Viruses are extremely small infectious agents that invade cells of all types.
Once inside another cell, viruses become hijackers, using the cells' machinery
to produce more viruses. Whether viruses constitute living organisms or
merely conglomerations of
Mitosis is the process where cells divide to produce
new cells. If you cut your hand, new cells are
produced to heal the wound. These new cells are
produced through this process of mitosis. Your body
is continually producing new cells to replace old ones

Controls traffic in & out of the cell: allows some substances to cross more easily than
PHOSPHOLIPIDS 2 fatty acid tails, phosphate group head, joined via glycerol
How does different wavelength of light effect the activity of DCPIP?
Hypothesis: White light will have the lowest DCPIP activity correlating to the photosynthesis
activity being increased.
Photosynthesis is a process of converting light energ

Are antibiotics the hero or villain?
The challenge of antibiotic resistance: Has our use of Antibiotics caused more problems than
I has solved?
There have been both positive and negative changes made to the human health since the
introduction of antibioti

Unlike eukaryotic cells, prokaryote cells lack membrane-bound organelles. However, whereas
prokaryote cells are less structurally complex than eukaryotes, they are more chemically complex,
since all of the prokaryote cell's biomolecules are floating aroun
Cell membranes are very important structures to cells because they function
as a barrier between the components of the cell and the outside environment.
The cell membrane is not only responsible for creating a wall between inside
and outside the cell, it
there are different classes of cells. In this short section, we will discuss the
major cellular differences between prokaryotic and eukaryotic cells, and
between animal and plant cells. The diversity among various cells is a result of
the varying function

ukaryotes differ from prokaryotes in the level of their structural complexity.
Whereas the simpler prokaryotes contain all their genetic material, such as
DNA and RNA, within the cell membrane, eukaryotes have intracellular

The cytoskeleton is similar to the lipid bilayer in that it helps provide the
interior structure of the cell the way the lipid bilayer provides the structure of
the cell membrane. The cytoskeleton also allows the cell to adapt. Often, a
