Explanation
sea stars are star-shaped echinoderms belonging to the class Asteroidea

Explanation
Mesoderm: One of the three primary germ cell layers, the others being the ectoderm and endoderm

Explanation
Carcinogen may be due to the ability to damage the genome or to the disruption of cellular metabolic processe

Explanation
Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.

Explanation
Blood is a combination of plasma and cells that circulate through the entire body.

Explanation

Explanation
Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger that binds to autocrine receptors on that same cell, leading to changes in the cell.

Explanation
It is a type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic.
