Spineless Under Pressure
This category encompasses the vast majority of animals.
What is invertebrates?
Arthropods do this because their exoskeletons get too small for their growing bodies.
What is molt?
If a jellyfish reproduces sexually, this is the form it is in.
What is medusa form?
Four general characteristics of vertebrates.
What are
1. An endoskeleton composed of a skull encasing the brain and vertebrae that make up the backbone.
2. A closed circulatory system composed of a 2, 3, or 4-chambered heart and arteries, veins, and capillaries.
3. A nervous system with a lobed brain.
4.Individual male and female sexes.
Underhair is used for this.
What is insulation?
Because this cannot travel through a dry cuticle, the earthworm will suffocate without moisture.
What is oxygen?
When a crayfish loses a limb this is what happens.
What is the injury gets sealed off to prevent bleeding, and then a new limb regenerates?
A shark's skeleton is made from this, making it more flexible than some of those other skeletons.
What is cartilage?
Communication can occur whenever one individual passes information to another. This information can be a sound, odor, visual display, or touch. Animals use these signals to communicate these three things.
What are warnings, readiness to mate, and the boundaries of a territory?
Arteries carry blood this way, while veins carry blood the other.
What are away and to? (Arteries=away, Veins=to)
Insects do not need respiratory systems because of a complex network of these that allow air to travel throughout the body.
What are tracheas?
The 5 common characteristics among arthropods.
What are (1) exoskeleton (2) body segmentation (3) jointed appendages (4) open circulatory system and (5) a ventral nervous system?
These are the four functions of an echinoderm's tube feet and the water vascular system.
What are locomotion, respiration, circulation, and feeding?
These have the following five characteristics: covered with tough, dry scales, ectothermic, breathe with lungs throughout their lives, three-chambered heart with a ventricle that is partially divided, produce amniotic eggs covered with a leathery shell.
What are reptiles?
Fish use this to sense vibrations.
What is their lateral line?
An example of this would be a flatworm that has complex nervous and digestive systems, and must seek out and fully digest prey.
What is free-living?
(1) three pairs of walking (or jumping) legs (2) wings (3) three segments in the body and (4) one pair of antennae.
What are the 4 characteristics that set insects apart from other arthropods?
This is how sponges get their prey.
The six main characteristics of birds.
What are (1) endothermic (2) heart with four chambers (3) toothless bill (4) oviparous, laying an amniotic egg which is covered in a lime-containing shell (5) covered with feathers and (6) skeleton composed of porous, lightweight bones ?
When a female mates with a male and then lays an egg, this type of fertilization takes place and the type of development takes place.
What are internal fertilization and oviparous development?
Amebocytes play these four roles in the life of a sponge.
What are (1) help digest and transport nutrients (2) they help carry waste to be excreted (3) they bring necessary gases such as oxygen to the cells and (4) they form the spicules or spongin?
The 5 characteristics that set arachnids apart from other arthropods.
What are (1) four pairs of walking legs (2) two segments in body (3) no antennae (4) book lungs and (5) four pairs of simple eyes.
This is why cnidarians do not need respiratory or excretory systems.
What is because their body walls are so thin that gases diffuse right through them?
The five main characteristics of mammals.
What are
(1) hair covering the skin (2) reproduce with internal fertilization and usually viviparous (3) nourish their young with milk secreted from specialized glands(4) four-chambered heart (5) endothermic?
The three types of learning.
What are habituation, imprinting, and conditioning?
