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

producers

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?

light energy

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

organ

son, glucose, c6h12o6

photosynthesizer

chemicals (sulfur)

chemosynthesizers

herbivore

1 consumers

omnivores

2 consumers

carnivores

3 consumers

hydrogen and oxygen

carbohydrates have 1:2 ration in what?

no internal membrane, simpler

prokaryotic cell

internal membrane, many different compartments and organelles

eucaryotic cell

the whole living system on the cell

cytoplasm

the oozing stuff in the cell

cytosol

DNA DOGMA

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?

double helix

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

genes

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

3.5 BYO

first life

- 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

Charles Darwin

changes in DNA are passed onto their offspring

darwanism

where people evolved from change over time.

evolution

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?

protists

which Eukarya are considered the most diverse?

to know; a way of knowing

science

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

inductive reasoning

where something new was learned that wasn't previously known

Gallileo Paradigm shift

where things are discovered (expensive tools)

pure science

use things to create new things for our benefit

applied science

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.

deductive reasoning

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

discoveries- scientists
inventions- engineers

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?
