4.4 Transport By Carrier Protein
17. Describe Isotonic, Hypotonic, and Hypertonic Solutions.
And draw and
explain examples of each:
An isotonic solution is one where the solutions in the cell and the
surrounding area are equal, so there is no net movement

4.1 Plasma Membrane Structure and Function
1. What does fluid mosaic model describe?
The fluid mosaic model describes the plasma membrane. It says that the membrane has a
fluid consistency, with proteins scattered in and out of the phospholipid bilayer in
4.2 The Permeability of the Plasma Membrane
7. What does the term differentially permeable mean?
Differentially, or selectively, permeable membranes are ones that allow
some substances to move freely across the membrane, and prohibits others
from moving a
4.3 Diffusion and Osmosis
11. What is diffusion?
How does Figure 4.4 illustrate this? What does this
have to do with concentration gradient?
Diffusion is when molecules move from a high concentration gradient
to a low one. Figure 4.4 shows this by represe

We May Be Born with an Urge to Help
This article discusses the altruism inherent in human beings. It says that, while all
organisms must be innately selfish to a degree in order to survive, humans also express a desire
to aid those on need. It go
