Biology Unit 1 study guide
- What
is the primary characteristic of life that viruses do not meet?
Viruses do not have organization
- Give
an example of an organism responding to the environment as
opposed to an organism being adapted to the environment a dog
going into the shade when it's warm
- if
the eye lens is 10 X magnification and the objective lens is 40
5X what is the total magnification 450
- describe
two important aspects of scientific drawings the scale of the
drawing and labels
- how
was the control group different from the control variable the
control variable you keep the same to everyone in the control
group you don't touch from the very beginning on
- what
is the manipulated variable and the responding variable
represented in the graph below the manipulated variable if the
amount of water and the responding variable in the amount of
height
- what
is a serial dilution
- what
makes duckweed a useful organism for bioassay duckweed grows
very fast making it a useful organism for experiments
- How
do population and community differ the population is a whole and
the community is a part like the population of the world is 20
billion and the community may have 10,000 people
- Given
example of a human tissue organ and organ system human tissue
includes skin cells, organs include liver and kidneys, and organ
system would be the nervous system or the skeletal system.
- organisms
that make their own food are known as
auto trophs
- name
the three domains Archaea,
Bacteria, and Eukarya
- which
taxonomic level is broader order family order is broader than
family
- binomial
nomenclature combines
and species
- what
is a phylogenetic tree is the tree of life
- are
the organisms on the tips of the branches older or younger
species the tips of the trees contain the youngest species and
get older the closer into the truck it gets
- How
is a biological key used is use organizing classify things and
put them into families
- where
the two characteristics used to distinguish sharks from each
other thin and gills
- according
to Darwin white is competition exist constituted exist to get
rid of the weakest species so only the strong survive
- briefly
describe the aspect of Darwin's theory known as gradualism it
means a slow and gradual change in order to survive
- what
does an ecological. Pyramid shows just like the food here made
it shows what other animals live on the bottom of the peer amid
is meditation the next one up will be flies that eat the
vegetation the next peer amid up will be something that eats the
flies and so on until you get the Tigers and big predators
- name
identity depended and density independent limiting factor
- where
are there more producers than consumers and the environment When
the producer is eaten by the consumer, it is an exchange of
energy. Ironically, 90% of the energy that the producer had is
lost, and the consumer only receives 10% of it. Therefore, to
get enough energy to survive, the consumer must eat more
producers, meaning that, to sustain the consumers, there must me
many more producers.
- label
- which
organisms are primarily responsible for nitrogen fixation
bacteria is primarily responsible for nitrogen taxation
- During
photosynthesis plants take up carbon dioxide from the atmosphere
describe two ways a carbon dioxide is released back into the
atmosphere plants use carbon and it makes up organic matter
which is part of all life during photosynthesis plants and other
producers transform carbon dioxide and release `into the
atmosphere as they turned back into organic matter
- Which
biome diverse and why the rain forest is the most diverse
because of all the rain and sun receives with very little human
interaction
- Briefly
describe the the chaparral is a plant that takes up 5% of the
state of California and is very hardy
- how
do mutualism and commensalisms differ mutualism is when two
organisms need each other and commensalisms is when an organism
is not harmed when another one uses it sometimes they don't even
notice
- what
is a niche niche is a term describing the way of life of a
particular species each species is thought to have a separate
unique niche ecologically and a place in the world.
