Quiz Viruses

Name: 

Viruses

 

 

True/False
Indicate whether the sentence or statement is true or false.
1.
Although viruses do not consist of cells, biologists consider them to be living because they are capable of reproduction.
2.
Wendell Stanley made the important discovery that viruses are not cellular.
3.
Viruses consist of RNA or DNA surrounded by a coat of protein.
4.
Prions are the smallest known particles that are able to replicate.
5.
A virus can only reproduce by controlling a cell.
6.
People can contract the influenza virus more than once because the virus tends to mutate rapidly, avoiding the actions of the immune system.

Photosynthesis

 

 

True/False
Indicate whether the sentence or statement is true or false.
1.
All organisms require energy to carry out life processes.
2.
Animals that live exclusively on a diet of other animals are unable to use carbohydrates to fuel their life processes.
3.
When light hits a plant, all of the wavelengths are absorbed and used to make sugar.
4.
A series of linked chemical reactions in which the product of one chemical reaction serves as the reactant in the next reaction is called a biochemical pathway.
5.
An autotroph is able to make its own organic molecules from inorganic materials and energy.
6.
The major light-absorbing pigment in plants is chlorophyll.
7.
Plant cells use light to make ATP and NADPH.

Evolution

 

 

True/False
Indicate whether the sentence or statement is true or false.

3.
Darwin observed that the plants and animals of the Galapagos Islands were the same as those on islands off the coast of Africa with similar environments.
4.
The book Principles of Geology by Charles Lyell described how changes in land formations can cause species to evolve.
5.
In his “Essay on the Principle of Population,” Malthus said humans were the only population that could continue to grow in size indefinitely.
6.
The two major ideas that Darwin presented in The Origin of Species were that evolution occurred and that natural selection was its mechanism.
7.
The environment dictates only the direction and extent of evolution.
8.
The environment selects which organisms will survive and reproduce by presenting challenges that only individuals with particular traits can meet.
9.
The way an embryo develops is not important in determining the evolutionary history of a species.
