to go into chaos rather than balance
the state of change in an organism
the tendency to resist change in order to maintain a stable, relatively constant internal environment
The survival of a cell depends on the cell maintaining homeostasis. What is most likely to happen to a cell if homeostasis is not maintained?
The cell will immediately divide.
Cell processes will continue unchanged.
The cell will eliminate wastes more efficiently.
Many chemical reactions in the cell will slow down or even stop
How can hibernation help an organism maintain homeostasis?
The animal consumes more food during the winter in order to survive.
All body processes slow down in order to help the animal survive through cold temperatures.
Most body processes stop completely during cold weather, then start again during warm weather.
Most body processes speed up in order to help the animal generate heat through the cold winter.
Organisms can respond to changes in their environment in order to maintain a balance, called homeostasis. What does a tree do to maintain homeostasis during the winter months?
shivers
hibernates
absorbs sun
loses leaves
