Cells of all organisms are able to maintain internal stability despite changes in their environment. What is the name for this internal stability?
osmosis
responsiveness
gradualism
homeostasis
What is the function of a cell membrane?
to protect and support the cell
to perform different functions in each cell
to control what enters and leaves the cell
to form a hard outer covering for the cell
_____ regulates the volume of water in the blood and also has an important role in eliminating wastes
Excretory system
Endocrine system
Respiratory
Nervous system
This system controls virtually all the body’s activities:
the endocrine system
the excretory system
the nervous system
the respiratory system
What could happen due to a failure in homeostasis?
The accumulation of waste products.
The loss of excess water from the body.
Maintaining excess levels of sugar in the blood.
All of the above are potential outcomes from a failure of homeostasis.
When blood glucose levels fall, insulin secretion is inhibited and glucose synthesis is stimulated. Which type of feedback loop is this?
negative
positive
neutral
Which three human-body systems coordinate the most to cause an arm to move?
nervous, muscular, skeletal
respiratory, muscular, digestive
skeletal, circulatory, immune
digestive, nervous, circulatory
How do the circulatory system and the respiratory system
depend on one another?
Oxygen collected by the respiratory system is carried
throughout the body by the circulatory system.
Solid wastes collected by the circulatory system
are carried throughout the body by the respiratory
system.
Nutrients collected by the respiratory system are
carried throughout the body by the circulatory
system.
Carbon dioxide collected by the circulatory system is carried throughout the body by the respiratory system.
Blood carries hormones throughout the body. What two body systems are at work here?
circulatory and endocrine
endocrine and nervous
excretory and integumentary
circulatory and respiratory
