Hey,
Looking to get the following answered.
Thanks :D
HOMEOSTASIS
1 Homeostasis is best described as:
a) the maintenance of a steady state in the environment despite changes within the body
b) the ability of the body to regulate heat and remove waste products
c) the ability of the body to maintain a steady state despite changes in the environment
d) the regulation of water in the tissues and the removal of waste products
2 Which of the following does not allow an animal to reduce its body temperature?
a) sweating
b) panting
c) shivering
d) vasodilation
3 Which of the following will allow an animal to retain body heat?
a) sweating
b) vasodilation
c) vasoconstriction
d) all except c)
4 The kidney helps control water balance in the body under the influence of which hormone:
a) anti-diuretic hormone (ADH)
b) oxytocin
c) prolactin
d) adrenaline
5 The acid-base balance (the pH of the blood) is strongly affected by the level of what in the bloodstream?
a) protein
b) carbohydrate
c) oxygen
d) carbon dioxide
2
6 Arrange the following heat regulating mechanisms under the appropriate heading for heat retention or heat loss.
a) increasing muscular activity b) panting
c) piloerection d) reducing muscular activity
e) shivering f) sweating
g) vasoconstriction h) vasodilation
Heat retention Heat loss

7 From the list below identify which body functions take place if an animal has an increased loss of fluid. Cross out the description that does not apply.
Increased/Decreased Thirst
Dilation/Constriction Of blood capillaries
Increased/Decreased Release of anti-diuretic hormone
More/Less Fluid reabsorbed in kidney tubules
Increased/Decreased Urine concentration
8 Complete the following statement using the word list then answer the question below:
wordlist
blood plasma, tissue fluid
The acid-base balance of the _________________________ needs to be kept within a certain pH range because the composition of the _________________________ depends on it.
9 If the environment of the body cells is not kept constant within narrow limits what will happen to the cells?
