Flashcards in Chapter 1 Deck (43):
the process of change that has transformed life on earth from its earliest beginnings to the diversity of organisms living today.
decent from common ancestors.
diversity is explained by accumulation of heritable changes
the scientific study of life
novel properties that emerge at each level that are absent from the previous level. small to big
the exploartion of biological systems by analyzing the interactions among its parts
contains membrane encloses organelles, the largest of which is the nucleus. plants, animals, fungi
lacks a nucleus or other membrane enclosed organelles. simpler and smaller. bacteria and archae
the substances of genes. chromosomes contain most of a cells genetic material in the form of DNA.
units of inheritance that transmit info from parent to offspring.
the process by which the info in a gene directs the manufacture of a cellular product
the entire "library" of genetic instructions that an organism inherits is called its genome
studying whole sets of genes (or other DNA) in one or more species
the study of sets of protiens and their properties
the use of computational tools to store, organize, and analyze the huge volume of data that results from high throughput methods
plants and other photosynthetic organisms
animals, feed on producers and other consumers
the output, or product, of a process regulates the very process
DNA is composed of...
nucleotides. A-T, C-G
first arrow transcribed, second arrow translated
what do genes do?
code for protiens. nuclieotides a,t,c,g, code for specific protiens
8 levels of taxonomy
Domain, kingdom, phyllum, class, order, family, genus, species
3 domains of life
bacteria and archea (prokaryote), and eukarya
3 kingdoms of eukarya
protists- eukaryotic but on its own
origin of species
decent with modification, the mechanism is natural selection
individuals that are best suited to their environment are more likely to survive and reproduce. overtime, more individuals in a population will have the advantageous traits. Environment "selects: for those traits.
natural selection does not...
create, but edits heritable variation.
draw a evolutionary tree
explain the mouse experiement p 19-21
white mice and brown mice. controls, why are they neccesary? see sla notes
mechanism of evolution
a loop in which the response reduces the initial stimulus
end product speeds up its own production
way of knowing
search for information that explains phenomena
generalizations from a large number of specific information
a tentative answer to a well framed question
general to specific. "if...then..."
manipulating a factor to see the effect
factors that vary in an experiment
one that is designed to compare an experimental group with a control group
factor manipulated by researchers, mouse color
factor that is measured by the experiment
amount of predation
an explaniation in broader scope than a hypothesis, generates new hypotheses and is supported by a large body of evidence
