-
Specialized, membrane bound structures within cells are known as:
Vacuoles

the “cell highway” that performs transportation duties within a cell
-

The “Endosymbiosis Hypothesis” proposes that:
Mutualistic relationship between different organisms and capable of independent reproduction
-
The overall function of mitochondria is to:
“Cell power plant” Used to generate most of the cells store of ATP -- also Break down fats and sugar to ATP.
-

-
The multicellular kingdoms differ in their:
cells (prokaryotic/eukaryotic) - how they eat - plants: photosynthesis, fungi: absorbtion, animals: ingestion Modes of Nutrition

-
are viruses that attack bacteria.
Bacteriophage
-
HIV infection attacks the:

-
Which of the following is true of viruses outside the host cell?
viruses exist as a protein coat or capsid, sometimes enclosed within a membrane. The capsid encloses either DNA or RNA which codes for the virus elements. While in this form outside the cell, the virus is metabollically inert --- someone double check this!

-
A problem associated with the development of a vaccine against the Bird Flu virus:

50%
-
Which of the following might be effective in preventing the Bird Flu from becoming a pandemic?
Global surveillance, response teams, developing a vaccine.
-
New DNA data will probably be most important in showing evolutionary relationships in kingdom:
???
-
The two kingdoms that are most different are:
Monera vs. Protista
-
Azolla and its associated cyanobacterium are:
Symbiotic and helpful to the growth of other plants
-
An example of why the two kingdom system of classification was not workable is:
Didn’t describe the MANY differences and variations of species efficiently
-
The reason the Kingdom Protista is difficult to characterize is:
Has a very wide and complex variety of species
-
Members of Phylum Sarcomastigophora feed by:
Pseudopods and cilia
-
Characteristics of Phylum Myxomycota include:
Fungus-like i have a feeling this will be one of those “Which of the following is NOT one of …”
-
Diatoms often look like:
light bulbs
-
The evolutionary process of “cephalization” is the development of:
being able to eat and excrete at the same time
-
