Dormancy
Hibernation
In _________ feedback, the change is BAD and needs to be corrected.
Positive
Negative
In _________ feedback, the change is considered GOOD and should be increased.
Positive
Negative
Which parts of the body are usually Effectors?
Sense Organs
Muscles & Glands
Control Center
Arms & Legs
Which of the following is an example of positive feedback?
Thermoregulation
Blood Pressure
Childbirth
Blood Sugar Levels
Which of the following is an example of negative feedback?
Lactation
Childbirth
Blood Clotting
Thermoregulation
Homeostatic cooling mechanisms include
piloerection and panting
panting and vasoconstriction
sweating and piloerection
sweating and vasodilation
Blood sugars are controlled by
brain generated chemicals
blood
hormones from the pancreas
chemicals from the liver
The hormone that makes the liver store sugars is
glucose
glycogen
glucagon
insulin
The liver normally stores blood sugar as
glucose
glycogen
glucagon
fats
An example of homeostasis is the regulation of the glucose sugar level in blood through the interaction of the hormones insulin and glucagon.
What happens if the body is unable to maintain its blood glucose level?
What is the main function of the kidney?
Remove urine from the body
To add salt to blood
Maintain water balance of the body
To break down proteins
Which situation best describes the act of maintaining homeostasis?
An organism sweating when their body temperature begins to rise
A plant on a window sill growing towards sunlight
A bear hibernating in the winter months
All of the above
Which type of feedback system is more common in maintaining homeostasis?
positive
negative
neutral
balanced
What type of feedback system is more dangerous to an organism?
