biosphere, ecosystem, community, population, organism, organ system, organ, tissue, cell, organelle, mollecule
levels of organization
ecosystem is the area with all the organisms, community is the organism in the area, and the population is all of the species of one type of organism
difference between ecosystem, community, and population
plants that provide food for a certain eco-system
we could be is other organisms ate our wastes, or us alone, though we are more in the consumer category
Are we producers? explain.
consumers, tak- in, use, or eat producers
relationship producers and consumers
they decompose wastes, remains of dead. Or they change complex matter into nutrients for plants
what is the function of decomposers?
fungi and bacteria
examples of decomposers
more animals and wastes around. Also plants would die due to lack of nutrients
What would happen if decomposers didn't exist
producing and consuming
Two major processes that make up the dynamics of an ecosystem?
what does the sun provide?
they use photosynthesis
What do plants use from the atmosphere to make chemical energy?
take in nutrients and release CO2
what do consumers take in and release
a bunch of tissues working together
son, glucose, c6h12o6
hydrogen and oxygen
carbohydrates have 1:2 ration in what?
no internal membrane, simpler
internal membrane, many different compartments and organelles
the whole living system on the cell
the oozing stuff in the cell
DNA- RNA- PROTIENS
regulate its internal environment, take in and use energy, develop and maintain its complex organization, create new cells, and grow and repair themselves, photosythesis
5 things a cell can do
it means that a cell is shaped and designed to do the work that it does
what does it mean to say a cell illustrates "emergent properties"?
it is a complex organization that is a combination of composers.
what is a system?
prokaryotic and eukaryotic
what two types of cells that we find on this planet that represent what we know as life?
what is the structure of DNA
one side of DNA that contains parts of the 4 building blocks that make up DNA
what is a helix
information that comes from the parents to their offspring
yes, though no one has the same DNA other than identical twins
is bacteria DNA made from the same building blocks as our DNA
order, regulation, growth and development, energy processing, response to the environment, reproduction ,evolutionary adaption
7 things all organisms have in common with each other
- wrote the origin of the Species
- sailed to the galapagos Islands and studied all the different animals
- studies finches and saw that they adapted to the area that they were in to help them survive
changes in DNA are passed onto their offspring
where people evolved from change over time.
a particular kind of organism
what is a species?
a branch of biology that names and classifies species
what is taxonomy?
they are groups that each organism fits into. We have dozens of kingdoms
what are kingdoms? and how many are there in our society today?
Bacteria, Archaea, Eukarya
what are the 3 domains
bacteria and archaea
What domains are made up of prokaryotes?
single cell organisms (very small)
so what are the the organisms in prokaryotes like?
which Eukarya are considered the most diverse?
to know; a way of knowing
god, or supernatural power
what things are outside of science to explain?
discovery- something that i found or studied and found
HB- is with trial and error
what is the difference between "discovery science" and "hypothesis- based science"?
conclusions based on a type of knowledge
where something new was learned that wasn't previously known
Gallileo Paradigm shift
where things are discovered (expensive tools)
use things to create new things for our benefit
a proposed explanation for a set of observations
what is a hypothesis
the logic used in HB science to come up with ways to test hypotheses.
testable and falseable
two important properties of scientific hypothesis
where there will be one snake that is poisonous and another with the same colors that is not poisonous. so that neither of them will be prey.
mimicry in snakes
with out a control group we wouldn't know the different in the different ways that the normal one
controlled experiments important?
technology uses science knowledge for a certain purpose
difference between science and technology
speaks or discoveries vs. inventions
in religions with evolution
with economy- because of new discoveries in how people work
polotics- make the president make new decisions based on discoveries
science play a role in polotics, economic values, and cultural events?
