What is science
science is a body of knowledge and a process for gaining knowledge about our world as a result of info which is learned using carefully planned study methods
WHat is biology
biology is the study of living things, the process of living things, interaction between living thing and living thing, and non living things
What is the sicentific method
the technique used to solve problems and gain info though logical thinking, the squence is critical
steps of the scientific method
Define the problem, Gather relevant research, make hypothesis, test it, record observations, and draw a conclusion
DIfference between an independent variable and a dependent variable
AN independent variable is the factor tht manipulates your set-up in ourder to test the hypothesis and the dependent variable changes as result to the independent variable
second set-up with no variable involved for comparison reasons
Conclusion are based on what
the outcome not the hypothesis-if the experiment supports the hypothesis it has been verified
if hypothesis is varified ....
retest results and record and share them
what is the metric system
most commonly used system based on units of ten aNd is more accurate and easier to use
What are the prefixes
kilo, hecto, deka, base unti, deci, centi, milli, micro
how are liquids measured
they are measured in a graduated cylinder liquid is poure d onto the mwniscus and read from the bottom of it
What is the freexing point, and boiling point of water, and what is the normal body temp
0 degrees celcius, 100 degrees celcius, and 37 degrees celcius
can u add or subtact unlike units units
no u can unlike add or subtract like untis
WHat is a data table used for
to record numerical data
what do bar grpahs show
the only show comparisons
what do line graphs show
they show relationships between 2 variables
where is the independent and dependent variable on a line graph
the independent is on the x and dependent on the y
what does every grpah need
units, title, key/legend
Taxonomy is ...
the sicence of classification
hwy do we classify
common language, structural similarities, and ancestrial similarites
List the the levels of classification in order from general to most specific
kingdom, phylum, class, order, family, genus, species
Speicies is ....
a group of organism that are similar in structue, can mate under natural conditions to produce feritle offspring
What is the linnean classification system
uses homologies to group species into larger or more general catigories and is the foundation for more modern classification
What is binomial Nomenclature
the two name namming system-> first name is genus and is capitalized or underlined/italicized second name is epithet name-> DONT CAPITALIZE and underline/italicize
what is the 5 kingdom classification system
if it is prokaryotic or eukaryotic, mutlicellular or unicellular, sexual or asexual, autotrophic or hetertrophic, aerobic or anaerobic, homologous, analogous, or vestigal structures
What is the diff between prokaryotic and eukaryotic
eukaryotic is complex and prokaytoic is simple
What is the diff bewtween autotrophic and heterotrophic
Autotrophic sythesizes own food heterotrophic feeds off other organisms
what is an homologous structre
are similar anatomically but different in purpose
what is an analogous structure
similar functions but are different anatomically
Vestigal structures
serve no purpose but have been passed own through generations
WWhat are the 5 kingdoms
monera, plants, protista, animal, fungi
3 characterisitcs of monera are..
prokauyotic, small circular DNA w/e protiens, reproduce thorugh fision or budding,lack membrane-bound organelles
What is the diff between archaea and eubacteria
Archaea has distinct ribosomal RNA and represnts first organisms Eubacteria is autotrophic or heterotrophic or aerobic or anaerobic
3 characteristics of protista are...
eukaryotic microorganisms, typically aquatic, and is the left over kingdom ie:amoebas and algae
3 characteristics of fungi are ...
eukaryotic, multicellular w/ cell walls, heterotrophic decomposers, and non-mobile ie: molds and mushrooms
3 characteristics of plants ...
eukaryotic, multicellualr w/ cellulose cell wall, photoautotrophiv ie trees mosses ferns
3 characteristics of Animalia
eukaryotic, motile, multicellular, &heterotrophiv
what is the human phylogeny
Kingdom= animalia -> Phylum=chordata -> class= mammalia -> order=primates -> family=hominidae -> Genus= HOMO -> species -> homo sapiens
primates can ...
see in 3-D, have complex brains and athumbs and flexible shoulders
humans are primates b/c ..
we have thumbs, brains, & 3-D eyes nucleotide sequences in DNA,humans probaly evolved form african apes
what is life
