Introduction to Biology | Questions & Answers | Grade A|
100% Correct (Verified Solutions)
Coevolution Event - answer-:The process by which two or more species evolve in tandem by
exerting selection pressures on each other
Karyotype Disorder - Down Syndrome - answer-:
DNA vs RNA Purpose - answer-:DNA - carries genetic information
RNA - transports genetic information
Population - answer-:group of organisms of one species that interbreed and live in the same
place at the same time (e.g. deer population) *one species
Community - answer-:an interacting group of various species in a common location. For
example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil
containing bacteria and fungi, constitutes a biological community.
Ecosystem - answer-:A system that includes all living organisms (biotic factors) in an area as well
as its physical environment (abiotic factors) functioning together as a unit. Supplement. An
ecosystem is made up of plants, animals, microorganisms, soil, rocks, minerals, water sources
and the local atmosphere interacting with one another
, Biosphere - answer-:The biosphere is the zone of air, land and water where organisms exist. It is
commonly known as the global sum of all ecosystems
Commensalism - answer-:a relationship between individuals of two species in which one
species obtains food or other benefits from the other without either harming or benefiting the
latter.
Predation - answer-:A of symbiotic relationship between two organisms of unlike species in
which one of them acts as predator that captures and feeds on the other organism that serves
as the prey.
Symbiosis - answer-:Sometimes beneficial, sometimes harmful, these relationships are essential
to many organisms and ecosystems, and they provide a balance that can only be achieved by
working together.
Competition - answer-:An interaction between organisms or species in which both the
organisms or species are harmed
Parasitism - answer-:A non-mutual relationship between species, where one species, the
parasite, benefits at the expense of the other, the host
Herbivory - answer-:When animals eat plants or plant-like organisms, and a herbivore is a type
of animal that eats plants or plant-like organisms
Food Web - answer-:
Nitrogen Cycle - answer-:continuous series of natural processes by which nitrogen passes
successively from air to soil to organisms and back to air or soil involving principally nitrogen
fixation, nitrification, decay, and denitrification.
