Quiz Bacteria

Name:

Bacteria

True/False Indicate whether the sentence or statement is true or false.
	1.	Gram-negative bacteria have a thick layer of peptidoglycan that stains purple.
	2.	Bacteria lack nuclei and therefore also lack genetic material.
	3.	Bacterial cells have membrane-bound organelles and chromosomes.
	4.	Bacterial cells are usually much larger than eukaryotic cells.
	5.	Bacteria are incapable of movement themselves; they can only get to new locations by growing toward them or by forming endospores and being carried in air or water.
	6.	Some bacteria cannot survive in the presence of oxygen.
	7.	When bacteria undergo nonreproductive genetic recombination, their bacterial chromosome is altered.
	8.	Certain antibiotics have become ineffective against certain strains of bacteria. These bacteria have developed a resistance, which may be passed on from one generation of bacteria to the next.
	9.	The photoautotrophic bacteria are the only bacteria that are indirectly beneficial to humans.
Completion Complete each sentence or statement.
	10.	Spiral bacteria are called ____________________.
	11.	Spherical bacteria are called ____________________.
	12.	Rod-shaped bacteria are called ____________________.
	13.	The procedure used to distinguish between two types of bacterial cell wall structures is called ____________________.
	14.	Protective structures that some bacteria may form under harsh conditions are ____________________.
	15.	The cell walls of Gram-negative eubacteria are composed of a combination of polysaccharide and polypeptide called ____________________.
	16.	Bacteria that obtain their energy by removing electrons from inorganic molecules, rather than obtaining energy from the sun, are called ____________________ bacteria.
	17.	In general, organisms that obtain their energy from sunlight are called ____________________.
	18.	Bacteria that are heterotrophic and feed on dead organic matter are called ____________________.
	19.	A(n) ____________________ is a substance that can be obtained from bacteria or fungi and can be used as a drug to fight pathogenic bacteria.
	20.	Many bacteria are ____________________ and play an important role in recycling carbon, nitrogen, and other elements, while other bacteria are ____________________ and assemble organic compounds from carbon dioxide, nitrogen, and other elements.

Quiz Evolution

Name:

Evolution

True/False Indicate whether the sentence or statement is true or false.
	1.	The theory of evolution states that species change over time.
	2.	The inheritance of acquired characteristics was one mechanism of evolution supported by Darwin.
	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.
	10.	Within populations, divergence leads to new species.
Completion Complete each sentence or statement.
	11.	When an organism becomes ____________________, the tissues are replaced by harder minerals.
	12.	A species that has disappeared permanently is said to be ____________________.
	13.	A change in species over time is called ____________________.
	14.	The process by which organisms with traits well suited to an environment survive and reproduce at a greater rate than organisms less suited for that environment is called ____________________.
