Answer:
The correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
Explanation:
Scientists could not use DNA evidences to make a complete phylogenetic tree of Icthyosaur as there are no blood samples or other DNA molecules to create DNA printing or mapping to create phylogeny with the modern dolphins. They only can be make similarities based on the morphological characteristics of these two groups.
Thus, the correct answer is - Take blood samples and use DNA evidence to determine a more complete phylogenetic tree
.
There is a recessive gene that skips a generation.
The assisted transport of a molecule through the cell membrane in deprived of expenditure of energy is facilitated transport. It transports molecules via specific trans membrane integral proteins because of being passive the facilitated transport does not directly require chemical energy from ATP hydrolysis in the conveyance step itself but rather molecules and ions move down their concentration gradient.
