Variables/experiment

Biology Unit 1

QuestionAnswer
Describing a concept VS explaining a concept Describe: what happens or what the pattern/data shows EX: listing components, summarizing observations without giving reasons why Explain: stating why or how sm happens EX: link observation to underlying biological principle --> WHY the trend happens
describing a visual representation VS explaining a visual representation Describe: identify physical traits, labels, variables, or basic trends Explain: interpret WHY those patterns occur, predict future outcomes, or connect the model to biological mechanisms.
Quantitative -interval or ratio -characteristics for which measurements or counts can be made -EX: height, weight, number
Discontinuous (discrete) -type of quantitative data -it only includes specific data points with gaps between them
Continuous it includes every point (including fractions) within an interval
if the line on a graph curves, how do you find the rate -draw a tangent line (should only be touching the curve at one point) that touches the given point -pick two points on the tangent and determine the slope/rate
temperature coefficient Q10 equation: rxn rate at (T + 10) divided by rxn rate at T -the increase in reaction rate for every 10 degree C rise in temperature
Qualitative non-numerical and descriptive
ranked Data are ranked in order, although the intervals between the orders may not be equal EX: abundance, frequencies, proportions, birth order in a family, race placement (1st, second, third)
Fair test only one variable is manipulated
augmentation using evidence based reasoning to support a claim
anecdotal evidence -uncontrolled, therefore susceptible to bias -very small sample sizes -only exceptional cases reported -vague outcomes -claim from memory

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.
