QUESTIONS AND VERIFIED ANSWERS
COMPREHENSIVE STUDY GUIDE
●● Indehiscent (dry fruit)
Answer: Do not crack open at maturity.
Seeds are typically dispersed by clinging onto another organism, or wind
●● Sweet flesh fruits
Answer: Contain seeds that can pass through the immune system
without being harmed.
Often dispersed by being eaten and put back into the environment
through waste
●● Aggregate fruits
Answer: develops from a single flower with many separate carpels
Fruit is made up of multiple small fruits that come together
Ex. Raspberry, Strawberry, Blackberry
,●● Simple fruits
Answer: fruits derived from a single carpel or several fused carpels
Ex. Apple, tomato, banana
●● When running t-tests and caption is included: Include->
Answer: Sample size (n=...) or degrees of freedom (n-1)
T value
P value
●● T-test
Answer: a statistical test used to evaluate the size and significance of the
difference between two means
●● The bigger the t-value gets, the _____ the p-value gets
Answer: smaller (inverse)
●● T-test only works when
Answer: the independent value is CATEGORICAL
●● Regression
, Answer: Y=mx+b
●● In regression p-value is supporting:
Answer: the slope
●● Smaller the p-value:
Answer: the stronger support for the slope
●● The tighter the dots on the graph are to the line of best fit:
Answer: the closer the R2 (R squared) value is to 1
●● R2 (R squared) value is always:
Answer: between 0 and 1
●● Life cycles
Answer: Gametic (mainly in animals and some others (protists)) and
Alteration of generations (plants, fungi, and dikaryon)
●● Gametic life cycle
Answer: Starts with single zygote (2n)
Zygote (2n) -> 2 Multicellular diploid (2n) created through mitosis
(division of cells+nuclei, exact copies) -> 4 Gametes (1n) created
