Ascientist was observing an unknown slide under an electron microsocope; he found a cell without a well-defined nucleus but with a thick cell wall and ribosomes. what type of cell could it be?
prokaryotic
eukaryotic plant cell
eukaryotic animal cell

Let's eliminate this one by one.

Animal cell does not have walls. So we can eliminate The third option.

Plant cells does have walls, but they also have well-defined nucleus. So we can eliminate the second option

The leave : A. Prokaryotic as the answer

hope this helps

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
