Question 1

Resting metabolic rate? (RMR)

Answer 1

energy expenditure at rest but routine activities/day

Question 2

basal metabolic rate (BMR)

Answer 2

metabolism at complete rest- lowest possible

Question 3

standard metabolic rate (SMR)

Answer 3

METABOLIC RATE measured at a specified temperature (ectotherms)

Question 4

Field metabolic rate (FMR)

Answer 4

Metabolic rate measured in wild animals

Question 5

direct calorimetry?

Answer 5

heat loss

Question 6

indirect calorimetry?

Answer 6

O2 consumed or CO2 produced.

Question 7

isometric scaling

Answer 7

means dimensions increase at the same rate
a birds mass and beak length increasing proportionally means its isometric

Question 8

hypoallometric scaling

Answer 8

this occurs when one characteristic. (beak length) increases at a slower rate compared to another characteristic. (body mass)

Question 9

inverse scaling

Answer 9

inverse scaling implies that one variable increases while the other decreases

Question 10

hyperallometric scaling

Answer 10

one characteristic increases at a faster rate relative to another characteristic

Question 11

Vasodilation

Answer 11

Vasodilation involves the relaxation of smooth muscle cells within the blood vessel walls, leading to an increase in vessel diameter
in terms of thermoregulation it helps dissipate heat by increasing blood flow to the skin, allowing heat loss in warm environments

some triggers that might allow this to occur in the body is warm temperatures, decreased O2 levels, increased CO2 levels

Question 12

vasoconstriction
