Q

Porifera

A

Pore filers organism for water that leaves cavities

Water flows through by choanocytes that are flagellated and woo their flagella that draws water in through pores and out through exit. They filter the water for food

Phagocytosis occurs by choanocytes and then transport particles to a different cell ameovpcyte

Q

Triploblasts

A

Include ectoderm and endoderm but also mesoderm

23
Q

Body cavity

A

Is another way to classify animals

24
Q

Coelomates Aceolomates

A

Animals with true body cavity

Acoelomates don’t have it

25
Q

What does a body cavity allow for

A

The moving around of tissues without rubbing on each other.

It’s a fluid filled space that reduces friction.

Within body we have serous membrane like our pericardia that doesn’t allow beat of heart to rub against lung

26
Q

Metezoa means

A

Animals

They are enterchangable

27
Q

Eumetazoa

A

Every animals except sponges or porifera

28
Q

Bilaterians

A

Humans are apart of this

bilateraly symmetrical animals

Subgroup within eumetozoa

29
Q

Deuterostomia

A

Stoma means mouth so all bilaterians are this.

This means mouth developed second so anus first The other is protistoms which means mouth first

Humans are apart of this

This leads to phylum leval of chordates for humans

30
Q

Chordates have hallmarks of what structure

A

They are names for a notochord

Kinda stiff but flexible rod allowed for muscles to pull on notochord to slow for efficient swimming

Dorsal hollow nerve chord
Nervous tissie that develops on the
develops into spinal chord

All have post anus tail

Ferengial slits

31
Q

Chordates that are not vertavrates

A

lancelets look almost u change from ancestor

Tunicates or sea squirt

32
Q

More specifically than chordates we are what

A

Vertebrates with vertable column

33
Q

The separations of vertebrates is

A

Jaws mineralized skeleton

34
Q

Gnath

A

Jaw or Agnatha no true jaw

35
Q

Gnathestoms

A

Means jawed fishes

Humans are this

36
Q

Pter

A

Means winged

37
Q

Actinistoa

A

Lobbed liked muscular fins. Compared to the spiny actinopterygii

humans are this

38
Q

Tetrapods

A

Four appendages which have digits

Humans are this

Animals lineages that invaded the land

Humans specifically in this are mammals

39
Q

Two major types of tetrapods

A

Amphibians

40
Q

Arthropods

A

Animal phylum that is most successful with the most adaptive radiation. Means jointed legs

Led to insects which are most animals alive today found almost everywhere where organisms are found except for the ocean.

41
Q

Insects wings are derived form

A

Not the legs. They keep their legs which make them so advantageous

42
Q

Amniotes include only

A

Reptiles and mammals not amphibians

Includes humans

43
Q

Amphibians live

A

Part of their life on land and part of their life on water

Leg eggs that are soft shelled that need to be layed in water

44
Q

Cleodoic

A

Hard shelled egg. Frees up for dependence of water and allows for oxygen and carbon dioxide to go through

45
Q

Amniotes have 4 extre embryonic membranes

A

Amnion -Around the embryo and reduces shock

Allantois - waste dump

Yoke sack- food supply

Chorian- got gas exchange like lungs

46
Q

3 major groups of mammals

A

Monetremes
Marsupials
Eutherians

Mammy have mamery glands that’s produce milk for young

47
Q

Monetremes don’t have

A

Nipples

Milk just oozes out of skin

They also leg hard shell eggs

Lower body temp and metabolism

48
Q

Marsupials

A

Immature blob of tissue gets born through vagina and then is somehow able to know to crawl up to the pouch and leach to nipple and developes more and almost is born again

49
Q

Eutherians

A

Uterus development and undergo a lot

Almost ready to be on there own

50
Q

Primates

A

Eutherians with manipulitable fingers and toes

51
Q

Apes

A

Doesn’t include monkeys

This includes humans

52
Q

Homo

A

Genus within apes

Chimpanzees have different genus it closest living relative

53
Q

Sapiens

A

Our species name

For humans

Apps that wear cloths

54
Q

Convolution

A

An example is when a moths probascis that is able to go up long tube like part of flower for nectar.

Specialized for a species organisms that are evolving together to leave out other organisms
