Answer: The correct answer is b.
Explanation:
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.
By moving substances across membranes, transport proteins make everything from nerve impulses to cellular metabolism possible. Without transport proteins, for example, the sodium-potassium gradient that allows our nerves to fire would not exist.
