Answer:
Lobe-finned fish are thought to be the close relatives to tetrapods because of the fact that the fins are very flexible and potentially useful for supporting the body on land, as in lungfish and tetrapods.

Answer:
1/10^4
Explanation:
Given that 500 colonies were observed on ampicillin plate after transformation. 1 colony represents 1 transformed bacteria because each colony is assumed to have grown from one single bacteria. Hence, 500 bacteria had transformed from 5*10^6 bacteria.
Fraction of cells that got transformed = (Number of cells that were transformed/ Number of total cells)
= 500/(5*10^6)
= 1/10^4
Hence, 1/10^4 cells were transformed in experiment.
