Final answer:
The question sparked by the phrase 'The size of a cell phone is a fit attribute' relates to a probable typographical error, as 'fit attribute' generally pertains to characteristics that determine a biological cell's fitness. The other statements provided are related to cell biology, centering on cell size, prokaryotic cell DNA, and the structure of cilia and flagella.
Step-by-step explanation:
The statement 'The size of a cell phone is a fit attribute' seems misplaced and is likely a typo related to the context of cellular biology. In cellular biology, the term 'fit attribute' does not apply to cell phones but could refer to the traits or features that contribute to a cell's fitness, or its ability to survive and reproduce.
In regards to the actual biology questions provided: True or False: For cells, a smaller size is generally more efficient. This is true, smaller cells can absorb nutrients and expel waste more efficiently due to a higher surface area-to-volume ratio. True or False: DNA is located in the nucleus of prokaryotic cells. This is false; prokaryotic cells do not have a defined nucleus; their DNA is found in the nucleoid region. True or False: Cilia and flagella stick out of the cell membrane but are not made of cell membrane themselves. This is true; cilia and flagella are appendages composed of microtubules and covered by the cell membrane, not made of it directly. Finally, to address the statement about the cell membrane, recall that the cell membrane plays a crucial role in protecting the cell, regulating what enters and leaves, and maintaining homeostasis.
