correct Denotations |
Animal Diversity - Correct answer ✔refers to a group of the same kind of
| | | | | | | | | | | | | |
animal in which there are lots of animals with different traits
| | | | | | | | | |
Tree of Life - Correct answer ✔A diagram depicting the genealogical
| | | | | | | | | | |
relationships of all living organisms on Earth, with a single ancestral species at
| | | | | | | | | | | | |
the base.
|
Hypothesis for animal orgins - Correct answer ✔Various studies suggest that
| | | | | | | | | | |
animal diversification began more than a billion years ago. The common
| | | | | | | | | | |
ancestor may have resembled modern chroanoflagellates, proists that are the
| | | | | | | | | |
closest living relatives of animals, and was probably itself colonial, flagellated
| | | | | | | | | | |
protist
Characteristics that define an animal - Correct answer ✔Animals are | | | | | | | | | |
multicellular, heterotrophic, eukaryotes with tissues that develop from
| | | | | | | |
embryonic layers, lack cell walls, held together with by structural proteins aka
| | | | | | | | | | | |
collagen, have muscle and nerve cells, and most reproduce sexually
| | | | | | | | |
Role of Hox genes in animal development - Correct answer ✔- Regulate
| | | | | | | | | | | |
expression of other genes that influence animal morphology and contain
| | | | | | | | | |
common modules of DNA sequences
| | | | |
-expression of dozen of other genes that influence animal morphology
| | | | | | | | |
,Significance for the Cambrian Explosion - Correct answer ✔about half of extant
| | | | | | | | | | |
animal phyla arose from this and underwent considerable diversification
| | | | | | | | |
Three hypotheses for the cause of the Cambrian explosion - Correct answer ✔1.
| | | | | | | | | | | | |
new predator-prey relationships
| |
2. atmospheric changes
| |
3. development flexibility
| |
5 major features of animal phylogeny - Correct answer ✔1 all animals share
| | | | | | | | | | | | |
common ancestor |
2. sponges are basal animals
| | | |
3. eumztaeoa is a clade of animals with true tissues
| | | | | | | | |
4. most animal phyla belong to the clade Bilateral
| | | | | | | |
4. chordates and some other phyla belong to the clade deuterostomia
| | | | | | | | | |

| | | | | | | | | | |
the gut and outer body wall
| | | | |
anterior - Correct answer ✔the head of a bilaterally symmetrical animal
| | | | | | | | | |
archenteron - Correct answer ✔The endoderm-lined cavity, formed during the
| | | | | | | | | |
gastrulation process that develops into the digestive tract of an animal
| | | | | | | | | |
bilateral symmetry - Correct answer ✔characterizing a body form with central
| | | | | | | | | | |
longitudinal plane that divides the body into two equal but opposite halves.
| | | | | | | | | | |
,bilaterian - Correct answer ✔member of the clade Bilateria, animals with
| | | | | | | | | | |
bilateral symmetry |
blastopore - Correct answer ✔the opening of the archenteron in the gastrula
| | | | | | | | | | | |
that develops into the mouth in the protosome and the anus in deuterostome
| | | | | | | | | | | |
blastula - Correct answer ✔the hollow ball of cells marking the end stage of
| | | | | | | | | | | | | |
cleavage during early embryonic development
| | | |
body cavity - Correct answer ✔a fluid-containing space between the digestive
| | | | | | | | | | |
tract and the body wall
| | | |
body plan - Correct answer ✔in animals, the set of morphological and
| | | | | | | | | | | |
developmental traits that define a grade | | | | |
cephalization - Correct answer ✔an evolutionary trend toward the | | | | | | | | |
concentration of sensory equipment on the anterior end of the body | | | | | | | | | |
cleavage - Correct answer ✔the process of cytokinesis in animal cells,
| | | | | | | | | | |
characterized by pinching of the plasma membrane; specifically the succession | | | | | | | | | |
of rapid cell divisions without growth during early embryonic development that
| | | | | | | | | |
converts the zygote into a ball of cells
| | | | | | | |
coelom - Correct answer ✔a body cavity completely lined with mesoderm
| | | | | | | | | |
, coelomate - Correct answer ✔an animal possessing a true coelom
| | | | | | | | |
determinate cleavage - Correct answer ✔a type of embryonic development in
| | | | | | | | | | |
protosomes that rigidly casts the developmental fate of each embryonic cell very
| | | | | | | | | | |
early
|
protosome development - Correct answer ✔in animals, a developmental mode
| | | | | | | | | |
distinguished by the development of the mouth from the blastopore; often also
| | | | | | | | | | | |
characterized by schizocoelous development of the body cavity and by spiral
| | | | | | | | | | |
cleavage
diploblastic - Correct answer ✔having two germ layers
| | | | | | |
dorsal - Correct answer ✔pertaining to the back of bilaterally symmetrical
| | | | | | | | | | |
animals
ecdysozoan - Correct answer ✔member of a group of animal phyla with
| | | | | | | | | | | |
protosome development that some systematist hypothesize for a clade
| | | | | | | | |
including many molting animals
| | |
ectoderm - Correct answer ✔outermost of the three primary germ layers in
| | | | | | | | | | | |
animal embryos; gives rise to outer covering an din some phyla the nervous
| | | | | | | | | | | | |
system, inner ear, and lens of the eye
