Question 1

cardiac output q typically increase in excersicing animals driven by cahnges in 
heart rate 
stroke volume 
both 
neither

Accepted Answer

both 
cardiac output is equal to frequency x volume 
frequency is the heart rate

Question 2

in ocean rift tube worms adapted to derive energy from chemautorphic bacteria the circulatory system is adapted to deliver __ to the bacteria 
carbon dioxide and H2s 
H2s 
Nitrogen and H2s 
o2 and H2s

Accepted Answer

o2 and H2s chemoautotrophic oxidze h2s and always need o2

Question 3

which gut fermentaion generally allows for greater energy extraction from cellulose

Accepted Answer

foregut

Question 4

among vertebrtes the most acidic stomach content is found in

Accepted Answer

scavengers because they eat  a lot of bacteria

Question 5

is the acidic gut more if an immune thing or digestive thing

Accepted Answer

immune thing

Question 6

you measrue the metabolic cost of verticle climbing in a campus squirrel by attaching a gas mask and having a squirll run on a vertical orientated mill. you measure the RQ = .96 this means what type of fuel for its metabolism

Accepted Answer

carbs 
Rq = 1 = carbs 
rq = .71 = lipids

Question 7

if a migrating hummingbird meets its energy needs by burning pure sugar it will use about __ oxygen as it would use if it were burning pure fat

Accepted Answer

the same amount 
differnet fuesl have differnet energy content 
all the different fuels weather it is lipids or carbs 
same amount of energy yields same amount of o2 therefore its the same since the energy is the same

Question 8

if we have .5 grams of carb and .5 grams of fat which has more energy

Accepted Answer

fat it is energy dense 
more energy and requires more o2 to use it up

Question 9

a rat will use a __ amount of o2 than a tiger in terms of (ml o2) / (gram hr)

Accepted Answer

greater than since it has gram hr 
but it would be the tiger use more o2 per hr if gram was not in there

Question 10

the surfae area to volume ratio of a shape produces a line with a slope of 2/3 on a log scale plot the slope of the surface are to length ratio will be

Accepted Answer

2 since intially it is 2/3 the 2 is the surface area and the volume was the 3 now the volume is being replaced with the length which is just 1 therefore its 2/1 = 2

Question 11

a migrating canda goose that flies 10 miles powered by metabolizing fat will use about ____ of fuel as a goose flying the same distance but powered by metabolizing protein. asumme the goose weighs the same

Accepted Answer

half as many g 
fat has 2x as much energy per gram as carbs and protein

Question 12

based on your knowledge of scaling cost of movement in animals you expect a laboratory rat to require __- o2 (ml o2 / m) to move 100 meters than a large dog

Accepted Answer

less 
because cost is total 
cost is higher in total for bigger animals

Question 13

for flying birds the minimum cost of flight per unit time is ___ the minum cost per unit distance

Accepted Answer

slower than 
look at the curve

Question 14

based on your knowledge of scaling cost of movement in animals you expect a laboratory rat to require __- o2 (ml o2 / g) to move 100 meters than a large dog

Accepted Answer

more 
becasue smaller animals require more o2 per g

Question 15

large sea turtles that maintain a wamr body core and cool peripheral tissues when swimming through the north atlantic ocean are best describes as

Accepted Answer

heterotherms body has strong regional temp

Question 16

if the Q10 for a lizard is 2.5 and you measure the metabolis rate as 50 ml o2 / g h at 5 degrees what do you expect its metabolic rate to be at 12 degrees 

use Rb = R a Q10 ^ tb-ta /10

Accepted Answer

95 ml o2 g h

Q10 = 2.5 
rb = 50 ml 
ta = 12 
tb =12

Question 17

for a cold climate mammal the slope of line 1 will probably be __ the slopr for a tropical mammal 

less negative 
the same as 
more negative

Accepted Answer

less negative (not as steep)

Question 18

a tropical bird will probably have __ lower critcal temp compared toa bird from a temperate climate with the same body temp 

higher 
same 
lower

Accepted Answer

higher tlc since the slope of one is steeper therefore tlc closer to bigger number for tropical hot animal

Question 19

a freshwater invertebrate is likely to be __ with respect to its enviroemnt 
mostly hyperionic 
mostly hypoionic 
completelt isonic

Accepted Answer

hyperionic 
freshwater is fresh not much things ionic 
so the animal has higher conentration of ions in it comapred to the enviroment making it hyperionic to the enviroment

Question 20

when transition from sea water to brackish water the concentration of serine in the body fluids of a perfectly omsmoreulating invertebrate will probably 

decrease 
increase 
stay the same

Accepted Answer

stays the same because the osmoregulator does not change its msom no matter the enviroment
