Q

Vertebrate circ. system has how many chambers in heart in AMPHIBIANS?

A

3 chambered heart, 2 atria 1 ventricle

26
Q

Circulation on amphibians?

A

Double circulation - Pulmocutaneous circuit and Systemic circuit!

27
Q

Adv. of amphibian closed circa system?

A

higher pressure blood going into tissues-2 heart beats-gills and lungs

28
Q

Adv of reptile closed circa. system?

A

minimizes mixing of deoxinated blood and oxygenated blood.

29
Q

Adv of closed circa. system in birds and mammals?

A

no mixing of blood o2 blood only goes to body.

30
Q

REPTILE & BIRDS AND MAMMALS closed circa. system?

A

double circ., pulnmoary ciruit, systemic circuit

31
Q

REPTILE HEART?

A

3 chambered-ventricle has a partial septum

32
Q

BIRDS AND MAMMALS HEART?

A

4 chambered, complete septum

33
Q

What is osteophagia?

A

to eat bone

34
Q

Substrate feeding?

A

earthworm, apple maggots, leaf miner insects eat mesophyll in leafs

35
Q

Fluid feeders

A

specialized mouth parts - aphid, mosquito

36
Q

Specialized blood fluid feeders

A

anticoagulants

37
Q

Advantages of bulk feeding?

A

much more surface area for enzymes to work, better digestion

38
Q

Herbivores incisors used for?

A

cutting

39
Q

Carnivores molars needed?

A

no

40
Q

Carnivores premolars?

A

shearing

41
Q

What are requirements for gas exchange?

A

moist surface, adequate surface area-larger animals have more cells

42
Q

What phyla do gas exchange by diffusion?

A

Porifera, Cnidaria, Platyhelminthes

43
Q

Who uses cuteness respiration

A

amphibians, not completely aquatic

44
Q

Concurrent gas exchange aquatic

A

water with blood moving in the same direction

45
Q

countercurrent exchange

A

is efficient, better use of o2

46
Q

Exhalation produces pos pr neg pressure

A

positive

47
Q

Inhalation produces

A

negative pressure, diaphragm contracts

48
Q

Products of waste removal fish?

A

ammonia

49
Q

Product of waste removal squirrel

A

urea

50
Q

product of waste removal birds

A

uric acid

51
Q

Dendrites

A

where info is entering the cell

52
Q

Axon

A

output

53
Q

Sensory neurons

A

carry info from body to CNS

54
Q

Interneurons

A

carry info entirely within CNS

55
Q

Motor Neurons

A

carry info away from CNS carry to some target organ in the body

56
Q

A “resting” motor neuron is expected to

A

exhibit a resting potential that is more negative than the “threshold” potential. 

57
Q

THe “threshold” potential of a membrane

A

is the minimum depolarization needed to operate the voltage-gated sodium and potassium channels.

58
Q

The ʺslow blockʺ to polyspermy is due to

A

formation of the fertilization envelope.

59
Q

The vegetal pole of the zygote differs from the animal pole in that

A

the vegetal pole has a higher concentration of yolk.

60
Q

The yolk of the frog egg

A

supports the higher rate of cleavage at the animal pole compared to the vegetal pole.

61
Q

The sequence of developmental milestones proceeds as follows:

A

cleavage → morula → blastula → gastrula

62
Q

an open space within the gastrula is the

A

cells. archenteron
