It would take 500 cell divisions to produce 1000 cell from 1 cell
Answer:
A cladogram is a diagram used to show relations among organisms in cladistics. Cladograms were generated on the basis of DNA and RNA sequencing data, morphological characters and computational phylogenetics.
Cladogram helps to classify organisms on the basis of shared traits between the ancestors and its easy to find related ancestor from cladistics. cladistics also shows evolved characteristics of an organism and how they are related to their ancestors.
Whereas outward appearances cannot show the genetic changes occured in an organism and can provide wrong information about the ancestors.
Hence, Cladogram using DNA is more accurate than using outward appearances.
Angraecoid orchids and African Moths follow the principle of coevolution. This happens because they are dependent on each other completely. The moth spreads the pollen so that the orchids can reproduce and the orchid is a food source for the moth as it provides nectar
