Which sequence best represents the different levels of organization of multicellular organisms from least complex to most complex? a. cell ⇒ organ ⇒ tissue ⇒ organ system ⇒ organism b. cell ⇒ tissue ⇒ organ ⇒ organ system ⇒ organism c. organism ⇒ organ system ⇒ organ ⇒ tissue ⇒ cell d. organism ⇒ organ ⇒ organ system ⇒ tissue ⇒ cell

the answer is B

The correct answer is option A, S Phase - DNA Replication

The DNA replication begin at the S phase of the cell cycle. In this phase, the cell grows and prepare itself for the DNA replication while the other components such as centro some undergo replication. The S phase occurs during the inter phase and the genetic material duplicates itself before entering the mitosis and meiosis cell division in the next stage.
