Lab 8: Transformation with Green Fluorescent Protein
Bacteria can be transferred in two different ways either by transformation or by conjugation.
Transformation deals with exogenous DNA from the environment while
Communities and Ecosystems
Energy flow through the ecosystem
Plants are at the bottom of the food chain. They contain the highest amount of energy,
which they obtain from sunlight.
The source of energy for most ecosystems is the Sun.

The Mechanism of Evolution:
Darwin and Wallace suggested a mechanism for evolution: natural selection
It stars with the overproduction of offspring and the presence of natural variation in the
population; then there is a str
The importance of sunlight to ecosystems
The best studied ecosystems are those found on Earths surface, whether they are on
land or in surface water.
Less studied ecosystems, that exist in total darkness, such as those in deep ocea

Darwin and Wallace
o Charles Darwin had the opportunity to travel abroad for a scientific exploration mission
starting in 1831 and lasting for 5 years.
o Darwin discovered that, in 1858, Alfred Russel Wallace had indep
Species and Communities
Limiting factors affect the distribution of species in a community
The distribution of a species depends on the factors, which are both abiotic (non-living)
and biotic (living).
Abiotic factors include:
o Light, for exa
2.9 Outline: Photosynthesis
Photosynthesis converts light energy into chemical energy
o Plants and other photosynthetic organisms produce foods that start food chains.
o We count on the Sun as a constant energy source for both warmth and food production

turnouts. He also claims that young people do not vote because they feel that they are being
ignored by political campaigns and their opinions are different
