Dd Flashcards
Study of gene structure
Molecular Biology
Made up of all fossils discovered on Earth
Fossil record
Rock forming in water filled
Mineralization
Usually dark or brown
Carbonization
Impression of an organism of rock
Mold
Fossils copy
Cast
Preserved evidence of the activity of organism
Trace Fossil
Change overtime in population
Biological evolution
Study of similarities and differences of different species
Comparative Anatomy
Body part is similar
Homologous structure
The body part has the same function
Analogous structure
Study of gene structure
Molecular Biology
All organism develop
Evolution
There was a special and independent creator of all species
Creationism
Believe in the constancy of all species
Creationist
The father of Evolutionary theory
Charles Darwin
Published zoological philosophy
Jean Baptiste lamarck
It is also known as The theory of transformation
Lamarckism
This theory states that all modern organisms are ascended from a single ancestors.
Theory of common descent
Reduce form of a functional structure
Vestigial structure
comparison of structures that
appear during the development
stages of different organisms.
Comparative Embryology
predicts
that species with common ancestry tend to
show a similarity in the amino acid
sequences.
Comparative Biochemistry
Darwin’s
discovery about the distribution of birds
in mainland
Geographic Distribution
describes the distribution
of organisms
Biogeography
the species that are not closely
related to each other independently develop
similar kinds of traits as they adapt to /
shared similar environment.
Convergent Evolution
process of two or more
related species becoming increasingly dissimilar.
Divergent Evolution
important consequence of divergent evolution
Speciation
individual
evolution of similar traits of two species that
have come from common ancestor.
Parallel Evolution
occurs when
closely interacting species exert selective
pressures on each other so that they evolve
together in a kind of conversation of
adaptations.
Coevolution
The increase of oxygen is one
of the changes that occurred on earth. Before
, O₂ level is relatively few amount but at
present , earth’s atmosphere contains about
21 percent. The increase level of O₂ plays an
important role for living things to survive
and undergo the process of reproduction.
Atmosphere
caused
many species to go extinct. Climate
is one of the abiotic factors that
affect the life of many living
organisms on earth. Species that
cannot adapt to the changing climate
on earth have difficulty finding food
for survival, which cause the species
to die and become extinct.
Temperature
Consists of endocrine glands
Endocrine System
Play a crucial role on maintaining homeostasis
Endocrine glands and hormone
organ whose cells secrete materials
into other regions of the body.
Gland
chemical substances secreted
by endocrine glands directly into the
bloodstream.
Hormone
specific cell a hormone binds to
and acts on (carries a message to).
Target cell
