Answer: C.) Cladistics is based purely on the shared characters between organisms and their ranking in evolutionary history.
Explanation:
Phylogeny is the evolutionary science which derives a relationship among the ancient species with their descendants based upon common genetic, physiological and morphological characteristics. Cladistics represent the study of a group of organisms which exhibit a common ancestor. A clade includes organisms having a common ancestors and exhibit similar traits in them. A clade is sufficient to include the organisms in a phylogenic tree based upon their evolutionary history.
Cladistics is the approach used to classify the organism based on their shared characters on the basis of which the closely related organisms are grouped together.
The evolutionary biologist studies the physiological, genealogical, molecular and morphological characters on the basis of which the phylogenetic trees are constructed. In phylogenetic trees, the organisms are arranged according to their evolutionary history.
The stem 1.is responsible for the transport of food and water from the roots and leaves to the other parts of the plant 2. The stem holds the plant upright or erect 3. It also stores the nutrients 4. It also produces new living tissues
