Answer: Tetrapods
Explanation:
Tetrapods are the most recent common ancestor with the lungfish look like.
Ancient species of lung fish are the ancestors of tetrapods. These fish may live on land, breathing air and being propelled by their pelvic fins. Australia has three populations of the few remaining lungfish — two marine populations and one inhabiting the Mary River basin in Queensland.
Hence, tetrapods are most common ancestors with lung fish.

Answer:
Explanation:
The eukaryotic genes of interest can be expressed in the prokaryotic genome or plasmid vector. The following are the steps used for the purpose of expression of eukaryotic genes in the prokaryotic genome.
1. Amplification of the target gene of interest from the eukaryotic genome by PCR or polymerase chain reaction.
2. The selection of the plasmid and digestion of the plasmid DNA with the restriction enzyme.
3. Ligation of the amplified DNA fragment and the plasmid.
4. Introduction of the ligated plasmid into the prokaryotic host organism.
Answer:
26. Coal is burned at a power plant
27. In dams.
28. Gas heater.
29. Nuclear power plant.
Explanation:
Coal is burned at a power plant where Chemical energy is converted into thermal and then into electrical current. In dams, water falls from higher altitude in which Gravitational potential is converted to kinetic energy by revolving of turbines which produces electrical current. in heater, electrical energy is converted into radiant and also heat or thermal energy while the nuclear thermal energy is converted into electrical energy and this happen in the nuclear power plant.
