animals whose embryos have two types of tissue

animals whose embryos have three types of tissue

connection to digestive track ex: liver , gut

gives rise to skin and nervous system

in between endoderm and ectoderm middle of the skin ex muscles and organs

4 sources of evidence

Fossils, comparative morphology, comparative development, comparative geonomics

feed on a variety of organisms, including plants, animals, fungi, protists, archaea, and/or bacteria

digest organic matter in sediments

Hydrostatic skeletons

derive support from a flexible body wall in tension surrounding a fluid or soft tissue under compression. They occur mostly in soft-bodied organisms such as sea anemones, earthworms, and octopuses.

derive support from rigid structures inside the body, such as bones in vertebrates and spicules in sponges.

derive support from rigid structures on the outside of the body, such as the external armor of arthropods.

Many birds, sea turtles, sea slugs, and other animals can detect Earth’s magnetic field and use it as an aid in navigation

Some aquatic predators, such as sharks, are so sensitive to electric fields that they can detect electrical activity in the muscles of passing prey

Some birds can sense changes in air pressure, which may aid them in avoiding storms.

live on the outside of their hosts, usually have limbs or mouthparts that allow them to grasp the host

live inside their hosts and usually have simple, wormlike bodies

capture food by filtering out particles floating in water or drifting through air

species gives birth through live young

species deposited fertilized eggs

have four membranes with four distinct functions.

What is special about marcupials

Youngs spend more time developing on the outside the mothers body than on the inside

posses a ring of nerve cells around the mouth

sessile and saclike, whereas others are

Cephalochordates (lancelets)

look like fish but are benthic invertebrates; juvenile cephalochordates are planktonic larvae

acorn worms, which burrow in marine sands or muds and make their living by deposit feeding or suspension feeding

Key innovation in vertebrates

large, three-part brain, protected by a hard cranium

Question	Answer
Diploblast	animals whose embryos have two types of tissue
Tripoblast	animals whose embryos have three types of tissue
Endoderm	connection to digestive track ex: liver , gut
Ectoderm	gives rise to skin and nervous system
Mesoderm	in between endoderm and ectoderm middle of the skin ex muscles and organs
4 sources of evidence	Fossils, comparative morphology, comparative development, comparative geonomics
Detritivores	feed on dead organic matter
Herbivores	feed on plants or algae
Carnivores	feed on animals
Omnivores	feed on a variety of organisms, including plants, animals, fungi, protists, archaea, and/or bacteria
Most carnivores are	predators
Deposit feeders	digest organic matter in sediments
Mass feeders	ingest chunks of food
Hydrostatic skeletons	derive support from a flexible body wall in tension surrounding a fluid or soft tissue under compression. They occur mostly in soft-bodied organisms such as sea anemones, earthworms, and octopuses.
Endoskeletons	derive support from rigid structures inside the body, such as bones in vertebrates and spicules in sponges.
Exoskeletons	derive support from rigid structures on the outside of the body, such as the external armor of arthropods.
Magnetic field	Many birds, sea turtles, sea slugs, and other animals can detect Earth’s magnetic field and use it as an aid in navigation
Electric field	Some aquatic predators, such as sharks, are so sensitive to electric fields that they can detect electrical activity in the muscles of passing prey
Barometric pressure	Some birds can sense changes in air pressure, which may aid them in avoiding storms.
Ectoparasites	live on the outside of their hosts, usually have limbs or mouthparts that allow them to grasp the host
Endoparasites	live inside their hosts and usually have simple, wormlike bodies
Suspension Feeders	capture food by filtering out particles floating in water or drifting through air
Fluid Feeders	suck up or mop up liquids
Viviparous	species gives birth through live young
Oviparous	species deposited fertilized eggs
Amniotic eggs	have four membranes with four distinct functions.
Amnion	contains the embryo
The yolk sac	contains nutrients
Allantois	contains waste from the embryo
Chorion	allows gas exchange
What is special about marcupials	Youngs spend more time developing on the outside the mothers body than on the inside
Adult echnioderm	posses a ring of nerve cells around the mouth
Adult urochordates	sessile and saclike, whereas others are
Cephalochordates (lancelets)	look like fish but are benthic invertebrates; juvenile cephalochordates are planktonic larvae
Hemichordates	acorn worms, which burrow in marine sands or muds and make their living by deposit feeding or suspension feeding
Key innovation in vertebrates	large, three-part brain, protected by a hard cranium
