Answer:
Question 1: A Chordate
Question 2: C Sea Anemones
Question 3: B Lobster
Question 4: A Arachnid
Explanation:
Chordates are all the animals that have vertebrates (backbones)
The phylum Cnidaria includes those that have cnidocytes which are specialized cells for capturing prey. This includes sea anemones, jellyfish, and coral.
Arthropods are those that have an exoskeleton, segmented body, and paired jointed appendages like lobsters and other crustaceans.
Arachnids are animals that have eight legs, like spiders.

Answer:
Super-repressor (Is) - Uninducible dominant
Binding region is modified by the protein called repressor which prevents the lactose to bind with it. Thus, even the lactose is present the repressor protein is bound to the promoter and can not be detach from it. Transcription is not inducible.
Promoter mutation (P)- - Uninducible recessive
Mutated promoter region inhibits the binding of RNA polymerase that leads to trranscription.
The lacZ gene (
Z-) is mutated - recessive while the normal LacZ gene (Z +) - dominant
.
Inducible (Wild type) No expression (Mutant)
F' lac+/ Is No Yes
F' lac + / P- Yes No
F' lac + / Z- Yes No
F' lac +/ Mutation1 Yes No
F' lac+ / Mutation2 No Yes
Mutation 1 and F' plasmid - Inducible wild type
Mutation 2 and F' plasmid - Mutant no expression
