Cells are the basic units of life and living organisms are made up of one or more cells
Some prokaryotic cells are "anaerobic" referring to their:
Dont need oxygen to live
Small cells tend to have
Increased membrane surface area
The process of making proteins is:
Transcription & translation --engineer & factory -- copy plans & send them off to be assembled
Specialized, membrane bound structures within the cells are known as
The endoplasmic reticulum is
The "cell highway" that performs transportatiom duties within a cell
Every cell has the following three components
Cell membrane, cytoplasm, genetic material
One of the functions of a vacuole in a plant is to
Store, support, and regulate water
The universal form of energy in all living cells is
Moving hydrogen ions from one side of a membrane to the other
The lifespan of a lipid bilayer in the membranes is generally:
Measured in hours
The "endosymbiosis hypothesis" proposes that
Mutualistic relationship between different organisms and capable of independent reproduction
The overall function of a mitochondria is to

When tectonic plates tipped, they influenced evolution by;
Changing the environment with the movemeny of continents, coastlines varied, sea levels changed
The multicellular kingdoms differ in their
Cells (prokaryotic/eukaryotic) - how theg eat - plants: photosynthesis, fungi: absorbtion, animals-ingestion modes of nutrition
Scientific names are used instead of common name because
Universal and more efficient
Linnaeus names a plant "Siegesbeckia" in order to:
Spite the guy that the plant is named after
In which kingdom do we classify viruses?

capsid, genetic material
_____ are viruses that attack bacteria.
HIV infection attacks the:

Which of the following is true of viruses outside the host cell?
viruses exist as a protein coat or caspid, 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 metabolically inert
