EXAM1 UPDATED ACTUAL Questions and CORRECT
Answers
Which of the following would not be an example of Increasing urine production when blood pressure is too low.
negative feedback maintaining homeostasis?
Which of the following is a good example of negative When you are hot, you sweat more until you cool down.
feedback?
Which of the following is a good example of Your blood pressure has been around 115/75 mm Hg for many years.
homeostasis?
In a damaged blood vessel, chemicals are released that This is positive feedback assisting a physiological process.
make clotting proteins and platelets stick together. This
clumps more platelets and clotting proteins together
until the damaged area is plugged up.
Which of the following would be true of this process?
Which of the following is typical of positive feedback? It takes the body further away from the normal values.
What is the term for the center point of the acceptable The set point
normal range for one of our internal environmental
conditions in homeostasis?
Which of the following is not true about negative It changes the set point so the new conditions become the new normal.
feedback?
Which of the following is an example of how positive Increasing oxytocin release causes more uterine contractions, which causes more
feedback may be used appropriately by the body? oxytocin release during childbirth.
, Imagine that a patient has dangerously low blood This is positive feedback and a failure of homeostasis.
pressure. This reduces the amount of blood returning to
the heart, so each subsequent beat pumps less blood.
This results in pressure dropping too low to adequately
supply the heart muscle with blood. The heart's pumping
becomes weaker and weaker, which further reduces
blood pressure.
Which of the following best describes what is happening
relative to homeostasis?
Which of the following would be an example of negative Release of thyroid hormone to increase metabolism when body temperature is
feedback maintaining homeostasis? too low.
What is the main goal of homeostasis? Maintain a relatively constant internal environment
Which of the following is always true of negative It always results in a response that reverses the stimulus that caused it.
feedback?
Which of the following would be an example of negative Release of a hormone to decrease high blood sugar levels.
feedback maintaining homeostasis?
Thermostats work with the HVAC unit in a building to The response is negative feedback in both cases.
blow cold air into rooms when it is too hot in the summer
in order to lower temperatures. The unit blows warm air
into rooms when it is too cold in the winter.
Which of the following would be true of the response to
the thermostat in both the summer and the winter?
Imagine you are doing yard work on a hot, sunny day. You It is positive feedback.
begin sweating to lose heat. But the sweat loss causes
you to become dehydrated, and that causes your blood
pressure to drop. In response, your body suspends
sweating to prevent your blood pressure from dropping
any more. Unfortunately, when you stop sweating you
also stop losing heat. Now your temperature begins to
rise, which increases your metabolic rate. That, in turn,
causes you to generate even more heat, and your
temperature rises still more. This is heat stroke.
Which of the following best explains the feedback that
occurs during heat stroke?
View this video on Biological Hierarchy of Organization Organelle
and answer the following question.
Moving from simpler to more complex, which level of
organization is immediately before (simpler than) the
cell?
Considering the principle of Form Fits Function, which of They contain proteins arranged lengthwise that slide back and forth across each
the following allows muscle cells to shorten or contract other
to produce movement?
