1Good somatic cells [blank_start]increase[blank_end] the chances of [blank_start]germ[blank_end] cells being passed forward.
- Aincrease
- Bgerm
2All vertebrates go through a common stage where they look similar, this is called...
- APharygula Stage
- BPhylotypic Stage
3All iinvertebrates go through a common stage where they look similar, this is called...
- APharyngula Stage
- BPhylotypic Stage
4Through similarities in development it was found that barnacles are...
- AArthropods
- BMolluscs
5The discovery of a [blank_start]notochord[blank_end] in sea squirt concluded they were related to [blank_start]vertebrates[blank_end], as the notochord is conversed within vertebrates. Means all vertebrates have a [blank_start]common[blank_end] ancestor.
- Anotochord
- Bvertebrates
- Ccommon
6Analogous...
- ATwo organisms look the same but have different origins (Shark = fish, Dolphin = mammal)
- BWhen two features have similar roles but evolved independently and have no common ancestors (Wings in bats and birds)
7Convergence...
- AWhen two features look similar but evolved independently from one another and have no common ancestor (Wings in bats and birds)
- BTwo organisms look the same but have different origins. (Shark - Fish, Dolphin - Mammal)
8Triphloblast
- A3 germ layers
- B2 germ layers
9Diphloblast
- A3 germ layers
- B2 germ layers
10The [blank_start]mesoderm[blank_end] evolved last. The mesoderm is encoded by the gene [blank_start]brachyury[blank_end] and is expressed around the [blank_start]blastopore lip[blank_end] where the mesoderm begins development. Despite [blank_start]diphloblastic[blank_end] organisms not having a mesoderm they still express brachyury, showing it existed in vertebrate ancestors.
- Amesoderm
- Bbrachyury
- Cblastopore lip
- Ddiphloblastic
11Deutrostome...
- AGastrulation occurs on dorsal and anus develops first (from blastopore lip) then mouth - e.g. humans
- BGastrulation occurs on ventral and mouth develops first (from blastopore lip) then anus - insects
12Protostome...
- AGastrulation is dorsal, anus forms first (from blastopore lip) and then the mouth develops - humans.
- BGastrulation is ventral, mouth forms first (from blastopore lip) and then the anus develops - insects.
13BMP causes [blank_start]ventral[blank_end] and chordin causes [blank_start]dorsal[blank_end]. Chordin inhibts BMP, if BMP overexpressed [blank_start]ventralisation[blank_end] occurs.
- Aventral
- Bdorsal
- Cventralisation
14Studies of the [blank_start]acorn[blank_end] worm shows that the BMP-Chordin axis of deutrostomes is [blank_start]inverted[blank_end], as it is a primitive deutrostome and its development is like a [blank_start]protostome[blank_end].
- Aacorn
- Binverted
- Cprotostome
