Many tropical zooplankton have elaborate spines. These have been interpreted as either a defense against predation or a means to

Answer:

Means to increase drag and prevent sinking is the correct answer.

Explanation:

Plankton avoid sinking by increasing their surface area and decreasing their density. Spines slow down sinking by adding surface area without increasing density. Defense against predation would be to sing below. Not the opposite.

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.
