Derek was observing a specimen using a microscope. He observed a single cell on the slide. He noticed it was round in shape, with a nucleus in the middle of the cell, and a structure that the cell could use to move around. Derek concluded he was looking at an animal cell. His lab partner James disagreed and insisted that they were observing a unicellular protist. Who is correct, and which piece of evidence supports the correct claim? (1 point) Responses Derek; the cell has a nucleus and cell membrane Derek; the cell has a nucleus and cell membrane James; the cell was isolated by itself on the slide James; the cell was isolated by itself on the slide Derek; the cell is round in shape Derek; the cell is round in shape James; the cell has a structure that allows it to move independently
Derek is correct. The piece of evidence that supports Derek's claim is that the cell has a nucleus and a cell membrane, which are characteristics of animal cells.
whats the short answer
Derek is correct. The presence of a nucleus and a cell membrane supports the claim that the cell is an animal cell.
what is the shorter answer
Derek is correct.
is it Derek; the cell is a round shape.
No, the shorter answer would still be "Derek is correct." The evidence of the cell being round in shape is not sufficient to determine whether it is an animal cell or a unicellular protist.
why is derek correct
Derek is correct because the presence of a nucleus and a cell membrane supports the claim that the observed cell is an animal cell. This is a characteristic feature of animal cells, and it distinguishes them from unicellular protists.
Both Derek and James have valid points, but they need to consider additional evidence to come to a more accurate conclusion.
Derek's claim that it is an animal cell is supported by the presence of a nucleus and a cell membrane. Animal cells typically have a distinct nucleus and a cell membrane that separates the cell from the external environment.
James, on the other hand, argues that they are observing a unicellular protist. The fact that the cell was isolated by itself on the slide could suggest that it is a unicellular organism since protists are often single-celled organisms.
To determine who is correct, Derek and James should consider other characteristics of the observed cell. For example, they can look for other organelles or structures within the cell, such as chloroplasts, which would indicate photosynthesis and suggest a plant cell or algae. They can also examine the method of movement of the cell; if it uses flagella or cilia, it might imply a protist.
Overall, without additional evidence, it is difficult to definitively determine if the observed cell is an animal cell or a unicellular protist. Further investigation and examination of different cell features would be necessary to reach a more conclusive answer.
