Rate Of Reaction Bunsen Burner
1,230 words
Investigate A Factor Which Affects the Rate Of
Fermentation Of Yeast This experiment is
investigating one of the factors which affects the
rate of fermentation of yeast. Several factors
affect the rate of reaction: 61656; Increasing
the concentration. (See the lock and key theory. )
If the substrate (glucose) is increased, then
there would be more keys for the locks, therefore
an increase in reactant concentration leads to an
increase in reaction rate. 61656; The surface
area, the bigger t...

... onward sources, from a textbook, encyclopedia,
and preliminary work that I have done in class. I
have shown my results on a bar chart and a line
graph. On the line graph, I have drawn a curve of
best-fit. There were no anomalous results. From my
results, and my graph, I have found out that as
the temperature of the enzymes (yeast in this
case) is increased, the rate of reaction speeds
up. However, when the temperature reached a
certain point, (about 40 degrees Celsius), the
enzymes became de...

Favorable Trait Natural Selection Species
332 words
Creationism is the belief that the origin of the
universe, of life, and of the different kinds of
plants and animals on earth are due to the
intervention of God. The other belief is the
belief of evolution developed by Charles Darwin
that contradicts creationism. Evolution states
that all species including humans descended from
other species. It also states that each species
derived from an earlier less complex one.
Evolution is determined by natural selection,
which means that an organism with ...

Scientific Method Three Parts

Aristotle, Galileo, and Pasteur can be said to
have contributed significantly, each in his own
way, to the development of "The Scientific Method.
" Discuss. What is the scientific method? In
general, this method has three parts, which we
might call (1) gathering evidence, (2) making a
hypothesis, and (3) testing the hypothesis. As
scientific methodology is practiced, all three
parts are used together at all stages, and
therefore no theory, however rigorously tested, is
ever final, but remains at...

Dawkins Uses The Example Dawkins Explains Genes
1,178 words
In the popular science book, The Selfish Gene,
Richard Dawkins explains his theory of evolution,
and its occurrence for the good of the gene rather
than the good of the species or individual.
Dawkins believes the gene to be practically
immortal, carrying on generation upon generation.
By calling them selfish Dawkins describes a genes
strategy of competition for survival, its tendency
to behave in a manor suited to ensure its
propagation. Genes are competing directly with
their alleles for surviv...

Spindle Fibers Asexual Reproduction
512 words
Cellular Reproduction is the process by which all
living things produce new organisms similar or
identical to themselves. This has to happen
because if a species were not able to reproduce,
that species would quickly become extinct.
Reproduction consists of a basic pattern: the
conversion by a parent organism of raw materials
into offspring or cells that will later develop
into offspring. The reproductive process, whether
asexual or sexual always involves an exchange in
hereditary material from ...

animals for the benefit of medical and scientific
research is ethical. Whether it is or isn't, most
people believe that some form of cost-benefit test

where our consciousness comes from. Can this

born free of the gene that allows sickle-cell
anemia, despite both her parents being carriers.
How was this possible? In the embryonic cell from

the flawed gene. Could a genius clone Hitler?

Human Insulin Biotechnology One

Biotechnology as defined by the Merriam-Webster
dictionary is the manipulation of biological
organisms to make products that benefit human
beings. This in essence is biotechnology but one
might still be confused by this topic. It is often
thought that biotechnology is about crazy
scientists who are making new types of animals
with two heads, six legs, and many more
monstrosities. This information is far from the
truth. Biotechnologists do make new creatures but
