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.

<h3>IgG: What Does It Mean?</h3>

Which Of The Following Most Accurately describe the result of cell division without differentiation?
suter [353]
Hmm...,
      Well from what I'm getting, I feel like the cell would just be replication itself. Cell differentiation is the process by which a cell gets placed, or destined, to become a particular type of cell.
    So, if a cell was to go undergo cell division with out cell differentiation, this most likely means it is going under the DNA replication process, AK.A- splitting the mother cell to create daughter cells.

A population of white, grey, and black lizards lives on a volcanic island, and each phenotypic color has an equal chance of surv
EleoNora [17]

I would say disruptive selection, because the sudden eruption of the volcano disrupted the circumstances of the lizards, allowing the black ones to survive better because of camouflage against the black rock.

Hope this helps!
