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.

Ling made a study chart for science class.
aliina [53]

Alyssa's additional observation would be cell Y having a larger vacuole than cell X. The third option is the correct one.

<h3>Plant cell vs animal cell</h3>

From the observations, both cells are eukaryotic. This is because:

  • cell X has lysosomes which are only found in eukaryotic cells
  • cell Y has a nucleus which also peculiar to eukaryotic cells only

Lysosome houses digestive enzymes and is found mostly in animal cells. Only a few plant cells have lysosomes.

Thus, the lack of a lysosome means that cell Y is a plant cell while the presence means that cell X is an animal cell.

Generally, plant cells have larger vacuoles than animal cells.
