Textbook Question
Chapter 1, Problem 1.2PS
QUANTITATIVE Cell Sizes. To appreciate the differences in cell size illustrated in Figure 1-3a, consider these specific examples. Escherichia coli, a typical bacterial cell, is cylindrical in shape, with a diameter of about 1 μm and a length of about 2 μm. As a typical animal cell, consider a human liver cell, which is roughly spherical and has a diameter of about 20 μm. For a typical plant cell, consider the columnar palisade cells located just beneath the upper surface of many plant leaves. These cells are cylindrical, with a diameter of about 20 μm and a length of about 35 μm.
(a) Calculate the approximate volume of each of these three cell types in cubic micrometers. (Recall that V = πr2h for a cylinder and that V = 4πpr3/3 for a sphere.) Use three significant figures for these calculations.
(b) Approximately how many bacterial cells would fit in the internal volume of a human liver cell?
(c) Approximately how many liver cells would fit inside a palisade cell?

Hypothesize which dialysis bags should gain, lose or stay the same in regards to volume. Explain.
Which solution is hypotonic, hypertonic and isotonic?
Explain what the change in volume of the dialysis tube indicated and describe what happened when the volume increased and when the volume decreased.

please choose correct letter and explain a bit
1. The strongest way by which a protein can maintain its shape is by using:a) ionic bonds
b) disulfide bonds
c) star war forces
d) van der Waals forces

a) glycoproteins
b) feet
c) microtubules
d) actin filaments
True or False: In eukaryotic cells (such as human cells), the variety and diversity of proteins is much less than the variety and diversity of lipids.
