,Muscle cells require more energy in order to function than
most other cells. Therefore, muscle cells would be
expected to have more ________ than most other cells. -
CORRECT ANSWERS ✔✔Mitochondria
Which of the following would most likely be associated
with the surface of cells and provide a brushing motion,
thereby moving materials over the surface of the cells? -
CORRECT ANSWERS ✔✔Cilia
Studies of nucleosomes have shown that histones (except
H1) exist in each nucleosome as two kinds of
tetramers: one of 2 H2A molecules and 2 H2B molecules,
