Viruses are obligate intracellular parasites that are not cells or organisms.
Viruses cannot manufacture ATP, nucleic acids, or proteins on their own.
Viruses must enter and take over a host cell to make copies of themselves.
Viruses are no

15.3- A Model for DNA Synthesis
o Enzyme responsible for DNA replication
o Polymerizes deoxyribonucleotides into DNA
o DNA Polymerase adds deoxyribonucleotides only to the 3 end.
o DNA Synthesis always proceeds in the 5 to 3 direction.

Experimental Design and Details
For part one, the spring mass system was setup as shown in figure 1. The narrow end of
the spring was suspended from the spring clamp. The position,
, was measured and
recorded at the lower end of the spring with no weig
In part one, the force table was used to find that the mass of equilibrant vector, 105
grams, and masses of x- component, 15 grams, and y- component, 103 grams. For the
equilibrium to exist both, of the force vectors must equal zero Part two,
The items need for this experiment were a Pasco rational system, Pasco super pulley,
Pasco mass and hanger set, and a stopping watch. Before beginning, the apparatus was made

The purpose of this experiment was to find the coefficient of kinetic friction, k. For this
experiment, a friction cart was dragged across a straight track at four different inclines to find the
average force for each angle after four trials.
In conclusion we were able to calculate the Center of Gravity once we found the direction
of the forces ( , position of the forces ( x) , and the amount of force on each sensor (F).
When we calculated our Center of Gravity, which was . 291 m ,
ConclusionIn conclusion, we calculated our frequency to be 51.37Hz. The main physic concept our
group discovered was the relationship between the frequency and the wavelength. Our
experiment was successful due to the fact that we calculated a frequency. A

Lab: Detection of Apoptosis
Cleavage of PARP-1 as an indicator of caspase activation
A central player in apoptosis is a family of aspartyl proteases
known as caspases. Caspases exist as zymogens in cells, and
become activated following apoptos
In the following weeks, we will be performing a series of timed experiments to determine the order of
events during apoptosis. These experiments will introduce you to theoretical knowledge and will give

Fungi are important as decomposers that break down dead organic matter, releasing
inorganic nutrients. Some are parasites of plants and animals, whereas others help plants
