Answer:
The correct answer will be- true and structural specializations
Explanation:
The evolution of life on earth has suggested that life has moved from the simplicity to complexity or from single-celled organism to multicellular organism.
This multi-cellularity is achieved through the property of called cellular differentiation and specialization. as the cellular complexity increases, therefore, cellular demands like the use of energy, food, water and other variables increased.
This lead to the formation of the organ and organs system specializes to perform specific functions like the digestive system and another biological system.
Thus, true and structural specializations are the correct answer.
Answer:
Craniates
Explanation:
Vertebrate animals - representing the subphylum Craniates, as its name implies, are those animals that have as their main characteristic the spine. This structure is responsible for shaping, balancing and protecting the nerve cord.
Vertebrates are a phylum part of chordates, but pay attention, as not every chordate is a vertebrate animal. Vertebrates are fish, amphibians, reptiles, birds and mammals. Hagfish, lamprey, sharks and tuna are an example of chordates that have a spine and can be classified as Craniates.
