How does a virus cause disease?
It disrupts homeostasis and equilibrium
It produces toxic substances that harm the body
It rapidly undergoes mitotic cell division that quickly smothers nearby cells
It forms endospores in the body
SARS can be transmitted when an infected person coughs or sneezes. This virus is transmitted in a manner most similar to the transmission of
Smallpox
AIDS
West Nile Virus
Influenza
People infected with (HIV) have an increased risk of dying from secondary infections. Which of these best explains how HIV increases the danger of secondary infection?
HIV produces antigens that damage red blood cells
HIV adds genetic material from harmful microbes
HIV destroys helper T cells
HIV consumes beneficial microbes in the body
The science of classifying living things according to their similarities is called:
Physiology
Zoology
Taxonomy
Taxidermy
What is the importance of a standardized taxonomic system to the scientific community?
To have many different common names for one species
To organize species cells, tissues, organs, and organ systems
To have a universal scientific naming system
To analyze species genetic information
Which of these is demonstrated by the information above?
The need for controlling variables in experiments
The need for classifying and naming organisms scientifically
The importance of predicting trends from scientific data
The importance of questioning experimental evidence
As shown in the cladogram above, what characteristic do ferns, cone-bearing plants, and flowering plants all have in common?
Vascular tissues
Seed production
Flower production
All developed at about the same time
Which organism in the chart above is most distantly related from the other organisms?
Organism A
Organism B

The bullfrog, Rana catesbeiana, is most closely related to the –
Spotted chorus frog, Pseudacris clarki
Asian flying frog, Polypedates leucomystax
Northern leopard frog, Rana pipens
African bullfrog, Pyxicephalus adspersus
The scientific name of a mountain lion is Felis concolor and a house cat is Felis catus. Based on the names, you can determine that these two animals belong to the same:
Species but a different genus
Species but a different family
Family but a different order
Genus but a different species
A dichotomous key is used to –
make cladograms
identify derived characteristics
trace evolutionary development
identify the species of an organism
Correctly identify the kingdom whose members exhibit these traits: most are multicellular, eukaryotic, possess cell walls, do not perform photosynthesis, non mobile representative organisms include mushrooms and mold.
Kingdom Protista
Kingdom Fungi
Kingdom Plantae
Kingdom Eubacteria
To which kingdom do the prokaryotic, single-celled microorganisms that survive the extreme temperatures in geyser, the very cold habitats of the Arctic, or the highly salty habitats of the ocean belong?
Eubacteria
Fungi
Archaebacteria
Protista
“I am a single-celled organism that often lives in the body. Some cause disease, most aid digestion. Sometimes used to process yogurt. In addition, I have a cell wall but I do not have a nucleus.” To which kingdom does this organism belong to?
Eubacteria
Fungi
Plantae
Protista
All plants and fungi are similar in that they both always -
have stems
have a cell wall
grow from soil
perform photosynthesis
Which of the following is an example of how eubacteria and archaebacteria differ in their structure?
Chemical makeup of their cells walls.
Presences of a nucleus in one cell but not other.
Eubacteria are multicellular and archaebacteria are unicellular.
Both live in extreme environments
Multicellular eukaryotes that are usually mobile/obtain food from other organisms probably belong to the–
Kingdom Plantae
Kingdom Fungi
Kingdom Animalia
Kingdom Protista
You are given the above information about cell. What conclusion can be drawn from this information?
it is a single plant cell
it is a Fungal cell
it is a Protista cell
it is an animal cell
Which is a characteristic of members of the plant kingdom that distinguishes them from members of the animal kingdom?
Storage of energy in chemical bonds
Exchange of water with the environment
Use of mRNA during protein synthesis
Use of chlorophyll for solar energy transformation
