An ecosystem is a natural unit consisting of all plants, animals and micro-organisms (also known
as biotic factors) in an area functioning together with all of the physical (also known as abiotic)
factors of the environment. But what is it that produces a
Background Information: Enzymes are proteins that act as catalysts to speed up chemical
reactions in cells. Enzymes can be affected by changes in temperature. Heat denatures enzymes while
cold temperatures slow rates of reaction. Catalase is a specific ty

Why are Eukaryotes and Prokaryotes in separate
Why did we have to create a whole new taxon level to classify
Prokaryotes and Eukaryotes
The Three Domains
Mostly single celled
1) What is life? Do viruses qualify as being
2) How do viruses cause disease? How
can we use this knowledge to minimize
the effects of viruses on populations?
Viruses lead a kind of borrowed life
Lecture 2 Big Questions
1) How do we organize lifes diversity?
2) Why do we need to?
Taxonomy is the ordered division and
naming of organisms
Linneaus (18th century) published a
system of taxonomy based on

Physiology of Hearing:
1. The auricle directs sound waves into the external
2. When sound waves strike the tympanic membrane, the
alternating waves of high and low pressure in the air
cause the tympanic membrane to vibrate back and
Smoking Effects on a Bleeding Ulcer
This leaves the mucus layer susceptible to erosion and disruption, causing damage of
the gastric mucosa by the acid and formation of gastric or peptic ulcers (Hojgaard et al,
1996) (Cope, 2013 p. 44).
Comparison of the spinach pigments through different methods
Abstract. Photosynthetic pigments in plants have different wavelengths, which are
absorbed and reflected by chlorophylls. When measuring the absorbance of the spinach
extract we ca

To do science is to search for repeated patterns, not simply to accumulate facts.
