BIO 1

QuestionAnswer
observations made to gain knowledge about a subject .
inferences explanations or interpretations of the observations.
models representation of a system or phenomenon that can be used to test hypothesis and make predictions.
hypotheses educated guesses based on OBSERVATIONS, INFERENCES AND MODELS... tested through experiments.
scientific theories explanations of patterns observed in nature that are supported by large bodies of evidence.
theories NOT THE SAME AS LAWS but they do describe repeatable patterns in nature.
alleles different forms of a gene .
genes unit of heredity that code for specific traits.
diploid organisms two sets of chromosomes, each containing one gene for each allele.
sister chromatids copies of a chromosome produced during cell division.
gene expression the process of making proteins from the information encoded in DNA .
single base pair mutation (in a protein coding gene) can change the amino acid sequence of the encoded protein.
functional approach seeks to understand a phenomenon by identifying the different parts/components of the system being studied + how they work together to produce the observed behavior or outcome.
how to apply a functional approach investigate the structure and chemistry of a geckos toes to see how they stick to surfaces- this is functional because you're investigating the structure and chemistry of the geckos toes to see HOW they stick to surfaces.
comparison study goal is to identify significant differences/similarities and explore the factors that contribute to them.
causation study a type of research study that seeks to establish a cause and effect relationship b/t two variables.... goal is to see whether a change in one variable causes a change in another variable.
association study study that looks for a statistical relationship between two variables to see if they're related.
mathematical model representation of a system using mathematical concepts and languages. used to describe, analyze and predict the behavior of a system being studied. EQUATIONS.
The correct order of the scientific model is make observations, make inferences, build model, form hypothesis, test hypothesis. (O.I.M.H.H) OBVIOUSLY. IM. MORE.HOT.HATER.
scientific theory is most closely related to which of the following explanation.
which of the following statements about scientific theories is correct theories are explanations of observable patterns.
which of the following is TRUE of most processes in biology they are unobservable.
pattern a graph of CO2 concentrations over time is best described as a pattern; shows the changing levels of CO2 in the atmosphere which is a pattern that can be observed and analyzed.
scientific law statement that describes a natural phenomenon or relationship b/t variables, expressed in mathematical terms and backed by empirical evidence.
strong biological explanations explanations that include multiple causes, in order to explain complex living systems.
historical or backward looking approach seeks to explain a phenomenon by looking at its origins or historical development.
contextual or upward-looking approach seeks to explain a phenomenon by considering its relationships to larger systems or contexts.
functional or downward looking approach explains a phenomenon by examining its purpose or function.
conflationary or upward looking approach an approach that combines elements of the contextual and functional approaches.
disease genes genes that are associated with an increased risk or developing a particular disease.
SCIENTIFIC LAW DESCRIPTION OF A NATURAL PHENOMENON.
SCIENTIFIC THEORY EXPLANATION OF WHY THE PHENOMENON OCCURS.
natural experiment A natural experiment is a type of study in which the exposure to a treatment or intervention is determined by nature or other factors outside the control of the investigator.
protein coding sequences are easier to find then transcriptional regulatory sequences bc they can be found using the genetic code.
A protein is found in lung cells of an animal but not in brain cells of the same animal. What process most likely accounts for this? the gene encoding the protein is transcribed in lung cells but is not transcribed in brain cells.
Which of the following is TRUE about the huntingtin gene? Some variants of the huntingtin gene are associated with Huntington's disease and some are not.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
