What is binomial nomenclature?
A scientific name of an organism using its genus and species name
This term describe non-living things
abiotic
Which symbiotic relationship is described by both organisms benefiting from each other? Provide an example.
mutualism (ex. insect & flower)
When viewing a graph, what is a key indicator that it is displaying variation?
The graph for variation is always bell-shaped
Who is responsible for developing the classification organisms based on similar characteristics?
Carlos Linneas
Which kingdom is divided into categories called Phyla or a Phylum?
Animalia (invertebrates & vertebrates)
What type of organisms are found at the base of any trophic level?
Producers (autotrophs)
Which symbiotic relationship describes a tapeworm in an organism?
parasitism
Name the 4 evidences of evolution
Fossil records
Comparative Anatomy (Homologous structures, Analogous structures, Vestigial Structures)
Comparative Biochemistry (DNA comparisons) Comparative Embryology
The "Class" taxa is defined by which charactisitic?
Mammalia: Vertebrates with mammary glands
Which part of the plant allows for gas exchange through transpiration?
stomata
This term describes the removal of trees on a large scale which results in the increase of CO2 and the decrease of O2?
Deforestation
Which consumer type describes organisms such as fungi, bacteria, and vultures?
Detritivore
The creation of new species (speciation) can occur in 2 ways. Which one involves the presence of physical barriers?
Geographic Isolation
lakes, rivers, dams, oceans, islands
Name the 5 kingdom system
Monera → bacteria
Fungi → mushrooms and yeast
Protista → protozoans
Plantae → plants
Animalia → animals
Name the 3 kinds of symmetry and provide an example of each one.
Radial - starfish
Bilateral - human
Asymmetrical - coral or tree
When viewing a graph, which is a key indicator that it is displaying exponential growth?
J-curve
This is the result when 2 species share the same niche
competition
Which type of natural selection results in the formation of 2 new species?
Disruptive Selection
[The average trait is selected against and you get
both extreme traits]
Which kingdom system has adaptive structures to help them survive in their environments? Name 2 of them.
Protista
1. Contractile vacuole-removes water
2. Eyespot-detects light (photosynthesis)
3. Pseudopodia-movement & feeding
4. Cilia-movement
5. Flagella-movement
Mosses
(no roots & no vascular system; most primitive)
How much energy is used by organisms at each trophic level?
90% of the available energy is used by the
organism at each level, only 10% is available to
the next level
Give the example of commensalism that was provided in the PowerPoint.
Moss growing on a tree
