... dark prior to illumination?
The reason this was done was to make sure as little oxygen as possible was contained in the leaf material. This coused the experimrnt to run properly. If the leaf material was not placed in the dark, the dark reaction would not have occured using up all the oxygen. If there was still oxygen in the leaf material, the data collected would have been off. The reason for this is that the leaves would have risen to the top of the liqiud quicker, because they would not have had to make the totql amount of oxygen.

Human Evolution And The Fossil Record

... between this ratio now and the time is died that allows a date for it
to be established. Potassium-argon dating, another dating method, is possible
due to volcanic ash and rocks found near many fossil sites. Rocks and ash
created in this manner contain potassium-40, but no argon. As time passes, the
potassium-40 decays into argon-40. In the laboratory, the sample is reheated,
and since argon-40 is a gas, it is released. The ratio of argon-40 released to
potassium-40 still present allows for a date to be assigned to objects near the
sample. However, due to potassium's high half-life ...

Predator - Prey Relationships

... to preditation in the sense that the parasite derives
nourishment from the host on which it feeds and the predator derives nourishment
from the prey on which it feeds(Nitecki 1983). Parasitism is different from
most normal predator prey situations because many different parasites can feed
off of just one host but very few predators can feed on the same prey(1973). In
parasite-host relationships most commonly the parasite is smaller than the host.
This would explain why many parasites can feed off of one single host. Another
difference in parasite-host relationships is that normally the parasite o ...

This mic is not good for loud background sound because the mic might not be able to distinguish between the different sounds.

... the sun, moon, and
planets for any given time. Astrologers use this information to draw-up a
horoscope and forecast the "influences" that will affect the soul at that time.
Astrologers usually do not predict actual events in the future. They can only
say what might happen, or could happen, but not what will happen--much like a
weather forecast; although many psychics do make predictions, and astrology is
the tool they use to focus their abilities.
Another common feature of astrology is the comparison of birth charts to
ascertain the compatibility of two people. This is a straightforward method used ...
