A

radial

19
Q

what type of germ layer do most animals have

A

triploblasts

20
Q

mesoderm

A

cells on both sides of the gut (endoderm)

21
Q

how does cloning work

A

diploid nucleus of genes that you want to duplicate is drooped into an egg

22
Q

what experiment was about cloning

A

Dolly

23
Q

transcription factors

A

stick to dna and promote or stop genes

24
Q

bicoid

A

front transcription factor

25
Q

nanos

A

back transcription factor

26
Q

Hox gene

A

genes that turn on structured genes

27
Q

how do you get multiple of the same hox gene

A

gene duplication

28
Q

the process of transformation from an immature form to an adult form in two or more distinct stages.

A

metamorphosis

29
Q

advantages to metamorphosis

30
Q

third germ layer

A

mesoderm

31
Q

what is a coelom

A

air or fluid cavity within the mesoderm

32
Q

what is the coelom adaptive for?

A

twisting or turning
open free space for organs to go

33
Q

first opening mouth develops from blastopore

A

protosomes

34
Q

second opening anal develops from blastopore

A

deuterstomes

35
Q

which one’s blastids are determinate, protostomes or deuterostomes

A

protostomes

36
Q

what kind of symmetry do protostomes have?

A

spiral

37
Q

what kind of symmetry do deuterostomes have?

A

radial

38
Q

how does the coelom formation happen in deuterostomes

A

folds of archenteron form the coelom

39
Q

what is the coelom called in a deuterostomes

A

entercoelous

40
Q

how does the coelom formation happen in protostomes

A

solid masses of mesoderm, split to for it

41
Q

what is the coelom called in a protostomes

A

schizocoelous

42
Q

acoelomates

A

Animals that do not have a coelom are called

43
Q

pseudocoelom

A

is a body cavity that lies between mesodermal and endodermal tissue and is, therefore, not completely surrounded by mesodermal tissue.
