Question

1. Thermal biology is critical for determining where species live, how they deal with extremes in temperature, etc. Answer the following questions relating to thermal biology.

a. Provide the Heat Flux equation by defining the x’s in the equation: HTotal = H + Hx+ Hx+ Hx+ Hx

b.Address how poikilotherms acclimate to changing temperature for the following two parameters:

i. Membrane fluidity:

ii. Protein Function (4 pts):

iii. Membranes have approximately the same level of fluidity regardless if the animal is from the arctic, temperate, or equatorial regions: Circle one

a.True

b. False

Answer 1

b. Membrane fluidity is nothing but the chaging/altering the lipid head group attached to proteins

Poikilotherms present in the cold area have increased lipids in the membrane and vice versa

protein function

Protein in the membrane hold the lipid and help to alter it's head

They are useful in signalling reaction

They helpful in proper seperation of membrane during cell division

They are transversely spreaded

iii. False
