•Cells with a higher ratio of surface area to volume can not sustain themselves more easily.
True
False
Diffusion is inefficient over longer distances
True
False
Cellular communication is more efficient in smaller cells.
True
False
The cytoskeleton transportation network becomes more efficient for a cell if the distance to travel becomes too large.
True
False
Chromatin is the relaxed form of DNA
True
False
The phosphate groups in DNA create a negative charge, which attracts the DNA to the positively charged histone proteins and form a nucleosome
True
False
The nucleosomes group together into chromatin fibers, which supercoil to make up the chromosome
True
False
