What are the three levels of biodiversity - Answer 1) species diversity
2) genetic diversity
3) ecosystem diversity
Genes - Answer Units of inherited information that determine specific characteristics or
functions
Biodiversity - Answer The variety of life in the world
Genetic diversity - Answer The sum of all the different forms of genes present in a particular
species. It also helps the survival of species
Species - Answer A population whose members can breed freely in nature and produce
fertile offspring
Why do farmers grow a single type of corn? - Answer It allows farmers to use the same
equipment, fertilizers and techniques on their land
Monocultures - Answer Genetically uniform farms, that usually have little or no biodiversity
Species diversity - Answer The variety of species and relative abundance of the species in a
given area. This allows ecosystems to survive environmental changes such as droughts, plagues
or disease outbreaks
Ecosystem diversity - Answer The diverse range of habitats, the various organisms that live in
the habitats and the relationships that connect them
What kind of organisms or processes does biodiversity help maintain? - Answer 1) ecosystem
,Keystone species - Answer Species that have a disproportionately large effect on the
ecosystem in which they live, such as a honeybee
What is malaria - Answer A deadly disease that is spread through mosquitoes infecting
people. It is called by a microscopic parasite called plasmodium, that transmits this disease
through it's bite
Why use scientific naming for animals? - Answer To reduce confusion among different
languages around the world, and to have a universal scientific name to each known species
Dichotomous key - Answer A tool used by scientists and non-scientists to identify organisms
with which they are unfamiliar
What does the work "dichotomous" mean in Greek? - Answer "To cut in two"
What does a dichotomous key posses - Answer It possesses a series of questions about an
organism, and each question asks users to choose between two possible characteristics that the
organism may have
Taxonomy - Answer The science of naming, identifying, and classifying species
Binomial nomenclature - Answer A system for naming specific species, which became the
most used classification system in biology, invented in 1750 by the Swedish botanist Carolus
Linnaeus
What are the two main parts of the binomial nomenclature - Answer 1) a two-part Latin
name
2) a hierarchy or ordering of the species into broader and broader groups
Binomial - Answer The two-part Latin name that is part of the binomial nomenclature
Genus - Answer The first part of the specie's name, to which the species belongs
, 5) Order
6) family
7) genus
8) species
Biodiversity - Answer The variety of life in the world or a particular habitat or ecosystem
Ecosystem - Answer a specie's environment
Taxonomy - Answer Science of naming, identifying and classifying species
Protist - Answer Eukaryotic organisms that do not fit into the animal, plant or fungi kingdoms
Cilia - Answer Short, hair-like structures protruding from a cell that move fluid and particles
over the cell's surface; sometimes used for movement and food gathering
Flagella - Answer Long, whip-like structures that some cells use for movement
Pseudopodia - Answer Cellular extensions of streaming cytoplasm that enable a cell to move
in the direction of that extensions
Mycorrhizae - Answer Fungus that forms a mutualistic association with roots of a plant
Phylogenetic tree - Answer A branching diagram that represents the evolutionary
relationships among species or groups
Clade - Answer An evolutionary branch on a phylogentic tree
Phylogeny - Answer The evolutionary development and history of a species or group of
organisms
Morphology - Answer Study of form and structure of organisms
