To meet cellular needs for food, water, energy, waste removal, multicellular organisms have developed various specializations, such as organs, and organ systems.

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.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.

can i get the brainliest pls

explanation:

it takes hundreds of years to become stable.

if you have another question lmk.
