Studied by 1 personCartilage
________ is a strong but flexible tissue that consists of scattered cells in a gel- like matrix of polysaccharides and protein fibers.
Pharyngeal slits
________ or pouches, which are openings into the throat or pouches in the throat.
Echinoderms
________ have a unique series of branching, fluid- filled tubes and chambers called the water vascular system.
Cephalochordates
________ are also called lancelets, or amphioxus; they are small, mobile, torpedo- shaped animals with a "fishlike "appearance, and they make their living by suspension feeding.
flexible rod
A notochord, a stiff and supportive but ________ that runs the length of the body.
Bone
________ is a dense tissue consisting of cells and blood vessels encased in a matrix made primarily of calcium phosphate, along with a small amount of protein fibers.
Chordates
________ are deuterostomes characterized by the presence of four key morphological features at some stage in their life cycles:
Urochordates
________ are also called tunicates.
Ecological context
________ is important for evolution.
Central

hominins
The ________ are a monophyletic group comprising Homo sαpiens and more than 20 extinct, bipedal relatives.
Endoskeleton
________ is a hard structure located just inside a thin layer of epidermal tissue, or skin, that protects and supports the body.
early embryonic
The deuterostomes (literally,"second- mouth) "were initially grouped together because they appeared to undergo ________ development in a similar way.
post anal tail
A muscular, ________, meaning a tail that contains muscle and extends past the anus.
milk nourishes
The ________ developing young, by a process called lactation.
Evolution
________ is not a linear progression from simple to complex.
mammalian placenta
The ________ is an organ combining maternal and embryonic tissues.
tetrapods
The first ________ to live on land were amphibians.
Tube feet
________ are elongated, fluid- filled appendages, each consisting of a balloon like ampulla inside the body and a tube- like podium projecting on the outside.
mammalian lineage
The ________ known as primates traditionally consists of two main groups: prosimians and anthropoids.
Echinoderms
________ are deuterostomes that share several synapomorphies- traits that identify them as a monophyletic group: radial symmetry in adults, an endoskeleton of calcium carbonate, and the water vascular system.
Mammals
________ are endotherms " (inside- heated) "that maintain high body temperatures by oxidizing large amounts of food and generating large amounts of heat.
