Which do you think would adapt and survive overtime to a mass extinction? A starfish or an eel?
Harlamova29_29 [7]

Answer:

Starfish

Explanation:

This is an opinion questions, so there really isn't a right or wrong answer.  You could just as easily choose Eel.  Your task is to pick one and defend your reasoning.

I chose starfish because starfish have a long history of demonstrated adaptability to a wide variety of conditions.  Their armored skin protects them from a variety of predators, as does the poison that many of them contain.  They have the ability to regrow limbs, and even regrow entire starfish from certain body parts.  When it comes time to breed, starfish meet together in groups.  Each female releases a few million eggs from the gonads in each of her arms.  Each male then releases billions of sperm from each gonad in each of his arms, thus covering the eggs with sperm to fertilize them.

Inga [223]

A pond organism that is unicellular, contains membrane-bound organelles and possesses a flagellum is a PROTISTA. It is a unicellular kingdom.

The Protista kingdom is composed of eukaryotic single-celled unicellular organisms.

Flagellated protists are microorganisms having a tail-like projection known as flagellum.

The flagellum is a structure used for motion, thereby, in general,  flagellated protists are found in moist environments (e.g., ponds, fresh-water, etc).

A contractile vacuole will help this organism better survive in its moist environment by <u><em>preventing or stopping the cell from absorbing too much water from its moist environment.</em></u>

  • A contractile vacuole is an <em>organelle</em> that can be found in organisms that are said to be <u><em>single-celled (Unicellular organisms).</em></u>

  • One of the primary functions of a contractile vacuole is to absorb <u><em>excess water</em></u> from the protoplasm in the unicellular organism and release this water to the surrounding environment.

  • A contractile vacuole can be called the excretory organ of unicellular organisms. This is because it is involved in <u><em>osmoregulation.</em></u>
